A golfer stands in the dreaded sand trap, carefully considering how to balance his weight as he eyes the ball. He takes a few practice swings. If he swings too deeply, he’ll hit the ground and lose another stroke. It’s a tough shot, but he swings without hesitation. Embedded in his club are microelectromechanical system (MEMS) devices—tiny machines with elements about the thickness of a human hair. These devices aren’t going to swing the club for him, but he’s been using them to analyze his swing and practice this shot. Maybe this time he’ll make it.

The wild popularity of smartphones and wearables has been driving down the cost of MEMS devices, including accelerometers, gyroscopes, magnetometers, and pressure sensors. These minuscule chips help to count steps, track calories burned, and monitor heart rate. Such data are useful, sure, but while these devices may nudge users to be more active, they don’t actually improve a swing, a punch, or a kick. To do so means moving sensors off the wrist and into sports gear—and that’s quickly happening. Indeed, you can now buy sensor-based equipment that can boost your performance, not only for golf but also for tennis, baseball, boxing, and soccer.

Adhesives Gain Popularity for Wearable Devices

Adhesive formulations help with challenging assembly of wearables and medical sensors

3 min read

A major challenge in wearable device assembly is to maximize the reliability of embedded circuits while keeping the package thin and flexible.

Master Bond adhesive formulations provide solutions for challenging assembly applications in manufacturing electronic wearable devices. Product formulations include epoxies, silicones, epoxy-polyurethane hybrids, cyanoacrylates, and UV curing compounds.

There are some fundamental things to consider when deciding what is the right adhesive for the assembly of electronic wearable devices. Miniaturization of devices, and the need to meet critical performance specifications with multiple substrates, require an analysis of which chemical composition is most suitable to satisfy the required parameters.

These preliminary decisions are often predicated on the tradeoffs between different adhesive chemistries. They may vary widely, and in many cases are essential in achieving the needed goals in adhering parts and surfaces properly.
