Abstract (in Japanese) (See Japanese page) 
(in English) In this report, we describe a power supply system and an energy-saving method of a sensor node in a sensor network. We studied a hybrid type of the solar battery and the lithium-ion battery as a power supply system, and the power management of the event-driven type to make the sensor node activated by the information from the sensor by setting an analog comparator in a program as an energy-saving scheme. As the result, we achieved the sensor node driven without maintenance by the power supply from the hybrid power supply system all day, and the energy-saving of about 43% by the event-driven power management.
