![]() ![]() Since wrist or belt-based devices can only measure so much about the body from outside it, many of these bodily functions, like sleep and sex, can only be dubiously inferred from the accelerometers and other sensors that are contained in activity trackers and health devices. There are sensors to monitor your physical activity (steps and the like), heart rate, galvanic skin response, skin temperature, blood pressure (it requires a small cuff), body glucose level (in contact lenses, no less), sexual performance (the Passion app), and sleep. The eSense Skin Response applies a very small, safe and unnoticeable electrical voltage and resulting electrical current to the skin. Apple was smart to announce the HealthKit app standards before the device, and to partner informally with a health-care organization, the Mayo Clinic, that is exploring health applications of the watch and the iPhone.īut Apple's sensors for health functions are far from the only ones available in the Internet of Things pantheon. Skin response Skin response, also known as galvanic skin response (GSR), electrodermal response (EDR) or skin conductance (SC) is a measurement method based on bio-electrical properties of the skin. Apple Inc.'s announcement yesterday of the new Apple Watch with various health sensors and functions prompted me to think about what the heck we are going to do with all the different sensors we will soon have at our disposal. ![]()
