At this year's MD&M West show, lots of material suppliers talked about new formulations for wearables and things that stick to the skin, whether it's adhesives, wound dressings, skin patches and other drug delivery devices, or medical electronics of various kinds.
Suppliers are developing more skin-sensitive materials and processes for all types of wearable medical devices. At the show, I also heard about the continuing trends in tougher, more cost-effective materials for disposable devices, especially devices using various methods for drug delivery, as well as plastics that resist sterilization and disinfectants for reusable devices.

Covestro, the former Bayer MaterialScience, debuted its Baymedix FP505 prepolymer, which creates aliphatic foams with excellent fluid absorption and retention properties, Bentley Mah, senior technical sales specialist, told Design News. The foams take up fluid well and retain it so it doesn't soak the wound, and they don't turn yellow with age.
