Measuring the thermal conductivity of small samples, such as thin-films or small volume liquids, can be incredibly challenging or impossible using macroscale approaches.

An electro-thermal method of thermal measurement called the 3ω method, involving a micro-fabricated resistance thermometer, has been established at UC. This has proven to be a very versatile and interesting technique. This talk will discuss how this technique has been used to measure two nano-particle based materials, and also how it is being developed into an interesting micro-fluidic flow sensor with future potential to measure the thermal transfer function of liquid flowing in a microfluidic channel.
