Sonic Pixel for Smart Glasses

Add haptics, audio and sensing to Smart Glasses with a single microchip.

Acciosonic puts one AlScN pMUT phased-array chip at the temple. It delivers subtle haptic feedback, directed private audio and near-field physiological sensing from one CMOS-compatible component.

One Sonic Pixel at the temple enables three distinct modalities.

Challenge

Current Smart Glasses are still missing three human interfaces.

Visual and audio feedback are already overused. Next-generation frames need interaction that is subtle, private and always available without adding separate motors, speakers, sensors or another wearable.

H

Haptic interaction

Frames lack a discreet feedback channel for confirmation, navigation and silent notifications.

A

Private audio

Open-ear speaker integration remains constrained, and privacy cannot be ensured in public spaces.

S

Physiological sensing

Basic physiological signals are absent from the frame, forcing users to rely on separate wearables.

Solution

A single Sonic Pixel at the temple provides haptics, audio and sensing.

The same pMUT array switches between three operating modes: it generates focused ultrasonic pressure, receives near-field pulse-echo signals and steers a private audio carrier toward the ear.

F

Feel

Silent haptic feedback delivered at the temple, such as subtle confirmations and directional cues.

S

Speak

Directed private audio for prompts or messages without earbuds and without leakage to bystanders.

D

Detect

Near-field physiological sensing for pulse, heart rate and SpO₂ through temple skin contact.

In the frame

One chip, placed where Smart Glasses already touch the skin.

Sonic Pixel sits in the frame at the temple. From that single location, the array can create tactile cues, sense near-field physiological signals and steer audio toward the ear canal.
