I am always impressed when existing technology is applied to a problem in a new and unique way. That is what Hövding, a Swedish design house has done with motion sensors and microcontrollers from STMicroelectronics.
In spite of the fact that bicycle helmets reduce injuries by at least 60%, many cyclists do not use them. Existing designs are viewed as too bulky, impractical to carry around or basically just unattractive. Taking the vehicle airbag approach to the helmet, Hövding’s design is a collar worn around the neck with an airbag folded inside. Similar to the vehicle’s airbag, when an accident is detected by the motion sensor – essentially abnormal movements of the cyclist – the sensor sends a signal to the airbag. Inflating in a tenth of a second, the airbag forms a hood that surrounds and protects nearly all of the cyclist’s head and neck, without obscuring the field of vision.
