dc.description.abstract Microsystems that harvest ambient power for their operation have been present in RFID technology and implantable medical devices (IMDs) for couple of decades. With the recent applications under the framework of the Internet of Thing (IoT) and with miniaturization of implantable devices interest in these devices has significantly grown. Two of the critical subjects in the passive devices technology are wireless power transfer (WPT) and data link. The focus of this work is on two distinct applications: design of wireless power transfer for IMDs and backscatter-based tag-to-tag (BBTT) communication system. Our goal in the design of WPT to IMDs is to deliver maximum power through optimization of the inductive coupling link without violating the regulation of the maximum tissue exposure to the electromagnetic (EM) field radiation. The adaptive transmitting coil array is investigated to reduce specific absorption rate (SAR) on the tissue and mitigate coil misalignment problem. Two analysis methods, traditional quasi-static method and full-wave analysis method, are discussed and combined to optimize the inductive link. BBTT devices communicate by backscattering existing external excitation field, which can come from multiple sources, e.g., dedicated exciters, WiFi access points, TV towers, cell phone towers. This is contrary to the traditional backscattering devices like RFID tags which are designed to communicate directly with an active reader leading to a centralized network focused on the reader. Focus of this work is on design of the analog front end (AFE) and the backscatter modulator (BM), which determine BBTT communication range and link robustness. We propose novel solutions to optimize architecture and parameters of the AFE and BM circuits for the unique BBTT link. Design of the BBTT prototype and the experimental results are presented. en_US
