The BodyNet wearable sensor can be comfortably worn on the skin to track vital signs and transmit the data to an adjacent receiver.
The latest innovation from the team at Stanford headed up by professor Zhenan Bao, the sensor is made up of an elastic, transparent material with a metallic-ink antenna screen-printed on it. Though the antenna can withstand being stretched, the motions weakened its signal—so the team developed a new RFID system able to transmit a strong signal even when being bent.
Currently, the sensor sticker can measure vitals such as respiration and pulse and send the data to a receiver worn on the clothing just above the sensor. However, the team hopes the BodyNet technology could eventually make use of smart clothing with the antennas woven into the fabric to send the data to a nearby device.
