Smartphone screens are effective sensors for soil & water contamination: Research says.
Researchers from the University of Cambridge say the touchscreen technology used behind smartphones could be effective sensors for soil & water contamination. They demonstrated how a typical smartphone touch screen can detect ionic contaminants in soil or drinking water by dropping liquid samples on the screen. This discovery could lead to the expansion of touchscreen technology in many sensing applications, including for biosensing or medical diagnostics, right from the phone in your pocket. The smartphone is everywhere, so touch screen technology. The touchscreen contained a grid of electrodes. When a…
