TEG2-126LDT for Body & Sensor Power Thermoelectric Harvesting Applications!

B1-smal
The TEG2-126LDT is a Low Delta Temperature designed module. Ideally designed for body and micro harvesting applications. Micro Scavenging heat to power “internet of things” is difficult at best. Sensors require battery power which depletes over a short time requiring constant battery changes or charging. Thermoelectric power modules properly designed into a wearable can extend battery life 10 to 100 fold. Scavenging devices require autonomous power to be effective and long lasting without scheduled service appointments to replace batteries, which lose power always at the most inconvenient times. Most require maybe 1V to 2V at 20ma, or less?

The main consideration is how to design a TEG scavenger module to provide the most possible power given so, little the available DT provided in the application.

Primary consideration is not only the TEG module but the methods required to move the maximum amount of available heat which is typically overlooked in most applications. We have become experts at designing the heat removal design. Call us with your application.

The TEG2-126LDT thermoelectric power module is a cost effective scavenger design that provides effective energy harvesting from minimal heat differentials. (Even high heat with low DT’s has the exact same principles).
