Touch on Metal Buttons With Integrated Haptic Feedback Reference Design
Texas Instruments
This reference design uses our inductance-to-digital converter technology to provide a high-precision method to sense button presses on a metal surface and our haptic drivers provide high-quality haptics feedback to the user. TIDA-00314 demonstrates techniques for system design: environmental compensation and electromagnetic interference protection.Watch the TIDA-00314 overview video on the touch-on-metal buttons with integrated haptic feedback.
Features
- Replaces mechanical buttons with high-resolution inductive-sensing based touch-on-metal detectionCustomizable haptic feedback and waveforms provide a high quality user experienceProgrammable 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 contaminantsWorks with gloves: underwater (if sealed) and in harsh environmentsCan be used for pressure and multi-step button press sequencesThree button options omplemented:20-mm button3 mm x 10 mm (two buttons)3-mm buttonAlternative button configurations can be implemented with different mechanical designs
