Octopus-inspired wearable sensor

Wearable electronics that adhere to skin are an emerging trend in health sensor technology for their ability to monitor a variety of human activities, from heart rate to step count. But finding the best way to stick a device to the body has been a challenge. Now, a team of researchers reports the development of a graphene-based adhesive biosensor inspired by octopus "suckers." They report their findings in ACS Applied Materials & Interfaces.
