The traditional MEMS-based IOP sensors have a capacitor based on opaque and rigid structures, which limit the field of view in patients. In this paper, a flexible IOP sensor using transparent graphene is presented. This novel wireless sensor is composed of graphene as a capacitor in series with a copper coil, which forms a LC tank resonant circuit. The experiment results show that the working resonant frequency is around 302 MHz. The responsivity is 160 kHz/mmHg and sensitivity is 507 ppm/mmHg.graphene | IOP sensors | wearable sensors | wirelessconference paper10.1109/ICSENS.2016.78087392-s2.0-85010988949https://api.elsevier.com/content/abstract/scopus_id/85010988949
