Sweat Monitor Could Replace Finger-Prick Blood Tests
People suffering from diabetes and other chronic conditions, finger-prick blood tests can be painful and expensive. A new flexible sensor, developed by researchers at the University of Glascow, can sense changes in a persons sweat. Since sweat contains similar physiological information as a person's blood, sweat monitoring could be a viable alternative to finger-prick blood tests. The sweat monitor is a small patch, about the size of a postage stamp, that can stretch with a person's natural movements without compromising performance. Sensors in the patch measure things such as ammonia, glucose, and urea and then use an RFID transmitter to send the data to the patient's smartphone.
