These painted e-tattoos could be the future of wearable biosensors

Credit: Wanqing Zhang Credit: Wanqing Zhang Scientists at Pennsylvania State University have developed a novel conductive ink that can be painted directly onto the skin in colorful custom designs, turning into a functional electrode for biomonitoring after drying. They described their work in a new paper published in the Proceedings of the National Academy of Sciences (PNAS). As previously reported , epidermal electronics attached to the skin via temporary tattoos (e-tattoos) have been around fo
