For many hundreds of years, crutches have always looked the same. They were essentially a stick with a grip on top. The biggest update they have received is a forearm support. Looking at todays development in microcontroller technology, small bluetooth connectivity and smartphones, this regular mobility aid seems antiquated.

With many everyday devices becoming "smart" and connected products, one may wonder if there is any application in a "smart" crutch. With sensors like a scale, force measurement and acceleration, exact analysis of the walk can be possible. Bluetooth connectivity allows the synchronisation and analysis on a smartphone. Highly energy efficient microcontrollers combined with deep-sleep modes can allow long runtimes, while the small package of modern microelectronics and high density batteries are enabling a highly integrated design.
