Thermoelectric generator – thermally sprayed

Thermally sprayed thermoelectric generator

Concept for a TEG, first approaches by AIST, Tsukuba, Japan, 2008
State-of-the-art
- sintering
- Spark Plasma Sintering (SPS)
- assembly
- rare, expensive, toxic for the health and the environment
Advantage of thermal spraying
- flexibility in shape and size
- large designs
- no assembly necessary
- economically advantageous
- non-toxic materials
Material requirements
- high Seebeck coefficient
- low thermal conductivity
- high electrical conductivity
