●  Health risks associated with hot climate during labor and sports are increasing. 
●  However, there are no effective bio-sensing devices to predict or judge such personal risk.
●  We need to develop an accurate and simple device evaluating deep body temperature for this purpose.

●  We need to develop an accurate and simple device evaluating deep body temperature for this purpose.

●  We have developed devices monitoring deep body temperature on fields.
●  The device provides accurate data with less influence of sweating, consciousness level, and physical activity, etc.
●  Collecting continuous personal data with BLE and/or Wifi device.

●  The ear-piece sensor detects tympanic temperature, reflecting well deep body temperature (rectal temperature). 
●  The device provides accuracy and repeatability, verified by physiological experiments.
●  In the future, we will develop a system analyzing personal log and mass data.
