TEPOWER Completes First Prototype and Seeks Industrial Partners for Real-World Testing

We are pleased to announce that the TEPOWER project has successfully completed its first functional prototype of a flexible thermoelectric generator designed to power microelectronics using human body heat.

The prototype demonstrates the feasibility of battery-free operation for ultra-low-power devices by harvesting energy from the natural temperature difference between the human body and the surrounding environment. This milestone marks an important step toward self-powered wearable electronics.

Following this achievement, TEPOWER is now seeking industrial partners to collaborate on real-world testing and validation. In particular, we are looking for partners working with photoplethysmography (PPG) sensors or related wearable health technologies to integrate and test the TEPOWER generator with commercial PPG devices.

Partner collaboration will focus on:

• integration of the TEPOWER generator with existing PPG hardware,

• testing under realistic use conditions,

• evaluation of performance, reliability, and user comfort,

TEPOWER Advances Battery-Free Power for Wearable Sensors

The TEPOWER project is developing a new generation of flexible thermoelectric generators designed to power microelectronics and sensors using human body heat, eliminating the need for batteries and external charging.

Led by researchers at the University of Latvia, TEPOWER focuses on creating patch-like, flexible power modules capable of supplying energy to ultra-low-power devices such as photoplethysmography (PPG) sensors used in health and wellness monitoring. These sensors are commonly found in smartwatches, fitness trackers, and medical patches, where battery lifetime and maintenance remain major limitations.

The project’s goal is to fabricate a Technology Readiness Level (TRL) 5 demonstrator that converts the temperature difference between the human body and surrounding air into usable electrical energy. By doing so, TEPOWER aims to enable continuous, self-powered operation of wearable and sensing devices—without battery replacement or recharging.

A key motivation behind the project is the growing environmental and economic cost of batteries. Small electronic devices often require frequent battery replacement, with annual costs reaching 90–350 USD per device. At the same time, waste batteries from small electronics have some of the lowest recycling rates, with only about 46% of portable batteries collected for recycling in the EU. TEPOWER addresses this challenge by offering a sustainable, battery-free alternative.

The interdisciplinary project team brings together expertise in advanced materials, electronics, and business development, combining scientific research with real-world application potential. Alongside technology development, the project also focuses on know-how protection, prototype validation, and preparation for further technology scale-up.

The main expected outcomes of TEPOWER include:

• advancing the technology from TRL 4 to TRL 5,

• developing a functional patch-like thermoelectric generator prototype,

• demonstrating battery-free powering of a PPG or environmental sensor,

• laying the groundwork for future commercialization and partnerships.

By harvesting energy directly from the human body, TEPOWER contributes to the vision of self-powered electronics that are more sustainable, user-friendly, and always on.

Latvian Scientists Turn Body Heat into Electricity Using Nanocomposites

Popularzinatniskais_raksts_Ilustreta_Zinatne-1.pdf

Researchers in Latvia have developed innovative nanocomposite materials capable of converting human body heat into electrical energy, opening new possibilities for self-powered microelectronics and sensors.

The technology is based on flexible thermoelectric materials that generate electricity from the natural temperature difference between the human body and the surrounding environment. Unlike traditional rigid thermoelectric materials, these nanocomposites remain lightweight, flexible, and suitable for wearable applications.

The core of the innovation lies in combining carbon nanotube networks with bismuth- and antimony-based thermoelectric nanostructures, encapsulated in biocompatible polymers. This architecture allows efficient heat-to-electricity conversion while maintaining mechanical durability and comfort for skin contact.

According to the researchers, the human body continuously releases thermal energy—up to around 100 watts—most of which is normally lost to the environment. By harvesting even a small fraction of this energy, the developed technology can power low-energy devices such as wearable health sensors, environmental monitoring systems, and autonomous IoT devices, without the need for batteries.

One of the key advantages of the technology is its ability to operate in darkness, indoors, and in cold environments, where solar energy is unavailable. This makes thermoelectric energy harvesting especially attractive for medical wearables and long-term monitoring applications.

The research team is currently testing prototype flexible thermoelectric generators, including patch-like devices designed to be worn on the body. These prototypes demonstrate stable performance under real-life conditions, including bending and continuous wear.

The development represents an important step toward a battery-free future, reducing electronic waste and dependence on critical raw materials used in conventional batteries.

TEPOWER builds on this scientific foundation to bring the technology closer to real-world applications in wearable electronics and self-powered sensor systems.
