A team of Indian researchers has developed a nanotechnology-based crash sensor that could activate airbags in automobiles, faster than conventional technology. The crash sensors developed by the team at the Indian Institute of Science, IISc, Bengaluru based on nanomaterials has the faster response time to open airbags leading to passenger safety in case of an accident. It is light in weight and occupies less space.
Currently, automobile manufacturers use a variety of crash sensors such as gas dampened ball type, G-switch type or Reed switch, which are based on the relative motion of mechanical components like spring, ring-magnet and switches.
