Abstract

A high-performance, wearable thermoelectric generator (TEG) was fabricated with a highly aligned carbon nanotube (CNT) sheet. The aligned CNT sheet exhibits extraordinary electrical conductivity compared to disordered CNT sheets and also can be directly fabricated as a continuous TEG without metal electrode interconnects. This provides a significant reduction in contact resistance between TE legs and electrodes compared to traditional TEGs, resulting in higher power output. In addition, the continuity of the module without any disconnected parts provides high degrees of mechanical stability and durability. Finally, this robust and scalable approach to flexible TEG fabrication paves the way for CNT applications in lightweight, flexible, and wearable electronics.

Macroscopically aligned carbon nanotubes for flexible and high-temperature electronics, optoelectronics, and thermoelectrics

Journal Article Gao, Weilu ; Komatsu, Natsumi ; Taylor, Lauren W. ; ... - Journal of Physics. D, Applied Physics

The remarkable flexibility, stable chemical structure, and extraordinary thermal, electrical, and optical properties of carbon nanotubes (CNTs) are promising for a variety of applications in flexible and/or high-temperature electronics, optoelectronics, and thermoelectrics, including wearables, refractory photonics, and waste heat harvesting. However, the long-standing problem in the preparation of CNT ensembles is to maintain the extraordinary properties of individual CNTs on a macroscopic scale; the polydispersity and randomness remain two main challenges. In this topical review, we will discuss three ways of creating wafer-scale aligned CNTs: direct growth of aligned CNTs by chemical vapor deposition, production of ultrahigh- conductivity CNT fibersmore »« less

Carbon nanotube thermoelectric devices by direct printing: Toward wearable energy converters

Journal Article Lee, Hye Ryoung ; Furukawa, Naoki ; Ricco, Antonio J. ; ... - Applied Physics Letters

Thermoelectric devices convert thermal energy to electrical energy and are particularly well-suited for energy harvesting from waste heat. Even as the number of electronic devices used in daily life proliferates, technical advances diminish the average power such devices require to perform a given function. Here, localized thermal gradients that abound in our living environments, despite having modest energy densities, are therefore becoming increasingly viable and attractive to power such devices. With this motivation, we report the design, fabrication, and characterization of single-wall carbon nanotube thermoelectric devices (CNT-TDs) on flexible polyimide substrates as a basis for wearable energy converters.

Lightweight wearable thermoelectric cooler with rationally designed flexible heatsink consisting of phase-change material/graphite/silicone elastomer

Journal Article Choi, Jaeyoo ; Dun, Chaochao ; Forsythe, Carlos ; ... - Journal of Materials Chemistry. A

Here, we propose a lightweight wearable thermoelectric (TE) cooler with a rationally designed flexible heatsink. Heatsinks are commonly designed for use with stationary applications, and are consequently rigid and heavy. These traditional heatsinks are incompatible with wearable applications, which must be durable, mechanically flexible, and lightweight while maintaining performance. This paper presents a flexible heatsink based on a ternary composite of silicone elastomer, phase-change material, and graphite powder; this combination is needed to achieve high flexibility and durability as well as the optimum heat capacity and thermal conductivity. Those factors are key requirements for a heatsink to optimize the coolingmore »« less

Inkjet Printing of Single-Crystalline Bi₂Te₃ Thermoelectric Nanowire Networks

Journal Article Chen, Bolin ; Das, Suprem R. ; Zheng, Wei ; ... - Advanced Electronic Materials

Large-scale and low-cost fabrication techniques are needed to commercialize highly efficient, nanomaterial-based thermoelectric generators (TEGs) for use in small-scale, flexible applications (e.g., wearable energy harvesters). This study presents the first demonstration of inkjet-printed networks of phase-pure, single-crystalline Bi₂Te₃ thermoelectric nanowires (BTNWs) that are amenable to large-scale production. The BTNWs are synthesized via chemical batch processing and formulated into a jettable ink that is printed onto glass substrates and subsequently annealed in nitrogen and forming gas environments. The inkjet-printed BTNWs annealed in forming gas provide the most favorable results with comparable thermoelectric performances to bulk Bi₂Te₃ materials (Seebeck coefficient up tomore »« less

Electrokinetics of scalable, electric-field-assisted fabrication of vertically aligned carbon-nanotube/polymer composites

Journal Article Castellano, Richard J. ; Akin, Cevat ; Giraldo, Gabriel ; ... - Journal of Applied Physics

Composite thin films incorporating vertically aligned carbon nanotubes (VACNTs) offer promise for a variety of applications where the vertical alignment of the CNTs is critical to meet performance requirements, e.g., highly permeable membranes, thermal interfaces, dry adhesives, and films with anisotropic electrical conductivity. However, current VACNT fabrication techniques are complex and difficult to scale up. In this paper, we describe a solution-based, electric-field-assisted approach as a costeffective and scalable method to produce large-area VACNT composites. Multiwall-carbon nanotubes are dispersed in a polymeric matrix, aligned with an alternating-current (AC) electric field, and electrophoretically concentrated to one side of the thin filmmore »« less
