A thin, soft stick-on patch that can stretch and move with the skin uses off-the shelf chip-based electronics to continuously track health and wirelessly send updates to your cellphone or computer. The patches stick to the skin like a temporary tattoo and incorporate a unique microfluidic construction with wires folded like origami to allow the patch to bend and flex without being constrained by the rigid electronics components. Researchers say the patches could revolutionize clinical monitoring such as EKG and EEG testing—no bulky wires, pads, or tape required. “We designed this device to monitor human health 24/7, but without interfering with a person’s daily activity,” says Yonggang Huang, professor of civil and environmental engineering and mechanical engineering at Northwestern University . “It is as soft as human skin and can move with your body, but at the same time it has many different monitoring functions. What is very important about this device is it i...
