A wake-up receiver for online energy harvesting enabled wireless sensor networks

Bdiri, Sadok / Derbel, Faouzi / Kanoun, Olfa


Supplying power-hungry radio receivers with an energy harvester is challenging. A wake-up receiver (WuRx) for wireless sensor networks consumesmuch less power. The introducedWuRx operateswith a modifiedmedium access protocol (MAC), allowing low-energy consumption and practical latency. The sensitivity of the WuRx is optimized with minimally integrated active parts, emphasizing −61 dBm. The idle power consumption of the WuRx reaches down to 7.2 μW and 500 μW during decoding. TheWuRx can handle a 32-bit long pattern at a bit rate of 4 kbit/swithManchester encoding. The design blocks are discussed in this paper. A prototype is realized for evaluation purposes.
