Faces made of living skin make robots smile
Jun 2024, BBC News
Tokyo University makes Face on a Chip (see the above image) - The trick the team employed was to use a special collagen gel for adhesion, which is naturally viscous so difficult to feed into the minuscule perforations. But using a common technique for plastic adhesion called plasma treatment, they managed to coax the collagen into the fine structures of the perforations while also holding the skin close to the surface in question.
Something like a face-on-a-chip could be useful in research into skin aging, cosmetics, surgical procedures, plastic surgery and more. (Follow the link and watch it move.)

Scientists create 'living bioelectronics' that can sense and heal skin
May 2024, phys.org
They made a new kind of bioelectronics that uses not just the electronics and a soft layer to make them less irritating to the body, but now a layer of living cells made of a gel from tapioca starch and gelatin, with S. epidermidis microbes tucked in. S. epidermidis microbes secrete compounds that reduce inflammation.

Rewritable, recyclable 'smart skin' monitors biological signals on demand
May 2024, phys.org
The researchers made an adhesive composite with molecules called polyimide powders that add strength and heat resistance and amine-based ethoxylated polyethylenimine - a type of polymer that can modify conductive materials - dispersed in a silicone elastomer (rubber) to monitor the pH value, glucose and lactate concentrations in sweat as well as detecting via finger prick blood draws. It can also be reprogrammed to monitor heart rate, nerve performance and sweat glucose concentrations in real time.
