| Force Sensitive Resistor | |
| Basic Features | Pressure sensitivity (increased pressure decreases resistance). 2 polyester layers printed with resistive ink. Typically manufactured with multiple individual touch locations rather than as a single large switch. |
| Application example | Seat sensor for airbag that measures occupant weight to adjust force required for airbag deployment. |
| Single or Multi-touch |
Multi-touch |
| Measures movement of touch | No |
| Tactile response possible? | No |
| Relegendable | Yes |
| Largest available part size (note: size may be affected by part shape) | 30” square |
| Switch Density | 3/8” center-to-center |
| Actuation force measured | |
| Lifetime actuations (lab conditions) | Up to 50 million |
| Custom/odd shapes possible? (Polygon, 3-D, etc.) | Yes |
| Backlighting options | No |
| Sunlight readable | Yes |
| Emboss/texture options | Yes |
| Development time | 4 Weeks |
| EMI/ESD resistance | Average |
| Chemical resistance | Dependent on polyester coating |
Force Sensitive Resistors
Does your application require the detection of pressure applied across multiple surface locations, simultaneously? Our Force Sensitive Resistors may be the switch alternative you need.
Force Sensitive Resistors are a, time and weight estimations not obtainable from standard input options such as membrane switches or touch screens.
Our Force Sensitive Resistor technology allows the creation of custom sizes and shapes (i.e. can be formed around a joystick to detect squeezing). If your application requires determining input involving pressure/weight, duration and surface area of a touch, for example, within the medical or automotive markets, Force Sensitive Resistors are a viable option for you.
