A stretchable light-emitting device that operates at low voltages and is safe for human skin, developed by researchers at Nanjing University, could one day provide runners and others with a convenient alternative to a stopwatch or cellphone, allowing them to check their running times with a flick of the wrist.
Alternating-current electroluminescent (ACEL) displays currently exist that can be stuck like a temporary tattoo onto skin and other surfaces. However, these displays require relatively high voltages to achieve sufficient brightness, which can create safety concerns. The Nanjing team wanted to develop an ACEL display that could operate at lower voltages and thus be safer for humans to wear on their skin.
A stretchable…READ MORE
