Experiences of designing micropower wireless devices

We introduce our experiences of designing intelligent wireless devices with mean power consumption far below one milliwatt. An example is a configurable platform offering ultra low power implementation of wireless low-bit-rate devices such as small sensors, tags and actuators. Its versatility is based on configurability, expandability and modularity, giving a basis for the development of various applications. Among the covered topics are also embedded processing platforms supporting ultra low power implementations, clock oscillators, communication parts, sensors and sensor electronics, and considerations of applying parasitic power supplies.
