Description: The aim of the project is to reduce the number of animal experiments by developing an analysis platform consisting of a combination of a fluidic organ culture system (in vitro) and in silico analysis of disease mechanisms. VISION develops and validates an in vitro / in silico analysis platform for inhalation toxicology studies, which will largely reduce and replace animal experiments in regulatory, application-oriented and basic research. At the same time, the microfluidic system opens up new possibilities for modelling disease processes in vitro and in silico. A disease model of COPD (chronic obstructive pulmonary disease) will be developed in close cooperation between biomedical technology, biological medical science and application-oriented SMEs, which combines different cell and tissue types in a physiologically relevant manner and permits detailed biological, pharmacological and toxicological analysis.
Contribution of IBMT: Within the project, the Fraunhofer IBMT has the following tasks: a) Implementation of an in vitro lung/liver model system to simulate the lung barrier and the metabolism process in the liver, b) investigation of human toxicological effects of pulmonary uptake of pollutants, c) analysis of transport and accumulation of pollutants using in vitro studies.

Description: The overall project goal is a novel electrostimulation system consisting of electronics worn externally on the body and a purely passive, highly miniaturized implant in the form of a biocompatible encapsulated magnetic body. The electronics worn on the body emit time-varying magnetic fields in the direction of the implant. They are concentrated by the implant and directed to the stimulation site. According to the Maxwell equations, the time-varying magnetic field results in a time-varying electric field, which, if all parameters are selected appropriately, is generated in the tissue to be stimulated and triggers an action potential there. The stimulation should be as effective and spatially resolved as is the case today with very complex implants.
Contribution of IBMT: The work of Fraunhofer IBMT focuses on the simulation of the overall system, the development of the implant bodies and the testing of the assembled systems.

Description: In the FlexiRet project we are developing a holistic concept for prosthetic vision up to a functional demonstrator. The concept is based on a minimally invasive approach, which allows the use also in patients with only partial loss of vision as well as the individual adaptation to the limitation of the individual patient. The implant consists of a mosaic-like array of thin silicon-based photodiodes with integrated thin-film stimulation electrodes combined with a foil substrate. The implant is surrounded by special thin implant encapsulation layers to protect the implant electronics from the humid environment in the eye.
Contribution of IBMT: The Fraunhofer IBMT designs the electrodes on the basis of computer simulations and develops the processes for combining the thinned photodiode array with a foil substrate.

Description: The project I-Call aims at the technical development and realization of a safe and secure signal transmission between implants based on ultrasound. So-called cMUTs (capacitive micromachined ultrasonic transducers), already known from ultrasound-based imaging, are used as ultrasonic transducers. In addition to tailor-made cMUTs for wireless communication, special ASICs for controlling the cMUTs and for processing the ultrasound signals, we develop communication protocols for communication via ultrasound. Although cMUTs made of silicon are biocompatible per se in contrast to established ultrasonic transducers and thus suitable for implantation, we aim at using them primarily in a hermetic metal housing (e.g. titanium). Project tasks also comprise the development of suitable housings and methods for sound coupling.
Contribution of IBMT: a) Simulation and realization of cMUTs in bulk micromachining and their characterization, b) development of implant electronics and firmware for controlling implant communication.

Description: This project deals with the investigation of approaches for the automation of handling processes in the cryopreservation and storage of biological samples. The general advantages of process automation compared to the purely manual process are on one hand the exclusion of health hazards for the personnel by sample contact or cold burning, on the other hand an accidental swapping of the samples or their damage by temperature fluctuations is prevented. It is also expected that the efficiency, speed and reproducibility of the handling processes will be increased. A promising approach is to use a manipulator based on a parallel kinematic structure. Such structures allow the decoupling of the drives from the low temperature range (-130 °C to -196 °C) by transmitting the drive motion via passive joints to the end effector.
Contribution of IBMT: Within the framework of the project, the Fraunhofer IBMT has the following tasks: a) Investigation of approaches for wireless energy transmission into the cryogenic working environment for the power supply of a gripper system and (if required) a joint heating system, b) Investigation of potential actuators as well as development and evaluation of a compact and energy-efficient gripper system.

Description: With a prevalence of 3-5%, amblyopia is one of the most common causes of visual impairment during the first years of life. The aim of the InsisT project is to develop interactive and context-sensitive shutter glasses with sensory feedback for the individualized therapy of amblyopia in children. Using an interactive, user-friendly app for smartphone and tablet, it also involves the family of the child's patient as well as the treating medical staff in the follow-up and therapy optimization. The spectacles provide the patient with immediate, child-friendly feedback in case that the spectacles are removed or worn incorrectly and also generate motivating feedback on a daily basis. The context-sensitive occlusion mechanism recognizes when the occlusion of the healthy eye must be interrupted in order not to disproportionately impede the child or even expose it to a safety risk.
Contribution of IBMT: a) Sensors that detect if the glasses are removed or worn incorrectly. b) Sensors and machine learning algorithms to determine the patient's physical activity (sitting, running, etc.). c) Intuitive software for smartphone and tablet to transmit feedback on the therapy adherence of the child patient to its family. d) Secure, data protection-compliant and user-friendly web application for medical personnel to provide and process the data generated during the therapy period.

