Fully documented reference designs showcasing complete tile-based systems.

Piezo Haptic Ring

Wireless wearable · Haptics · BLE 5.4

A full-featured wireless smart ring delivering high-fidelity, wide-bandwidth piezoelectric haptics to the fingertip. By tightly coupling miniature TDK piezoelectric actuators with ultra-compact tile-based drive electronics, the ring enables experiences ranging from enhanced bare-finger touchscreen interactions and dynamic haptic textures on natural surfaces to discrete, contextually-aware notifications. A high-speed 9-DOF inertial sensor provides real-time motion and orientation data, while BLE 5.4 handles wireless control and data streaming.

Included tiles

Applications

  • Everyday wearables with haptic feedback
  • xR (AR/VR/MR) interaction and control
  • Vehicle and cockpit interfaces
  • Enhanced touchscreen interactions
  • Augmenting natural surfaces with dynamic textures
  • Discrete, contextually-aware notifications

Wireless Haptic Stylus

Android-compatible stylus · Haptics · BLE

An Android-compatible stylus providing real-time naturalistic haptic feedback. The stylus adds rich haptic effects to tablet, phone, and PC interfaces, augments natural surfaces with haptic cues, and delivers rich yet discrete notifications. A built-in 9-DOF inertial sensor provides motion and orientation data, while BLE handles wireless connectivity and a real-time haptic rendering engine drives high-bandwidth haptic output.
