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).
Not really a fan of this. The spine will attenuate much of the vibration, particularly in lower frequency bands. Higher frequency bands will be attenuated by the space between the helmet and the head. This sensor will then underestimate what the person is experiencing. I guess it’s a benefit for employers who could then claim they are staying under the limits, while they are actually over the limits.
It’s much easier to just slap a sensor right on the seat, and more accurate, too.
I can’t find a research paper or something on this particular sensor, though.
