Scientists unveiled a portable technology tool similar to Band-Aid, capable of monitoring heart rate, breathing and movement without batteries, chips or wires.
Professor Zhenan Bao and her team developed the device, which sticks to human skin like a Band-Aid. The device measures how a person’s skin contracts and stretches. It then sends the wireless information to a receiver that is clipped onto the wearer’s clothes. Based on these readings, researchers were able to monitor heart rate, breathing, and leg and arm movements.
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 transmit information, BodyNET uses Bluetooth technology to send information to a nearby smartphone or wireless device.
