Abstract : Intra-ocular pressure sensors embedded in contact lenses will be of great benefit to long-term treatments of glaucoma. This paper focuses on the resonant type of this kind of sensor and proposes a minimal power consuming conditioning. The system is based on the harmonic oscillator principle and uses very few discrete components to realize a proof of concept. After the description of the eye-care professionals identified needs, we present the sensing principle, and give details on the realized circuit. Brief results are given with signal capture from a prototype to validate the concept.
