A fiber-optic powered wireless sensor module made on elastomeric substrate for wearable sensors

We demonstrate an integrated sensor module that combines a photonic nano-porous sensor and a bias-free optical powered RF transducer. The sensor signal is encoded in the RF frequency ready for transmission. The entire sensor module does not include battery and is constructed with the flexible and biocompatible elastomeric polymer, PDMS. This technology holds promise for wearable sensors.
