This paper is focused on powering wireless devices (including sensors) with high efficiency circuitry that can harvest ambient WiFi/Bluetooth energy and convert into direct current (dc). Herewith, we introduce a novel circuitry to generate a battery-like voltage from very low incoming RF energy (<;-20 dBm). The new RF energy harvesting front-end is demonstrated to have much better conversion efficiency than state-of-the-art commercial RF harvesting modules, notably for low power levels… CONTINUE READING
