A Robust System for Thermoelectric Device Characterization
IEEE Transactions on Instrumentation and Measurement, 2021Due to the large reduction in fossil fuel reservoirs, the consequent cost increase of deepwater extraction, and the emission of pollutants, there is a constant search for alternative ways to obtain clean energy at a lower cost. Among those sources, we focus on the energy produced by thermoelectric materials.

Efficiency of Thermoelectric Devices
American Journal of Physics, 1961The known expressions for various efficiencies of thermoelectric energy converters can be so modified that the Carnot efficiency ηc of the ideal heat engine cycle appears as one of two significant parameters. The other parameter ZT (Z = figure of merit, T = hot spot temperature in °K) is a significant characteristic of the thermoelectric material used

Efficient thermoelectric cooling for mobile devices
2017 IEEE/ACM International Symposium on Low Power Electronics and Design (ISLPED), 2017Mobile apps suffer large performance degradation when the underlying processors are throttled to cool down the devices. Fans or heat sinks are not a viable option for mobile devices, thus calling for a new portable cooling solution. Thermoelectric coolers are scalable and controllable cooling devices that can be embedded into mobile devices on the chip
