TouchPoint chips power SmartSurface touch interfaces with accuracy and control
UltraSense TouchPoint HMI Controllers fully integrate multi-mode touch sensing, lighting control, and algorithm processing in a single chip
UltraSense Systems is launching UltraSense TouchPoint Q, the world’s first piezoelectric strain sensor designed to bring a better touch experience to automotive interfaces.
The specifications are:
- Brings instant robustness to capacitive touch systems with calibratable force thresholds
- Immune to temperature sensitivity, mechanical and aging stresses, and signal drift from adhesive thermal expansion mismatch (compared to other force-sensing technologies)
- Unique MEMS-based QuadForce architecture embeds 4-strain sensors into every component, enabling differential sensing and pattern recognition when using machine learning
- Fully qualified to AEC Q100 Grade 2 (-40 to +105C)
Traditional capacitive touch systems have suffered from oversensitivity, causing frustrating false triggers, or from lack of sensitivity, creating a poor user experience. When earlier force-sensing technologies were added to capacitive touch systems (i.e. optical, parallel plate capacitance, or piezoresistive), results were sub-par: a non-premium feel, required visual movement of the surface, and/or expensive calibration steps across the manufacturing process. As a result, some auto makers released first-generation solid-surface capacitive touch systems to less-enthusiastic reviews.
“TouchPoint Q enables automotive tier-suppliers to deliver a new generation of more capable touch sensing functions,” said Daniel Goehl, UltraSense Systems Chief Business Officer. “TouchPoint Q can easily and cost-effectively augment already designed capacitive systems with a better force-sensing solution to improve the user experience and manufacturing scalability.”
