Abstract

Conventionally, people have to go to the place where a measurement instrument for health data is, to obtain health data and the like. Further, even when using a portable measurement instrument, people have to manage data by themselves, thus health data cannot be managed rapidly. According to the invention, a modulating circuit, a demodulating circuit, a logic circuit, a sensor circuit, and an antenna circuit are provided over an insulating substrate, thereby data sensed by the sensor circuit is transmitted wirelessly. According to the invention, health data on the living body (for example a human body) is sensed and can be rapidly detected.
