Google's life sciences group has developed a health-tracking wristband that an measure pulse, heartbeat rhythm and skin temperature, and also information like light exposure, noise levels. The device, which could be used in clinical trials and drug tests, was developed within the company’s Google X research division. It is not a consumer device, and Google plans to market it as a medical device.

Google will collaborate with academic researchers and drugmakers to test the wristband’s accuracy and seek regulatory clearance to use it in the U.S. and Europe.

For consumers, Google offers health-monitoring smartwatch features in its Android Wear software platform.

Google's life sciences division has already created an experimental contact lens that can read blood sugar levels in diabetics.
