What Are the Size Limitations of Thermoelectric Generators?

Click For Summary
SUMMARY

The size limitations of thermoelectric generators (TEGs) are influenced by various factors, including manufacturing challenges and physical constraints. Specifically, as Peltier elements decrease in size, they become increasingly difficult to produce. Micropelt is noted for producing some of the smallest Peltier generators, where the thickness is primarily determined by the silicon substrate. Additionally, constraints such as atomic layers and gravitational effects play a significant role in defining the minimum and maximum sizes of TEG modules.

PREREQUISITES
  • Understanding of thermoelectric principles
  • Familiarity with Peltier elements and their applications
  • Knowledge of materials science, particularly regarding silicon substrates
  • Awareness of manufacturing processes for micro-scale devices
NEXT STEPS
  • Research the manufacturing techniques for micro-scale Peltier elements
  • Explore the physical constraints affecting thermoelectric generator design
  • Study the performance characteristics of different thermoelectric materials
  • Investigate applications of thermoelectric generators in various industries
USEFUL FOR

Engineers, researchers, and manufacturers involved in the design and production of thermoelectric generators, as well as those interested in the applications of Peltier elements in technology.

it's a simple question:
is there any limitation to the size of an thermoelectric generator module?
is there any minimum thickness?
thank you in advance

Actually it is not a simple question... There are a number of values that scale with size, and at the far ends there are physical constraints like atomic layers or gravity. When you make Peltier elements small they become very hard to manufacture. These guys probably make the smallest Peltier generators out there: http://www.micropelt.com/products/products.php For those the thickness is dominated by the silicon substrate.
