A small, autonomous device with a stretchable and flexible sensor that adheres to the skin can measure the changing size of tumors below the surface, a new study with mice shows.
The non-invasive, battery-operated device is sensitive to one-hundredth of a millimeter (10 micrometers) and can beam results to a smartphone app wirelessly in real time with the press of a button.
In practical terms, the researchers say, the device—dubbed FAST for “Flexible Autonomous Sensor measuring Tumors”—represents a wholly new, fast, inexpensive, hands-free, and accurate way to test the efficacy of cancer drugs. On a grander scale, it could lead to promising new directions in cancer treatment. The device is detailed in a paper in Science Advances.
