Paper Trails

Researchers have developed a cheap and disposable diagnostic tool powered only by your fingertips. The user taps the triboelectric generator on the bottom of the self-powered paper-based electrochemical device (SPED), and electricity from the tips of the fingers is accumulated in a potentiostat. The user places a fingerprick blood sample on top of the testing region, and a measurement of different analytes, such as glucose or lactic acid, is provided in under 30 seconds. The team envisions the test being used for diagnostics in low-resource settings or by military personnel deployed in remote locations.
