Summary:The wireless sensor network (WSN) is a promising technology to improve the social life cooperating with the robotic technologies like nursing robots, disaster rescue robots, industrial robots, and so on. For such WSN, we propose an architecture of the sensor node with zero standby power consumption. This is accomplished by combining a power transistor cutting the ground line, an electromotive from a sensor for just turning on the power transistor and a conventional battery. The preliminary experiments demonstrate that our proposal can actually activate the sensor node, which stays at the sleep mode with zero power consumption, with a short-time electromotive force generated by the piezoelectric sensor. It is also confirmed that the sensor node activated can establish the wireless communication correctly.
