Fitbits and similar biometric monitors are great, but it can be a problem. They only work when attached to a wrist.
Samsung sees a market in this. Researchers at the company published an article describing a theoretically commercial way of sticking stretchy wearable devices onto human skin.
The researcher works at the Samsung Advanced Institute of Technology. They claim to have integrated elastic technology with conventional chip processes. The flat device can be stretched up to 30 percent in any direction.
Specifically, they created a biometric device consisting of an expandable OLED screen and a photoplethysmography sensor. During testing, it was glued to the inside of the wrist above the radial artery where it measured and displayed the wearer’s heart rate in real time.
The device was stretched 1,000 times and, according to the researchers, it was able to deliver a pulse signal to a moving wrist 2.4 times stronger than a conventional fixed silicon sensor.
This result, according to the researchers, “proves the feasibility of expanding the technology” with other biometric applications.
Samsung faces a growing market (for related ideas, even products) for wearable devices that sit next to or stick to the skin.