Description: The fear of spiders (arachnophobia) is the most widespread specific phobia. The proven treatment for arachnophobia is exposure therapy. This means that the patient is confronted with the fear-inducing stimulus, i.e. a spider, in reality. Although arachnophobia is well treatable with exposure therapy, studies show that between 60 and 80 percent of patients do not seek therapeutic help, although this phobia causes suffering and significantly restricts the quality of life of those affected. In the BMBF project DigiPhobie, a digital therapy system is being developed that will allow arachnophobic patients to receive exposure therapy at home in the future. This innovative system consists of a digital therapy environment, wearable data glasses (virtual or augmented reality) and wearable sensors that measure vital parameters during a therapy session (biofeedback).
Contribution of IBMT: Within the scope of the project, the Fraunhofer IBMT has the following tasks: a) Software development and system implementation for biofeedback control, including wearable sensors for recording heart rate variability, skin conductance and respiratory rate, b) Machine learning algorithms for classifying anxiety levels from the measured vital parameters, c) Software development of the web-based database for therapy management.

Description: In cooperation with ten other partners, the Fraunhofer IBMT develops a multimodular screening platform that combines several microfluidic modules. Each module represents a tissue of the organism (e.g. intestine, liver, kidney) and consists of a miniaturized system for cell cultivation. A flexible fluidic concept enables the interconnection of the modules. The characterization of the cells is carried out with optical and electrical systems integrated into the platform. The platform simulates the pathway of toxic substances (e.g. nanomaterials) through the human body and can be used for risk assessment of toxic substances e.g. within the framework of REACH. The effects triggered by nanomaterials are investigated at the molecular, cellular and organ level. The data obtained by means of the screening platform can be used for pharmacokinetic modelling and serve to reduce and avoid animal experiments within the framework of 3Rs. Possible applications for the multimodular screening platform include pharmaceutical research and environmental analysis.
Contribution of IBMT: Within the framework of the project, the Fraunhofer IBMT works on the following tasks: a) development and fabrication of the multi-organ platform with integrated miniaturized systems for cell cultivation, b) integration of optical and electrical systems for cell characterization, c) development of new in vitro models for the investigation of toxicological effects of nanomaterials.

Description: The interdisciplinary research project BIOGRAPHY combines the technical disciplines of micro laser ablation, roll-to-roll equipment and printing of micropatterns with the biological application fields of cell biology, virology and biosensors. A key aspect is the development and use of a new graphene-based ink which is electrically conductive, optically transparent and, at the same time, biocompatible. All these features can be achieved when graphene is used as the main component of the ink. The new inks and print processes are to be used for the development of low-cost disposable sensors for direct virus detection by online monitoring of the virus-induced cytopathic effect (CPE) by impedance spectroscopy. Furthermore, we will monitor the inhibition of the CPE in the presence of neutralizing antibodies. A possible application field is the automated validation of vaccines.
Contribution of IBMT:
Within the project, the IBMT will a) develop processes for roll-to-roll printing of electrically conductive graphene structures and protein patterns, b) fabricate roll-to-roll printed sensors comprising graphene/protein multilayers, c) validate the biocompatibility of graphene ink and the suitability of printed graphene/protein multilayers concerning the envisaged biosensor applications.

Description: Alongside diseases of the cardiovascular system, tumours are among the leading causes of death in Germany. The presence of tumour cells in peripheral blood and their quantitative changes over time are important indicators diagnosing a tumour, evaluating the success of tumour therapy and making a prognosis for the patient. The latest high-throughput methods of molecular biology, microscopy and molecular imaging allow anunprecedented breadth of analysis on a single-cell basis. However, these cells have to be isolated before further cell investigation is possible. The standard methods for qualitative and quantitative cell characterization include cell sorters with and without fluorescence activation. These methods do not provide satisfactory results for circulating tumour cells in blood. The overall objective of RamanCTC is to significantly improve identification and characterization of tumour cells circulating in the blood of cancer patients.
Contribution of IBMT: The Fraunhofer IBMT is exploring new microchips that allow high-throughput cell characterization. This is possible due to the precise and defined positioning of a very large number of cells, and thus their quasi-parallel investigation.

Description: The main objective of the NANODETECTOR project is the development and validation of technologies for the detection and analysis of single nanoparticles in complex environments. The project is based on a new experimental phenomenon: single sub-wavelength objects give rise to optical signals in surface plasmon resonance microscopy. This provides a unique possibility forthe  ultrasensitive on-line detection of nanoparticles. The technology will be implemented in a compact device, tested in different liquid and gas phases and applied for various practically relevant analytical tasks. The system can be used to monitor the safety of the environment during production and exploitation of nanoparticles and nanomaterials. Within the NANODETECTOR project, the new diagnosis method will be applied by producers of nanoparticles and nanoparticle-based materials. It will be used to monitor workplaces and waste material for exposure to nanoparticles. It will also be examined whether nanoparticle-based materials release nanoparticles over time. Another application scenario is the investigation of water and other transparent non-colloidal drinks (juices, white wine, etc.). More complex media will also be tested.
