Hello to all,
for the thesis I am planning a corset "interactive" that helps the wearer to breathe with your diaphragm.
In theory the circuit part by a stretch sensor which detects the movement of the belly and sends a signal to the lilypad which in turn actuates a series of nitinol, which move the structure of the corset.
Has anyone ever programmed nitinol?
If I understand correctly from different forums, I have to program it as the switch with an LED but the movement should be obvious that I would get nice and wide:
structure pleated bodice and made by many (like many folds accordion 2D become 3D and 2D then back again)!
For now, I bought two nitinol wires 150 and 250 um and a drizzle of flexinol (similar to the nitinol) from 500 um to several tests with the fabric.
Shape memory wire is activated with heat. Generally you run a current through the wire to cause the wire to heat up. This can take substantial current so you may need both a hefty battery and transistors to switch the current.
