A team of researchers has developed a new form of electronics known as drawn-on-skin electronics, allowing multifunctional sensors and circuits to be drawn on the skin with an ink pen.

The advance allows for the collection of more precise, motion artifact-free health data, solving the long-standing problem of collecting precise biological data through a wearable device when the subject is in motion.

The drawn-on-skin electronics can be customized to collect different types of information, and it is expected to be especially useful in situations where it’s not possible to access sophisticated equipment.

The electronics are able to track muscle signals, heart rate, temperature, and skin hydration, among other physical data. The researchers also reported that the drawn-on-skin electronics have demonstrated the ability to accelerate healing of wounds.

The drawn-on-skin electronics are comprised of three inks, serving as a conductor, semiconductor, and dielectric.
