‘Electronic tattoos’: Could they be the future of wearables?

Japanese researchers have pushed the boundaries even further when it comes to flexible electronics for wearable medical devices. They say they used a household inkjet printer without soldering to produce 750 nm–thin elastomeric sheets that feel like an “electronic tattoo”

The result of the Waseda University researchers’ work was ultrathin stick-on electronic devices using elastomeric “nanosheet” film. The manufacturing process, they say, has ease of production along with high elasticity and flexibility.

Flexibility, in fact, was 50 times better than what has previously been achieved with polymer nanosheets, according to the Waseda University research team. They envision human-machine interfaces and sensors in the form of electronic tattoos.

They published their work Feb. 1 in the Journal of Materials Chemistry C online edition.
