QORVO X SIGMA CONNECTIVITY

High-Precision Force-Sensing Keypad

Our collaboration with Qorvo features an innovative human-machine interface (HMI) leveraging MEMS force sensors for multi-zone pressure detection. Unlike traditional capacitive or mechanical keypads, this solution is compatible with the use of any surface material, allowing a  smooth design, offering the additional UI dimension of “intent.”

Technical Specifications

•12-zone force-sensitive keypad utilizing MEMS force sensors

•Force triangulation algorithm for accurate pressure detection

•Adaptive digital filtering and noise reduction to ensure signal integrity

•Embedded AI calibration for drift compensation (temperature, humidity, and DC drift)

•Integrated haptic and visual feedback system

•Robust construction with metal and plastic variants for different applications

•Sub-microstrain sensitivity, allowing detection of smallest displacements

•Optimized for embedded systems, enabling real-time processing with minimal power draw

Use Cases

This force sensor-based keypad aims to propose a disruptive concept to access control systems, rugged industrial input panels, and other smart user interfaces, where seamless interaction and safety play an important role.
