Intelligent Crutch

2.1 Project Introduction

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.

Figure 2.1.1: modern medical crutch

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.
