Fraunhofer researchers have developed a helmet with an integrated acceleration sensor for drivers of construction vehicles. The helmet sensor measures harmful vibrations that affect the body. A software analyzes the sensor signals and shows the stress on the affected person. This allows corresponding relief measures to be taken. A flexible piezo-electret film serves as the sensor. A demonstration model for the Flexeras project will be presented at the joint Fraunhofer booth at the Hannover Messe (April 22–26, 2024, Hall 2, Booth B24).
