Abstract

This article presents the realization of a new energy self-powered sensor node. The wireless node is supplied by 10 μW of electrical power and is able to send three measured values in intervals of 80s. The power supply is carried out with a MEMS-based piezoelectric vibration converter. A specially developed ASIC for this type of generator takes over the energy management. The wireless connection to a base station is established by a microcontroller predestinated for energy autonomous applications in conjunction with a standard IEEE 802.15.4 RF-frontend. The used Route Under MAC wireless protocol is specifically designed for energy-saving operations. The protocol supports the IPv6/6LoWPAN standard whereby multiple sensor nodes can be integrated in a wired network.
