A new way of generating electrical power by changing the dielectric properties of liquid crystals by mechanical means is described. Such a method and device take advantage of the nature of the liquid crystal as the dielectric material in a capacitor. A broad range of materials, including various liquid crystalline materials, as well as additional mechanisms (flexoelectric polarization) to fully exploit the potential of this mechanism may be realized. Applications of this technology may be useful in wearable personal electric generators as well as in noise damping materials/devices, which not only absorb and dissipate sound, but use it to generate electric power.
