Advanced Sensor and Energy Harvesting Materials

Wearable biomedical devices increasingly rely on materials that can simultaneously sense the body's signals and generate the electricity needed to operate — eliminating the need for bulky batteries by harvesting energy from motion, pressure, or heat. Flexible and stretchable sensors, often built from nanoscale components and engineered polymers, can conform to skin and tissue while detecting physiological data such as pulse, strain, and biochemical markers in real time. Triboelectric nanogenerators, which convert mechanical contact between dissimilar materials into usable electrical charge, have emerged as a particularly promising route to fully self-powered electronic skin systems. Active research is now focused on improving the durability and output consistency of these materials under the irregular, repetitive deformation of everyday movement, and on integrating multiple sensing and harvesting functions into a single seamless device without compromising comfort or biocompatibility.
