Problem & Solution
Three functions not yet covered by a single component.
Today's Smart wearables address only sight and hearing. Haptic touch, vital sensing and private audio remain entirely unaddressed. Adding separate motors, sensors and speakers creates bulk, weight and power overhead — the miniaturisation wall of every next-generation frame. Users need subtle, private, always-on interactions — a gap no existing single component can fill.

Acciosonic closes all three gaps with one chip.
Acciosonic answer
Sonic Pixel — one layer, three senses.
A phased array of AlScN pMUT membranes on a single CMOS-compatible chip. The same array switches between three operating modes — generating touch, reading vital signs and steering audio into the ear canal.

Feel
Mid-Air Haptics
A phased-array pMUT generates focused ultrasonic pressure — creating the sensation of touch in free air, without any mechanical contact.

Near-Field Sensing
The same array switches to pulse-echo mode — measuring pulse, heart rate and SpO₂ through temple skin contact. No display, no wristband.

Directed Private Audio
A modulated > 150 kHz carrier is beam-steered into the ear canal. Non-linear demodulation creates audible sound only at the target — inaudible everywhere else.

In the frame
One chip at the temple. Three modalities out of one array.
The pMUT chip sits inside the Smart Glasses frame and rests against the temple — the most sensitive skin zone on the head. Steerable ultrasonic wavefronts emanate from a single phased array to feel, detect and speak.

Silent, private touch cues at the temple.
The pMUT chip in the Smart Glasses frame contacts the temple — the most sensitive skin zone on the head. Steerable ultrasonic focal points generate tactile pressure above the chip surface in real time. Phase delays across the array elements position and shape each haptic zone independently.
Silent alerts and navigation cues are imperceptible to bystanders but immediately clear to the wearer. No audio, no visual needed.
Use case · Smart Glasses
Private, eyes-free navigation and alerts — even in noisy environments. The wearer gets a directional cue at the temple before consciously looking; the person sitting next to them notices nothing.
D Detect · Near-Field Sensing
Health sensing through the temple — no wristband.
The identical pMUT array switches to pulse-echo receive mode. Reflected ultrasonic wavefield analysis extracts object position, motion velocity and biometric parameters. No separate sensor hardware, no companion device.
Because the chip in the frame rests against the temple skin, pulse, heart rate and SpO₂ are captured continuously — data streams silently in the background while the glasses are worn.
Use case · Health Sensing
Clinical-grade vitals from the Smart frame — no extra wearable. Pulse-echo bursts capture micro-Doppler; algorithms extract heart rate and SpO₂ in real time; data syncs to the companion app or cloud.
S Speak · Directed Private Audio
An invisible private speaker in the frame.
A modulated ultrasonic carrier beam above 150 kHz demodulates into audible sound only at the point of incidence — the wearer's ear canal. Audio stays confined to a single-user zone. No earbuds, no separate speaker hardware.
The same phased-array phase & delay control that steers haptic focal points steers the acoustic beam — one chip, two completely different physical outputs.
Use case · Smart Private Audio
Navigation prompts or call audio rendered into the ear canal — clear speech, zero leakage to the surroundings. The pMUT in the Smart frame acts as a private speaker; anyone standing next to the wearer hears nothing.
Use cases
Three modalities — one Smart Glasses frame.
The same phased-array chip drives three end-user scenarios, each individually shipping-ready and each independent of a display, earbud or wristband.

Feel · Navigation & Alerts
Silent directional cues at the temple.
- Glasses detect upcoming turn via GPS
- pMUT fires focused haptic pulse to temple
- Wearer receives silent directional cue
- No audio, no display interaction needed
D
Detect · Continuous Health
Clinical vitals in the background.
- pMUT presses gently on temple skin
- Pulse-echo burst captures micro-Doppler
- Algorithms extract HR, SpO₂ in real time
- Data syncs to companion app or cloud
S
Speak · Private Audio Overlay
A speaker no one else can hear.
- Navigation or call audio rendered
- pMUT steers > 150 kHz beam to ear canal
- Demodulation occurs at the ear only
- Clear speech, zero leakage to surroundings
