I’d like to see more of these kind of wearables:
“Kyocera Corporation (President: Goro Yamaguchi) announced that it has developed one of the smallest known optical blood-flow sensors, which measures the volume of blood flow in subcutaneous tissue. With the sensor, Kyocera is researching a variety of mobile health (mHealth) applications such as monitoring stress levels or preventing dehydration, heatstroke and altitude sickness by studying trends or changes in blood-flow volume as alerts for these conditions and developing algorithms for detection.
Leveraging Kyocera’s expertise in miniaturization, the sensor — only 1mm high, 1.6mm long and 3.2mm wide — is designed for use in small devices such as mobile phones and wearable devices. The company will offer sensor module samples starting April 2017, and aims to commercialize the technology as a device by March 2018.
