About

Takahiro Hirotsu is a pioneering researcher in the field of soft materials and energy conversion, with a particular focus on light-responsive and thermoelectric systems. His most notable contribution is the development of a light-triggered thermoelectric conversion device based on a carbon nanotube–polymer hybrid gel, published in 2009. This innovative work demonstrated how a hydrogel composed of lysozymes, poly(ethylene glycol), phospholipids, and functionalized single-walled carbon nanotubes could convert light energy into electrical power through a thermoelectric mechanism. By creating a photoinduced thermoelectric conversion module, Hirotsu opened new pathways for harnessing solar energy using flexible, biocompatible materials. His research bridges the gap between nanotechnology, polymer science, and energy harvesting, offering sustainable solutions for next-generation devices. With his work garnering attention in the field, Hirotsu continues to inspire advances in smart materials and green energy technologies, making him a key figure in the development of hybrid systems for efficient energy conversion.
