Chairless exoskeleton to solve long-standing problem The Chairless Chair is a new innovation for relieving strain and fatigue from excessive standing during long work shifts. The entire construct is lightweight, easy to put on, and hardly noticeable when walking. Operating a switch on the strap turns the flexible construct into a stable seat. Two small FAULHABER DC motors activate a stop valve in the hydraulic elements of the shock absorbers, locking the support into the seated position.

Top Tech Tip: How specialized coatings can make mechanical parts harder for extreme industrial applications Although bearings, gears, rollers, and other precision components are generally made of hardened steel or metal alloys, those used in high-load applications still can fail due to excessive wear, surface fatigue, pitting, galling, and corrosion. To address this problem, product engineers and component manufacturers often turn to specialized PVD (physical vapor deposition) coatings that can further harden the surface of these parts. Oerlikon Balzers provides solid solutions.
