This paper presents a low-power (~10μW) 2.45-GHz wireless sensor platform consisting of a three-axis accelerometer, thermometer and skin conductivity sensor. The sensor is powered wirelessly from a distance of around 3-4m with narrowband 2.45-GHz dual-polarized low power density radiation of around 100μW/cm2. Efficient power management enables the powering function to be independent of the wireless transmission and sensor data gathering. The sensor platform does not require battery replacements, and is intended for low-maintenance assistive technology, elder-care and medical applications.
