Motor-less vacuum pumps, also without need for compressed air or lubricants, utilize 50 μm thick dielectric elastomer silicone films

https://www.eurekalert.org/news-releases/1124978 "film moves creating motion (pulsing, vibrating, or undulating) adjusted by varying applied voltage... integrable into compact geometries like smartphones,,, no expensive/ scarce materials like copper/ rare earth elements... very quiet, highly energy-efficient, ideal for cleanrooms/ sterile medical settings... automotive engineering/ manufacturing, medical technology, laboratory research, robotic grippers, industrial packaging machinery"

Miniature, lightweight and energy efficient pumps and valves based on motion of dielectric elastomeric thin-film silicone

https://www.eurekalert.org/news-releases/1076700 "no need for compressed air, motors, lubricants, copper, rare earths... 400X less energy, silent, cleanroom-compatible, can be continuously controlled while operating... can pull vacuum down to 300 mb pressure, deliver exact liquid quantities, act as stepless switches... silicone films (flexible electrically conducting layer printed onto each side) moved applying a small electrical voltage... self-sensing/ reporting... brake boosters, surgical suction, pharmaceutical/ biotech/ foods (freeze drying, sealing, distillation), robot grippers" Related: High mechanical properties and chemical recovery: a new supramolecular elastomer synergistically enabled by boron-based dynamic bonds https://www.eurekalert.org/news-releases/1100224

Engineers create artificial cilia at the microscale

https://techxplore.com/news/2023-09-artificial-cilia-microscale.html "paramecia move 10X own length/ second, cilia also move fluid... clear away mucus in lungs... magnetized carbonyl iron cilia work collectively like a wave by slowly moving magnet near them altering magnetic field control... cilia rows attached along sides of flat plastic base and set on top paramagnetic material cylinder... continuous wavelike action by continuously rolling magnet distorted field lines allowed each cilia to bend forward individually and snap back into place... useful to pump fluids" Related: HKUST develops world's first bio-inspired artificial cilia system https://www.eurekalert.org/news-releases/1123779
