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.
