Biosensor ‘bandage’ collects and analyzes sweat
Like other biofluids, sweat contains a wealth of information about what’s going on inside the body. However, collecting the fluid for analysis, usually by dripping or absorbing it from the skin’s surface, can be time-consuming and messy. Now, researchers have developed a bandage-like biosensor that both collects and — in conjunction with a smart phone — analyzes sweat. The device could someday help diagnose diseases.
