A Digitized Approach to the 3-Omega Method of Thermal Conductivity Testing

C-Therm is teaming up with the University of New Brunswick to develop a highly digitized implementation of the 3-omega method for thermal conductivity measurements of thin films, such as those employed to manage heat in electric vehicle (EV) batteries. In contrast with traditional transient hot-wire techniques, the 3-omega method operates in the frequency domain, allowing measurement times to be substantially reduced. The penetration depth of the measurement can also be controlled by changing the applied frequency, which is particularly important when performing measurements on layered thin films used in EV batteries. A deeper understanding of the thermal properties of these films will enable the development of safer and more efficient battery solutions for clean transportation technologies.
