Feel the difference: Azoteq’s haptic and sensing ICs at Astute’s Stand

Replace mechanical buttons with solid surfaces that still feel like buttons—waterproof, wear-free, and precisely tuneable.

Astute is showcasing Azoteq’s IQS39x haptic ICs and ProxFusion sensing technology at Hardware Pioneers Max 2026. If you’re designing touch interfaces that need to feel responsive without moving parts, this is the silicon to see – and touch! Book a slot to chat with their experts here.

The problem with flat interfaces

Inductive and capacitive buttons look sleek, but users miss the tactile confirmation of a physical press. Without feedback, they hesitate, press harder, or trigger inputs accidentally. For wearables, medical devices, and industrial controls, that’s not just frustrating—it’s a reliability issue.

Azoteq says it solves this by combining capacitive sensing and haptic feedback on a single chip, driving Linear Resonant Actuator (LRA) motors to deliver precise vibration exactly when a touch registers.

What makes the IQS39x family different

• Integrated H-bridge driver powers LRA motors directly—no external driver circuitry needed.
• Closed-loop auto-resonance tracking maintains consistent vibration strength as motors age, temperatures shift, or mounting conditions vary.
• Multiple sensing modes in one IC: capacitive and inductive via Azoteq’s ProxFusion architecture.
• Ultra-low power operation with wake-on-touch, suited for battery-powered wearables and IoT devices.
• Packages as small as 2mm × 2mm, fitting into space-constrained designs.
• The IQS39x devices can be paired with other sensing technologies (for example, Hall-based encoders such as the IQS326) to enable combined solutions, rather than integrating these functions directly.

The IQS391/392 are haptic driver devices only, while the IQS396/397 combine haptic drivers with a single capacitive or inductive sensing channel.

Practical applications

• Sealed interfaces for industrial equipment, appliances, or medical devices—no ingress points, no mechanical wear.
• Hidden-until-lit controls on glass or metal surfaces that respond with defined tactile clicks.
• Rotary encoders and scroll wheels (IQS326).
• Wearables requiring gesture detection, proximity wake-up, and precise touch discrimination through gloves or overlays.

Why visit Astute’s stand

Azoteq representatives will be at the stand to

• Handle working demos of haptic feedback on sealed surfaces.
• Discuss your interface challenges—overlay materials, power budgets, environmental conditions.
• Get evaluation kits and design guidance to accelerate your development.
