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.

The grab bag of plastic and rubber materials featured in this new product slideshow are aimed at lighting applications or automotive uses. The rest are for a wide variety of industries, including aerospace, oil & gas, RF and radar, automotive, building materials, and more.
Many of the new adhesives we're featuring in this slideshow are for use in automotive and other transportation applications. The rest of these new products are for a wide variety of applications including aviation, aerospace, electrical motors, electronics, industrial, and semiconductors.
A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
