Low temperature 3D step-motor using piezo ceramics. Intended for Scanning Probe Microscopy at low temperatures.
A double diaphragm solution for the small thermostatic expansion valves in order to improve the lifetime of the valves used in systems with the new refrigerants which needs typically 50% higher pressure.
A couple of concepts on how to make a valve or pump or compressor using an Electro-Active Polymer.
