Patent number: 11874184Abstract: In one general aspect, a composite foam comprises a non-layered mixture of a polymeric foam with a plurality of voids; and a plurality of conductive fillers disposed in the polymeric foam. The conductive fillers are disposed in an even manner from outer surface to outer surface. In some implementations, the conductive fillers are up to 25% by weight of the composite foam. In some implementations, the composite foam may be used as padding. In some implementations, the composite foam may be used as a strain gauge. In some implementations, the foam may be in contact with a voltage detector.Type: GrantFiled: May 9, 2022Date of Patent: January 16, 2024Assignee: Nano Composite Products, Inc.Inventors: Aaron Jake Merrell, David T.

Patent number: 10658567Abstract: In one general aspect, an apparatus comprises a material including a non-layered mixture of an polymeric foam with a plurality of voids; and a plurality of conductive fillers disposed in the polymeric foam. The apparatus may produce an electrical response to deformation and, thus, function as a strain gauge. The electrical response may be a decrease in electrical resistance. The electrical response may be an electric potential generated. The conductive fillers may include conductive nanoparticles and/or conductive stabilizers. In another general aspect, a method of measuring compression strain includes detecting, along a first axis, an electrical response generated in response to an impact to a uniform composite material that includes conductive fillers and voids disposed throughout an elastomeric polymer, and determining a deformation of the impact based on the electrical response. The impact may be along a second axis different from the first axis.Type: GrantFiled: April 15, 2019Date of Patent: May 19, 2020Assignee: NANO COMPOSITE PRODUCTS, INC.Inventors: Aaron Jake Merrell, David T.
