Engineers at Stanford University and at Georgia Institute of Technology have created a small, autonomous device with a stretchable/flexible sensor that can be adhered to the skin of cancer-bearing mice to measure the changing size of tumors below. The team claims that the noninvasive, battery-operated FAST (Flexible Autonomous Sensor measuring Tumors) device is sensitive to 10 micrometers and can send results to a smartphone app wirelessly, in real time.
