ACTUATOR COMPRISING ELECTRICALLY CONDUCTIVE POROUS MATERIAL - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240026865 titled 'ACTUATOR COMPRISING ELECTRICALLY CONDUCTIVE POROUS MATERIAL
Simplified Explanation
The patent application describes an actuator device that includes a housing body and a movable surface, with an enclosed volume region that can expand from an initial volume state to an enlarged volume state. The enclosed volume region contains an electrically conductive porous material, primarily made of carbonaceous material, with a mass density ranging from about 0.5 mg/cc to about 100 mg/cc. The device also includes a first and second electrode to pass an electric current through the porous material. When the electric current is applied, the air within the enclosed volume region expands, causing the movable surface to displace.
- The actuator device comprises a housing body and a movable surface.

Original Abstract Submitted
an actuator device comprises an enclosed volume region defined by a housing body and a movable surface, such that at least a portion of the enclosed volume region is expandable from an initial volume state to an enlarged volume state. an electrically conductive porous material is disposed in the enclosed volume region, wherein the electrically conductive porous material has a mass density of from about 0.5 mg/cc to about 100 mg/cc, and wherein at least about 90% of the electrically conductive porous material is a carbonaceous material. a first electrode and a second electrode are configured to pass an electric current through the electrically conductive porous material. when an electric current is passed through the electrically conductive porous material, air disposed in the enclosed volume region expands and displaces the movable surface. a method of displacing a movable surface in an actuator device is also described.
