Commercial flex sensors
The Spectra flex sensors are badly designed. At the point where the metal connector pierces through printed conductor on the plastic base substrate the otherwise double laminated sensors is only single layerd, causing the materials to flex considerably. The leverage from the metal connector makes it bend all to easily here and the printed conductor cracks. No more contact. Sensor broken.
The Flexpoint bend sensors on the other hand are uniformly either single layer or double laminated and so there is not as sharp of a curve when it bends at any single point. They hold up extremely well, and maybe also the printed conductor is of a more flexible consistency.
Long (4.5 inches) and short (2.2 inches).
