Spine posture reminder
I've recently started a project for my electronics class:
My idea is to use angle sensors positioned on the spine to track it's position in 3D.
If the user slouches or goes into a non-optimal posture for a certain time (maybe 1min to avoid accidental triggering), the system recognizes this and reminds the user via an eletrostimulation-induced tingling sensation.
Here's a shitty paint drawing of my idea:
For now, I'm thinking of using simple potentiometers with a solid linked chain. Adhesion will be provided by one of my labmate's silicon adhesive (resists sweat, good strength and doesn't leave residue behind.)
My big problem currently is the electrostimulation system. I'm having trouble finding data on where I should start, most of what I can find is made to cause pain...
