| Tiivistelmä (eng): | Implanting medical sensor devices under skin improves the quality of the acquired measurement results, and can greatly increase the comfort for the patient in prolonged measurement. Design of such complex devices and related systems benefits from using a dedicated development platform that represents the functionalities and associated challenges. This work presents the design, implementation and verified performance of a modular platform that can be used in demonstration, development and testing of various functionalities of wireless medical sensor implants. The system is constructed using discrete components and consists of five inter connectable modules, each representing a specfic function of the sensor implant system: bio potential measurement front-end module, wireless communication front-end module, clock and power management module, control logic module and external reader module. The implemented system has measurement front-end with an ENOB of 9 bits and configurable structure for the needs of various bio potentials. Wireless data transfer operates at 840-960 MHz with supported data rate up to 640 kbps. The system demonstrates dual carrier operation for separating the power and data transfers. Power can be harvested and clock extracted from 6.75 MHz or 865 MHz radio signals, both radio signals can be generated by the external reader. Control logic is provided with a high-end FPGA evaluation board. The completed platform can be used for developing and testing aspects for novel implanted devices, such as different radio communication schemes, radio antenna options, or controls and algorithms in digital logic. |
