[Invited Talk] A Wireless Self-powered Sensor with Ambient Energy Sources
Takakuni Douseki (Ritsumeikan Univ.) SDM2011-78 ICD2011-46
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 sensor system that runs on small ambient energy sources, such as the light, kinetic, and thermal energy sources around us. First, we describe importance of power management technology for wireless self-powered systems. 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, an automatic switch with an LED as a power source, and a urinary incontinence sensor with a urine-activated battery. Finally, we show that a new application-oriented system design method that considers three key design factors, that is energy generation, energy conversion, and energy dissipation and application, is required for future wireless self-powered systems.
