The history of non-mechanical HMI sensing dates back more than 30 years. Early “resistive” solutions such as FSRs and ITO touchscreens were force based but shared similar problems such as poor sensitivity and environmental performance.
The advent of the smartphone drove the adoption of capacitive touch sensing, but despite it’s proliferation, particularly in mobile devices, it introduced even more problems. High power consumption, no pressure sensing, and the inability to be used by a gloved hand to name just a few.
Imagine a technology that combined the best features of what went before without the drawbacks. Enter QTC sensors from Peratech – the next generation in HMI touch.
