VivaLnk is the first company to commercialize eSkin technology, with Google being their first customer in 2014. Â eSkin is a circuit board that is as thin as your skin. It’s comfortable to wear, breathable, and non-invasive and can be used as a platform for sensor integration and data services. Based in Silicon Valley Vivalnk is launching Fever Scout, a soft, wearable, stick-on thermometer that continuously monitors a wearer’s temperature, sharing data with any smartphone via Bluetooth or the cloud. The device can be worn over night and alert a caretaker of a higher fever providing peace of mind.
