A platform of an electronic capsule is being developed for multi-task medical assistant application. It includes a near field telemetry unit for bidirectional communication system of 115 KHz low carrier frequency for inductive data transmission suited for human body energy transfer. The system triggers an actuator for drug delivery in various time and release forms via wireless external control, it has the ability to record temperature, measure pH of the body (additional sensors), and retrieve data to the outside. It consists of a 32bit processor, memory, external peripheries, and detection facility. The complete system is designed to fit small-size mass medical application with low power consumption, size of 7x25mm. The system is designed, simulated and emulated on FPGA. A final layout of the complete chip design is still under progress.
A new electronic capsule with bidirectional communication system is being developed for multi-task application. The capsule is designed to be a platform for medical assistant application inside the body. The designed telemetry unit is a synchronous bidirectional communication block using continuous phase DQPSK of 115 kHz low carrier frequency for inductive data transmission suited for human body energy transfer. The communication system can assist the electronic pill to trigger an actuator for drug delivery, to record temperature, or to measure pH of the body. It consists additionally to a 32bit processor, memory, external peripheries, and detection facility. The complete system is designed to fit small-size mass medical application with low power consumption, size of 7x25mm. The system is designed, simulated and emulated on FPGA. A final layout of the complete chip design is still under progress.
In this paper, a complete passive transponder device has been discussed which is meant to monitor leakage in silicone breast implants. The passive tag operates in the HF frequency range of 13.56MHz using RFID ISO 15693 standard. The complete system consists of the transponder, reader and a PC. This paper focusses on the development of such a state of the art passive RFID transponder to monitor the wellness of the silicone breast implants periodically in order to detect leakage in the same.

A new, small, and optimized for low power processor core named SIRIUS has been developed, simulated, synthesized to a netlist and verified. From this netlist, containing only primitives like gates and flip-flops, a mapping to an ASIC - or FPGA technology can easily be done with existing synthesizer tools, allowing very complex SOC designs with several blocks. Emulation via FPGA can be done on already simple setups and cheap hardware because of the small core size. The performance is estimated 50 MIPS on Cyclone II FPGA and about 100 MIPS on a 0.35 CMOS 5M2P technology with 4197 primitives used for the core, including a 16 x 16 multiplier. An example design of the ASIC for an electronic ePille device currently in development is shown.
Remote measurement of the physiology, so-called biotelemetry, is a key technology in the modern veterinary medicine. The usage of wireless implants has less impact on the behavior of animals than manual measurement methods and cause less disturbance than wired devices. But, common biotelemetry still uses proprietary communication and power concepts focused on small systems with one animal. Therefore, the University of Applied Sciences Offenburg is developing a low-cost RFID system called muTrans1, which is able to measure ECG, pressure, temperature, oxygen saturation and activity. The muTrans uses an own RFID sensor transponder and standardized commercial components and combines them to a scalable RFID system able to build-up RFID sensor networks with a nearly unlimited size.
Im Institut für angewandte Forschung (IAF) der FH Offenburg wird derzeit eine Chipkarte entwickelt, mit der Temperaturzeitreihen über längere Zeiträume aufgezeichnet werden können. Die zur Datenerfassung erforderlichen Systemkomponenten sind auf nur einem Halbleiterchip zusammengefaßt, wodurch sich bei großen Produktionsstückzahlen ein sehr niedriger Herstellpreis erzielen läßt. Die 'Thermologger' genannte Chipkarte kann zudem mit Standard-Chipkartenlesern und einer dedizierten Software auf jedem PC konfiguriert, gelesen und ausgewertet werden.
