Wireless powering to implantable biomedical devices is highly desirable due to obviation of batteries or piercing wirings. This paper presents an implantable inductively powered front-end operating at 13.56MHz carrier frequency for biomedical applications, with the capabilities of power transfer, clock extraction and bidirectional command/data communication. The system consideration including the...
This paper presents a fully integrated inductively powered implantable circuits for blood flow measurement, which are embedded within vascular prosthetic grafts for early detection of graft degradation or failure. The ASIC interfaces with micro-fabricated pressure sensors and uses a 13.56MHz carrier frequency for power transfer and command/data communication. A backscatter-modulated passive telemetry...
