Cornell University researchers perfected a way to monitor vital signs that doesn’t require skin contact. Their technique relies on small radio frequency identification (RFID) sensors that can pick up heartbeats, chest movements and even blood pressure, and can keep track of multiple patients at once. The technology could be useful in hospitals where round-the-clock supervision is key. Near-field coherent sensing (NCS) opens up new opportunities for vital sign monitoring with accuracy, comfort, convenience and low cost.
