Abstract
In this paper a proof of concept of ultra-low power Eddy-Current Displacement Sensor (EDCS) is presented. Measurements carried out on the realized prototype, show that the sensor has a resolution up to 6 µm, with a power consumption of 28 µW. The ultra-low power consumption of the sensor could pave the road towards the realization of a new generation of smart wireless displacement and proximity sensors able to gather the needed energy directly from the environment where they operate thanks to the introduction of energy harvesting-based devices.
