We investigate the loop of Materials, Energy Harvesting, Energy Storage, and Smart Electronics to develop next-generation battery-free autonomous technologies.
Our Research Philosophy
SRE² Lab develops sustainable and self-powered technologies that reduce battery dependency and environmental impact. We harness ambient and wasted energy using triboelectric, piezoelectric, thermoelectric, and waste-derived technologies, and store it in advanced supercapacitors and microsupercapacitors, and micro-batteries. We integrate these technologies into self-powered sensors, electronic skin, flexible biosensors, and intelligent sensing systems. Our research combines energy harvesting, storage, sensing, sustainable materials, and AI-enabled technologies to create autonomous systems. These innovations target healthcare, wearable electronics, soft robotics, IoT, aerospace, defense, and smart cities.
