The ultimate glow up: Flexible screens reach record brightness with redesigned electrolyte and electrodes

From a skin patch that changes color to flag abnormal blood sugar to a diver’s sleeve display that stays readable underwater, the need for bright, flexible screens is growing, but no existing technology delivers the combination of simplicity, low power and robustness these applications need. Existing organic light-emitting diodes require complex multilayer structures that are difficult to bend reliably. Light-emitting capacitors are simpler, but they demand hundreds or even thousands of volts, ruling out anything worn on the body.
