As preparations continue for Expo 2025 in Osaka, Japan, workers are coping with the heat using a remarkable innovation: solar-powered cooling vests.
The ultra-thin and flexible solar panels on the vests weigh only 4 grams and are integrated with wearable technology to power fans placed around the neck area.
The vests were produced through a collaboration between Toyoda Gosei, a Toyota Group company, the solar panel initiative Enecoat Technologies, and textile manufacturer Seiren.
