Harnessing the transverse electrostatic force (TEF) to create a new type of lightweight, magnet-free motor

"converts electrical energy into mechanical motion using ferroelectric fluids... amplifies TEF, which acts perpendicularly to applied electric field,,, ferroelectric nematic liquid crystal mixture combines free-flowing liquid attribute with spontaneous polarization (ability to retain internal electric dipole)... dielectric constant generating stress exceeding 1,000 N/m², achieved at few tens of V (was 10 kV)... future: motor made entirely of plastic, eliminating need for magnets/ rare-earths... compact, energy-efficient actuators/ motors"
