Abstract (in Japanese) (See Japanese page) 
(in English) In the era of sensor network, there will be a stronger demand for short-range wireless systems to connect things to the network. For such equipment, maintenance-free systems without a replacement of battery are desired. We describe a wireless self-powered system that runs on small green energy sources, such as the light, kinetic, and thermal energy sources around us. First, we review wireless self-powered systems from a standpoint of the key design factors: energy generation, energy conversion, and energy dissipation. Then, we discuss three wireless self-powered systems that we have recently developed: a voice receiver with a spherical Si solar cell for a white-LED-light transmission system, a urinary incontinence sensor with a urine-activated battery, and smart scales with a micro-power generator. Finally, we show that a new system design method that considers all three design factors and application is required for future wireless self-powered systems.
