A research team at the Korea Advanced Institute of Science and Technology (KAIST) has developed tattoo ink made of liquid metal and carbon nanotubes that can work as a bioelectrode. This technology could translate to a tattoo that can function as a health-monitoring device.

Medtronic plc inked an agreement to combine its patient care technologies with a wearable, remote monitoring platform developed by Pasadena, Calif.-based Rockley Photonics Inc. The Bioptx contains compact, photonics-based sensors inside a wristband to monitor a range of biomarkers beyond standard blood pressure, heart rate, pulse oximetry and glucose levels, making Rockley and Medtronic’s development partnership, said Rockley Chair and CEO Andrew Rickman, “a terrific match.”

The FDA granted Adherium Ltd. 510(k) clearance for its next-generation Hailie sensor that connects with Glaxosmithkline plc’s Ellipta inhaler to enable monitoring of medication use for asthma and chronic obstructive pulmonary disorder (COPD).
