Research Projects

d-LIVER

Description: Within the EU project ‘d-LIVER’ the Fraunhofer Institute for Biomedical Engineering together with 13 European partners develops an IT-based liver support system which permits medical observation of patients with chronic liver disease. The system can be used inside a hospital as well as in a home environment. For the reliable application of the system in the ambulant area and in particular in a home environment it is essential to monitor the system and the patient during liver dialysis. To this end new sensors and information and communication technologies will be developed. Within ‘d-LIVER’ we will use bioreactors with living liver cells which can perform the detoxification and synthesis functions of the liver as opposed to adsorption or filtration techniques which have no metabolic capability. Furthermore, innovative technologies and sensors will be developed to facilitate large-scale cultivation of fully functional liver cells under controlled conditions.
Contribution of IBMT: The working group Microsensors & Microfluidics of the Fraunhofer IBMT develops new sensors to allow the quality and efficacy of the cells within the bio-artificial device to be continuously self-monitored. Impedance spectroscopy is used as the main measurement principle. The sensors will be integrated into the bioreactor in cooperation with other partners. At Fraunhofer IBMT, the tasks are carried out in cooperation with the working group In-vitro Culture Technologies. Furthermore the working group Home Care & Telemedicine deals with all IT aspects of the liver support system.

BIO-REEL

Description: The interdisciplinary research project BIO-REEL combines the fields of biotechnology and cell biology as well as production techniques and micro techniques. The advantages of soft lithography (high lateral resolution) will be brought together with those of industrial printing processes to allow imprinting of large-scale substrates with high throughput speed. The project aims at designing highly efficient production equipment for the on-site immobilisation of proteins on polymer foils in a rotative process. Targeted applications are drug development, tissue engineering, and stem cell research.
Contribution of IBMT: Fraunhofer IBMT is responsible for the selection of the polymer foils, the design of microstructured printmasters, and the analysis of the immobilised protein layers.

REMOTE

Description: The objective of REMOTE is to assist elderly people with health impairment in everyday life, so that they are able to live their life self-determined as far as possible. By means of information- and communication technology we will create a network comprising both social contacts and tele-health-services. Among a multiplicity of commercial sensors, two newly developed sensors by IBMT will be used. The new sensors detect the wetness of the oral cavity and the maxillary movements to infer eating and drinking habits. The complete network will be tested in selected locations in different places all over Europe.
Contribution of IBMT: Fraunhofer IBMT is responsible for the development of miniaturised mouth-worn sensors for measuring the wetness of the oral cavity and the maxillary movements.

UlcusPrevent

Description: For the treatment of diabetes and decubitus patients, the control of pressure load and pressure distribution of the affected body regions plays an important role. By employing innovative microsensors which will be implemented flexibly in different textiles, ulceration shall be effectively reduced, well directed and continuously. This textile based system will record and analyse pressure conditions of endangerd body regions, indicating overload conditions to the patient, who will then be able to relieve the corresponding body part, e. g. toe, heel or pelvis.
Contribution of IBMT: Fraunhofer IBMT is responsible for the wireless data link between the textile measuring unit (e. g. decubitus sock) and a processing and alarm unit placed at the upper part of the body. In addition, IBMT develops the electronics and the required firmware.

Rapid SPR for Parallel Detection of Pathogens in Blood (RaSP)

Description: RaSP intends to develop a very fast, cheap and at the same time very sensitive method which has the potential to detect more than 100 blood pathogens simultaneously. RaSP aims at simultaneously detecting the pathogens HIV, hepatitis C, hepatitis B and syphilis to demonstrate the capabilities of the system. A simple and small desktop system which is easy to use and which leads to accurate results will be set up allowing to detect the presence of any of the mentioned blood pathogens within 10-20 minutes. Thus, infected blood could be excluded at an early stage from the blood banking procedure. RaSP exploits a new type of surface plasmon resonance (SPR) transducing principle, that allows very fast and sensitive testing. The immunosensing diagnostic assay is based on the very specific immune reaction between antigens and antibodies.
Contribution of IBMT: Fraunhofer IBMT coordinates the project and is furthermore responsible for the development of all micro-fluidic components.

Brain Shunt

Description: Within the MOTIV-project „Brain Shunt“ the worldwide one and only active implant for the treatment of hydrocephalus diseases has been developed. It works as a binary switch actuating the liquor drainage by means of a hard-coded opening frequency dependent on the time of day. By means of a special programmer the hard-coded opening frequency can be changed non-invasively over an inductive interface. Thus, the therapy can be adapted individually to the patient’s requirement.
Contribution of IBMT: Fraunhofer IBMT is responsible for the micro valve, the wireless powering, the wireless communication as well as for the entire electronic system and software.
