3D printed Thermoelectric generators (TEGs) for battery-free industrial IoT (IIoT) sensors
H2O-SCTM 0623 and H2O-SCTM 0723 → p- & n-type highly conductive carbon aqueous ink products with “on-purpose” induced stable p- or n-type carrier concentration character for power generation device architectures and fully printed high-power density thermoelectric generators.
PDOTEGTM → Battery-Free IIoT Network Nodes Powered by Thermal Energy Harvesting.
The PDOTEGTM is a 3D printed sustainable Thermoelectric generator (TEG) designed for battery-less power supply of IIoT sensors from existing temperature gradients (or standard hot surfaces).
IIOT-driven predictive maintenance isn’t the future – it’s the new standard!
Traditionally, hashtag #IoT sensors require frequent hashtag #battery replacements, leading to high costs (e.g. 98% of businesses report productivity loss from Downtimes – even a single hour of interruption can cost over 100K € in lost output) and significant environmental impact.
But PDOTEGTM changes the game!
PDOTEGTM aligned with EU green goals, CO₂ reduction & renewable energy advancements relies on:
Scientific Impact → 3D printed TEGs push boundaries of Power Conversion Efficiency (PCE), novel organic-based TEGs ~2–6% (conventional inorganic-based TEGs ~5–8%).
Industrial Impact → Self-powered diagnostic units for condition monitoring of machinery & installations
Powered by existing temperature gradients:
Thanks to our technology, PDOTEGTM operates without batteries, harvesting energy from ambient heat losses eliminating maintenance costs and issues related to battery management.
PDOTEGTM innovation marks a decisive step toward a more sustainable and autonomous IoT, ready to transform the way we interact with connected industrial environments.
