# Bengaluru team’s thin film boosts heat sensor sensitivity 100 times 2026-08-13T03:16:17+00:00 | Technology | Indian Opinion Desk Corroboration: 1 independent outlet Researchers at Bengaluru's Jawaharlal Nehru Centre for Advanced Scientific Research have created a scandium nitride thin film that produces over 124 millivolts of voltage per degree Kelvin of temperature difference near room temperature. That is nearly 100 times larger than the response predicted by conventional theory for ordinary solid materials, the team reports in Science. The material works by concentrating electrical charges in tiny conducting regions separated by barriers, amplifying the Seebeck effect. A 7.5-nanometre-thick film gave -83.41 millivolts per Kelvin near room temperature. Applications could include highly sensitive thermal imagers, heat-flow sensors, and waste-heat harvesters. An Indian patent application has been filed covering the materials and sensors. ## Coverage - timesofindia.indiatimes.com Tags: Bengaluru research, JNCASR, scandium nitride, Seebeck effect, sensor technology, thin film Canonical: https://indianopinion.org/bengaluru-teams-thin-film-boosts-heat-sensor-sensitivity-100-times/ License: Summary and commentary (c) Indian Opinion, reusable with attribution.
