Muhammad Arsalan, et al., "Implantable intraocular pressure monitoring systems: Design considerations." In 2013 IEEE MTT-S International Microwave Workshop Series on RF and Wireless Technologies for Biomedical and Healthcare Applications (IMWS-BIO), 2013, 1. Design considerations and limitations of implantable Intraocular Pressure Monitoring (IOPM) systems are presented in this paper. Detailed comparison with the state of the art is performed to highlight the benefits and challenges of the proposed design. The system-on-chip, presented here, is battery free and harvests energy from incoming RF

Mohamed Arsalan, et al., "A 5.2 GHz, 0.5 mW RF powered wireless sensor with dual on-chip antennas for implantable intraocular pressure monitoring." In 2013 IEEE MTT-S International Microwave Symposium Digest (MTT), 2013, 1. For the first time a single chip implantable wireless sensor system for Intraocular Pressure Monitoring (IOPM) is presented. This system-on-chip (SoC) is battery-free and harvests energy from incoming RF signals. The chip is self-contained and does not require external components or bond wires to function. This 1.4mm 3 SoC has separate 2.4GHz-transmit and 5.2GHz-receive
