Zwitterionic Polymer Gel‐Based Fully Self‐Healable Ionic Thermoelectric Generators with Pressure‐Activated Electrodes (Adv. Energy Mater. 32/2023)

Dispenser Printed Thermoelectric Energy Generators

Thermoelectric energy generators are attractive as potential energy harvesters for converting waste thermal energy into electrical power. Optimized thermoelectric device designs require 100-200 μm element thicknesses currently unachievable with common manufacturing technologies. This work presents both a unique direct-write dispenser printing technique and novel polymer-composite thermoelectric...

Flexible Sheet-type Thermoelectric Generators for Energy Harvesting

We describe prototype production of sheet-type thermoelectric power generation modules using the printable thermoelectric materials and flexible sheet substrate. By the use of the printed electronics processes, the degree of freedom in designing the size and shape of the modules were improved. The power generation scale of a module has about 60 cm active area reached to sub m W order at a tempe...

Dispenser-printed planar thick-film thermoelectric energy generators

This work presents advancements in dispenser-printed thick film thermoelectric materials for the fabrication of planar and printable thermoelectric energy generators. The thermoelectric properties of the printed thermoelectric materials were measured as a function of temperature. The maximum dimensionless figures of merit (ZTs) at 302 K for the n-type Bi2Te3-epoxy composite and the p-type Sb2Te...
