Latest Patents

Jeunghwan Choi holds a patent titled "System and method for determining a spatial thermal property profile of a sample." This patent describes a sensing system that utilizes three-omega sensing to determine a spatial profile of thermal properties within a sample. The system electrically powers a lossy electrical conductor at various driving frequencies, which results in different penetration depths within the sample. By taking multiple measurements of thermal properties at these different frequencies, the system can average the measurements over differently-sized volumes within the sample. This innovative approach allows for a fit on the multiple measurements of material thermal property versus material geometry. If either the thermal property or geometry is known beforehand, the fit can determine the other.
