Recent advances in printable thermoelectric devices: materials, printing techniques, and applications

Abstract

Additive printing as a low-cost and efficient fabrication technique for thermoelectric device is reviewed targeting the application of energy harvesting from human body.

Ink‐Based Additive Nanomanufacturing of Functional Materials for Human‐Integrated Smart Wearables

“…[698,700] For example, inorganic nanomaterials were added into polymers to achieve high thermoelectric performance. [707,708] The main design challenge in a TEG is to maximize the temperature difference across the hot-cold junctions. There are mainly two categories of TEGs, planar TEGs, where the junctions are on the same plane to the substrate, and through-plane TEGs, where the junctions are normal to the substrate.…”

“…[12,701] To create a temperature difference across planar devices that are suitable for harvesting the thermal energy from the human body device configuration such as corrugation, origami, z-scheme folding, and vertical staking have been developed. [695,707] Printing methods such as inkjet printing, aerosol jet printing, DIW, and spray coating have been used to fabricate TEGs. [706,707,709,710] Madan et al demonstrated the DIW of mechanically alloyed (MA) n-type Bi 2 Te 3 composite to fabricate TEGs in a cost-effective and scalable way.…”

[709] MA n-type Bi 2 Te 3 -epoxy composite films (with 1 wt% Se) cured at 350 C delivered a maximum ZT value of 0.31.…”

Printed Thermoelectrics

“…2022, 34, 2108183 where the solute within the deposited ink flows to the outside of the deposited droplet via capillary effects as it dries, causing the inside of the droplet to be thinner, this can cause uneven characteristics within the ink. [28] Films and devices produced via inkjet printing are also very thin (≈0.4-1.6 µm). [29] Dispenser printing (Figure 3d) is a simple process that consists of a syringe that deposits ink onto a substrate through a needle.…”

Development of a schwarzite-based moving bed 3D printed water treatment system for nanoplastic remediation

“…22 The ltration efficiency is improved with the help of increasing surface area of the porous architecture. 23 The porous lters are fabricated by gas foaming, solvent casting/particulate leaching, freeze-drying, and 3D printing [24][25][26][27][28][29] techniques. Among these, 3D printing is the competitive technique due to its numerous advantages, such as its capability to fabricate complex structures, agility to print a wide spectrum of compatible materials, sustainability, and scalability.…”
