“…When heat flows from the hot surface to the cold surface through the thermoelectric material, the free charges (electrons and holes) of the semiconductors are also moving. This movement of load converts thermal energy into electrical energy (Prabhakar et al, 2018).…”

This study investigates the current situation of electricity generation from non-conventional renewable energy sources (NCRES) in Colombia. In general, it was shown that Colombia has potential in renewable sources such as solar, wind, and biomass. However, barriers such as lack of human capital, policies focused on conventional technologies and high investment costs have impeded their growth. Although the development of these sources has been encouraged through Law 1715 of 2014, more policies and developments are needed to promote this type of NCRES. The use of thermoelectric devices (TED) can become a potential NCRES alternative, while the political and technological conditions improve in Colombia. Around the world, TEDs have allowed the recovery of waste heat in a variety of industrial applications and the automotive sector. They are allowing in the latter, not only the generation of electric power, but also the reduction in engine emissions. Besides, its characteristics have allowed it to be used for the generation of electric power, both in developed and developing countries. In this document, an example presentation is developed that demonstrates the applications of the TED in the cases above to demonstrate the potential that the TED can have in almost any place that has a heat source.

“…State-of-the-art thermoelectric (TE) materials such as bismuth telluride alloys are rigid, inorganic materials based on expensive and toxic elements and require high-energy complex manufacturing. Recently, development of low-cost, flexible TE materials has drawn significant attention for potential emerging applications in wearables, sensors, and Internet of Things. , Recent efforts have been focused on conjugated polymers such as poly(3,4-ethylenedioxythiophene) (PEDOT) and poly(3-hexylthiophene-2,5-diyl) (P3HT) due to their easy manufacturability, low toxicity, and high flexibility, giving them an edge over the conventional inorganic counterparts. − These conducting polymers can provide high electrical conductivity by heavy doping and inherently low thermal conductivity, both of which are desired for high TE performance as presented in the dimensionless thermoelectric figure of merit, zT = S 2 σT /κ, where S is the Seebeck coefficient, σ is the electrical conductivity, κ is the thermal conductivity, and T is the absolute temperature. The numerator ( S 2 σ) in zT is called the power factor, as it determines the power output for a given temperature difference.…”

As an emerging flexible thermoelectric material, polymer composites with embedded carbon nanotube (CNT) networks have shown promising properties, but their thermoelectric transport has not been fully understood. Herein, we embedded CNT networks in poly(dimethylsiloxane) (PDMS) elastomers and analyzed their thermoelectric properties using Landauer theory. We find that the simultaneous increase in Seebeck coefficient and electrical conductivity with increasing CNT content up to ∼40% can be attributed to the tunneling transport at CNT junctions with the gap distance decreasing with increasing CNT content. Beyond 40% CNTs, both properties are reduced and saturated due to the reduced PDMS content and increased material nonuniformity, which effectively replaced the PDMS gap with an air gap at the junction with a higher barrier to reduce the properties. Our results and analysis provide important insights into the material optimization of hybrid thermoelectric composites based on CNT networks and many other nanoscale fillers.

In recent advancements within sensing technology, driven by the Internet of Things (IoT), significant impacts are observed on health sector applications, notably through wearable electronics like electronic tattoos (e‐tattoos). These e‐tattoos, designed for direct contact with the skin, facilitate precise monitoring of vital physiological parameters, including body heat, a critical indicator for conditions such as inflammation and infection. Monitoring these indicators can be crucial for early detection of chronic conditions, steering toward proactive healthcare management. This study delves into a thermoelectric sensor e‐tattoo designed for detailed skin temperature mapping. Utilizing a novel design, this sensor detects temperature variations across thermoelectric stripes, leveraging screen‐printed films of p‐type Bi0.35Sb1.65Te3, n‐type Bi2Te2.8Se0.2, and poly(vinyl alcohol) (PVA) for enhanced thermoelectric and flexible properties. The application of a prototype printed thermoelectric device on temporary tattoo paper, a pioneering development in wearable health technology is demonstrated. This device, validated through numerical simulations, exhibits significant potential as a non‐invasive tool for temperature monitoring, highlighting its value in health diagnostics and management.
