Abstract :
A wireless method is proposed to read-out a pressure sensor without active electronics in the implant. This passive approach is based on L-C-resonance. It reduces the implant size and improves its long term use since there are no batteries involved. Here, the method is used to measure the intraocular pressure but it is also effective whenever a capacitive output is to be monitored with the smallest possible telemeter size
