UK UNIVERSITY RESEARCHERS DEVELOP SMART HELMETS FOR SOLDIERS
A team of researchers at Nottingham Trent University in the UK are developing smart helmets to help prevent soldiers from incurring hearing injuries. Tiny microphones are being knitted into the fabric covering army helmets to record the noise soldiers experience in the field. The ATRG’s e-yarn technology platform will be used to embed the micro electromechanicalsystem microphones (MEMS), keeping them dry. The microphones knitted into the fabric will be undetectable to the user and avoid interfering with military activities. The MEMS are capable of measuring the level of noise that soldiers are exposed to in the field over a length of time.
The MEMS will be positioned above each ear as an acoustic injury is more likely to be asymmetric due to military activities, meaning one ear might be affected more than the other. According to the researchers, a short exposure to sound levels exceeding 140dB can cause permanent hearing damage.
