The idea behind the new microPEM TackSert pin is to eliminate threaded hardware in small, compact electronics, like credit card readers, SIM card ejectors, and the growing class of wearables, increasingly important as electronics get smaller.

Innovative designs and versatile materials

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. Here are my others:

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.
We've found an amazing variety of robot hands & arms in medicine, space, and service robots, as well as R&D and assembly. Some are based on industrial designs modified for speed or dexterity, while others more closely emulate human movements, as well as human size and shape.
To give engineers a better idea of the range of resins and polymers available as alternatives to other materials, this Technology Roundup presents several articles on engineering plastics that can do the job.
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team 100 to make (about $161 US).
A tiny humanoid robot has safely piloted a small plane all the way from cold start to takeoff, landing and coming to a full stop on the plane's designated runway. Yes, it happened in a pilot training simulation -- but the research team isn't far away from doing it in the real world.
