A new adhesive for wound dressings available in the US is based on the Bayer MaterialScience's Baymedix A polyurethane raw material. The adhesive, designed to be kinder to the skin, is more breathable than silicone and is comparable to them in its ease of removal and its adjustable adhesive strengths and hydroselectivity.

The microPEM pins are so tiny you can barely see them with the naked eye, at least with my eyes unaided by glasses. The sample Penn gives out is so small and lightweight--2 super thin 1.5in diameter disks fastened together--it kept flying out of the pocket in my notebook (not a computer, an actual paper device I use to take notes on). I was also impressed by the many uses of silicone for adhesives, coatings, and other apps: it's a truly versatile material.
Ann--I have used Penn fasteners and can "testify" they really do a great job depending upon the application. The micro-devices are ideal for the applications you mention in your post. I was very surprised at the shear and tensile some designs can tolerate. I'm really sorry I missed the show. Certainly seems like a great experience and I look forward to other posts you make relative to your visit.
Thanks for that input, bobjengr. I've done several posts from that show, as have the rest of us who went.

A lightweight electric urban concept car designed by several European companies weighs only 992 lb without its battery. It would have weighed 26.7 lb more if its windows were made of glass instead of the specially coated LEXAN polycarbonate resin from SABIC Innovative Plastics.
Skylar Tibbits' team in MIT's Self-Assembly Lab is now 4D printing self-assembling shapes made of programmable carbon composites and custom wood grain. The composites are being used in a sport car airfoil, and the wood grain is beautiful.
The NanoSteel Company has produced high-hardness ferrous metal matrix composite (MMC) parts using a new nanosteel powder in a one-step 3D-printing process. Parts are 99.9% dense, crack-free, and with wear resistance comparable to M2 tool steels.
The company that brought you 3D-printed eyeglasses has launched both an improved clear polymer material for 3D printing optical components and a high-speed, precision, 3D-printing process for making small- and medium-sized batches in a few days.
