The FSR (Force Sensing Resistor) was originally patented over 30 years ago and was a pioneering product in the sector that became known as "Printed Electronics". Designers and engineers now had an alternative to traditional mechanical switching, and it came with a host of new features and benefits.
The basic principles of Resistive sensing have been applied to a wide variety of solutions since, including single point sensors, linear potentiometers, micro joysticks and early generation track-pads. Applications were and are wide ranging, from occupancy sensing in vehicle seats through to laptop computing, industrial controls and medical devices.
The widespread adoption of Capacitive touch sensing around a decade ago in smartphones, mobile computing and other applications should have consigned the FSR to legacy status. But in an ironic twist of fate driven by the demand for next generation tactile HMI (Human Machine Interface) solutions, Resistive force-touch sensing is now more relevant than ever.
Fast Forward to Today
Today, Resistive “force touch” is enabling Designers and Engineers to differentiate their products with new and intuitive tactile HMI solutions, simplifying User Interfaces (UI), improving User Experience (UX), and enhancing safety in many applications.
• FSR technology offers significant benefits over mechanical switching. These include improved durability, reduced packaging space and weight, reduced tooling costs & enhanced styling themes, to name just a few.
• Force Sensing overcomes the undesirable characteristics of Capacitive Sensing. That means no unintended activations, low power consumption, immunity to EMI & water events, and use with gloved hands.
• Tangio has invested heavily to improve the performance of the basic FSR technology, addressing the variability and environmental problems suffered by previous generations of the technology. And by creating new structures (like our matrix sensors) resistive sensing can deliver next-generation HMI possibilities like 3D multi-touch resistive.
• Integration, customisation & and rapid time to market. Tangio's multi-decade experience in Printed Electronics enables customers to realise their force sensing requirements quickly and affordably.
