“…To date, many thin-film thermoelectric devices have been fabricated using various film deposition methods such as flash evaporation [12][13][14], sputtering [15][16][17], and electrodeposition [18,19]. In addition, thin-film thermoelectric materials possess favorable features not exhibited by bulk materials.…”

Abstract:To reduce consumption for ambient assisted living (AAL) applications, we propose the design and fabrication of flexible thin-film thermoelectric generators at a low manufacturing cost. The generators were fabricated using a combination of electrodeposition and transfer processes. N-type Bi 2 Te 3 films and p-type Sb 2 Te 3 films were formed on a stainless-steel substrate employing potentiostatic electrodeposition using a nitric acid-based bath, followed by a transfer process. Three types of flexible thin-film thermoelectric generators were fabricated. The open circuit voltage (V oc ) and maximum output power (P max ) were measured by applying a temperature difference between the ends of the generator. The thin-film generators obtained using thermoplastic sheets with epoxy resin exhibited a V oc that was tens of millivolts. In particular, the contact resistance of the thin-film generator decreased when silver paste was inserted at the junctions between the n-and p-type films. The most flexible thin-film generator fabricated in this study exhibited a P max of 10.4 nW at a temperature difference of 60 K. The current performance of the generators was too low, but we innovated a combination process to prepare them. It is expected to increase the performance by further decreasing the micro-cracks and contact resistance in the generators.

“…However, the use of the reversible thermoelectric effect (i.e., transforming thermal energy directly into electrical energy) (Seebeck Effect) had still not been explored much for the purposes of electric energy generation, as shown in [13][14][15]; in this way, the proposed device provided a valuable contribution to the implementation of this new technology.…”

“…This new technology includes the development of thermoelectric materials and applied systems, for instance, the wall of conventional furnaces, cooling of heat pipes, devices based on structured deposed, turbo compounding, Rankine and Brayton electric utilities, thermochemical recuperation, in-cylinder waste heat recovery, and improvement of cogeneration systems; which are all used for energy harvest using solid state thermoelectric devices [4][5][6][7][8][9][10][11][12][13][14][15]. The use of thermoelectric generation brings certain advantages, such as high durability, high precision, and reduced size, besides being an excellent way of collecting residual thermal energy, which means it is a clean energy cogeneration [16][17][18][19][20].…”

Characterization of a Thermoelectric Generator (TEG) System for Waste Heat Recovery

This paper presents the development and characterization of a thermoelectric generator (TEG) system for waste heat recovery to low temperature in industrial processes. The relevance of this mode of electric energy harvest is that it is clean energy and it depends only on the capture of losses. These residual energies from industrial processes are, in principle, released into the environment without being exploited. With the proposed device, the waste energy will not be released into the environment and will be used for electrical generation, which is useful for heat production. The characterization of TEGs that are used a data-acquisition system have measured data for the voltage, current, and temperature, in real-time, for temperatures down to 200 • C without signal degradation. As a result, the measured data has revealed an open circuit voltage of V OC = 0.4306 × ∆T, internal resistance of R 0 = 9.41 Ω, with tolerance ∆R int = ±0.77 Ω, where R int = 9.41 ± 0.77 Ω. The measurements were made on the condition that the maximum output was obtained at a temperature gradient of ∆T = 80 • C, resulting in a maximum power gain of P out ≈ 29 W.

“…Devices with direct contact to the human body can harvest the energy radiated from the human body by means of thermo generators (TEGs) [12]. To address the needs of telecommunications and other embedded applications, design of micro structured thermoelectric devices has been proposed in [13]. There are also commercially available sensor nodes developed by Microstrain [14] which rely on ambient energy harvesting for power.…”

The main research objective in wireless sensor networks (WSN) domain is to develop algorithms and protocols to ensure minimal energy consumption with maximum network lifetime. In this paper, we propose a novel design for energy harvesting sensor node and cross-layered MAC protocol using three adjacent layers (Physical, MAC and Network) to economize energy for WSN. The basic idea behind our protocol is to re-energize the neighboring nodes using the radio frequency (RF) energy transmitted by the active nodes. This can be achieved by designing new energy harvesting sensor node and redesigning the MAC protocol. The results show that the proposed cross layer CL_EHSN improves the life time of the WSN by 40%.
