Abstract:
1. A variable capacitor comprising: a printed circuit board having a predetermined dielectric coefficient; a metal pad disposed on a first side of said printed circuit board; a metal cantilever disposed on a second side of said printed circuit board that is attached to said printed circuit board at a first end of said metal cantilever, said metal cantilever having a predetermined elasticity; a deflector disposed to engage said metal cantilever so that said predetermined elasticity of said deflector is sufficient to hold said deflector in a neutral position when a deflection force is not applied to said deflector, and disposed to deflect said metal cantilever when a force is applied to said deflector which causes said metal cantilever to deflect away from said printed circuit board in a curvature that produces a progressive, measurable charge in capacitance over a full range of deflection of said deflector.
