Shown on this slide are some guidelines for proper FSR usage. The first of these is to follow the seven steps of FSR optimization discussed on the previous slides. If possible, use a firm, flat and smooth mounting surface. Be careful if applying FSR devices to curved surfaces. Pre-loading of the device can occur as the two opposed layers are forced into contact by the bending tension. The device will still function, but the dynamic range may be reduced and resistance drift could occur. The degree of curvature over which an FSR can be bent is a function of the size of the active area. The smaller the active area, the less effect a given curvature will have on the FSR’s response. Avoid air bubbles and contamination when laminating the FSR to any surface. Use only thin, uniform adhesives, such as Scotch™ brand double-sided laminating adhesives. Cover the entire surface of the sensor. Also, be careful of kinks or dents in active areas. They can cause false triggering of the sensors. Protect the device from sharp objects. Use an overlay, such as a polycarbonate film or an elastomer, to prevent gouging of the FSR device. Lastly, use soft rubber or a spring as part of the actuator in designs requiring some travel.
