  • DIELECTRIC CAPACITOR FORMED OF A DIELECTRIC-COATED ELECTRICALLY CONDUCTIVE POROUS SCAFFOLD FILLED WITH METAL
    Publication number: 20240079183
    Abstract: Novel dielectric capacitor devices include an electrically conductive porous scaffold forming a first conductor, a conformal thin dielectric uniformly coating the pores, and a metal or alloy which fills the conformal dielectric coated pores of the scaffold forming a second conductor. This structure's design provides high surface area for high energy storage and capacitance density as well as high thermal conductivity. The metal or alloy can be a liquid metal and flowed within the device to change the electrical or mechanical properties of the device.

  • Continuous bending-mode elastocaloric cooling/heating flow loop
    Patent number: 11204189
    Abstract: A method of cooling includes providing an elastocaloric material; continuously applying a force on the elastocaloric material to cause a continuous mechanical deformation of the elastocaloric material for a predetermined period of time, such that the continuous mechanical deformation creates a solid-to-solid phase transformation in the elastocaloric material; emitting exothermic latent heat from the elastocaloric material to increase a temperature of the elastocaloric material; removing the force from the elastocaloric material upon expiration of the predetermined period of time; and absorbing endothermic latent heat into the elastocaloric material to decrease the temperature of the elastocaloric material and/or an environment adjacent to the elastocaloric material or an electronic/phononic device, etc.
    Type: Grant
