Band-Aid like wearable tech can monitor heart rate
The device, which sticks to human skin like a Band-Aid has been developed by Professor Zhenan Bao and her team. The device measures how a person’s skin contracts and stretches. It then sends the information wirelessly to a receiver which is clipped on the wearer’s clothes. Based on these readings, researches were able to monitor heart-rate, breathing and leg and arm movement.
The device has been named “Body Area Sensor Network” or “Body NET”. It works using the same principals as keycards: radiofrequency identification.
While keyless cards use an antenna inside the card to convey information, the BodyNET uses Bluetooth technology to send the information to a smartphone or wireless device nearby.
