Description

This TI Design uses Texas Instruments' inductance-to-digital converter technology to provide a high-precision method to sense button presses on a metal surface and TI's Haptic Drivers provide high quality haptics feedback to the user. TIDA-00314 demonstrates techniques for system design, environmental compensation, and electromagnetic interference protection.

Watch a TIDA-00314 Overview video on the Touch on Metal Buttons With Integrated Haptic Feedback NOW.

Features
  • Replaces Mechanical Buttons With High-Resolution Inductive-Sensing Based Touch On Metal Detection
  • Customizable Haptic Feedback and Waveforms Provide High Quality User Experience
  • Programmable Force Touch Button Sensitivity (from Light Touch to Hard Press)
  • One Continuous Sheet of Metal Sealed and Grounded Against Electromagnetic Interference (EMI), Water, Oil, Dirt, and Other Contaminants
  • Works With Gloves, Underwater (if Sealed), and in Harsh Environments
  • Can Be Used for Pressure and Multi-Step Button Press Sequences
  • Three Button Options Implemented:
    20-mm Button
    3 x 10 mm (Two Buttons)
    3-mm Button
  • Alternative Button Configurations Can Be Implemented With Different Mechanical Designs
