Integrable Autonomous Devices for WSNs

摘要

We here present an energy harvesting system for low power sensor applications. The system is a dual band architecture able to capture the largest amount of EM radiation available in the urban environment and to provide an autonomous device potentially with infinitive cycle of use. The device is tuned to receive both GSM and Wi-Fi frequencies and a power battery loading circuitry is available on board to guarantee the required energy for the autonomous sensor to work. The whole system, designed using a discrete board, has been also conceived in order to be completely integrated in a standard CMOS technology.
