I thought about how strain gauges may be incorporated in the project.
In theory, they could replace the switches and the design can be changed to achieve the desired result of a voltage indicating where a bend was made.
However, practically it does not work well for the following reasons:
- Current strain gauges are as durable as a mechanical switch. No advantage gained.
- Mechanical strain gauges are expensive.
- They generally have low strain to resistance yields.
-Can break if stretched/strained too much.
There is some promise for a more flexible and more sensitive strain gauge.
I will keep searching for alternatives to a mechanical switch.
