20/20 Vision

20/20 Vision · Team 20 · Sleep-safe closed loop

Deep sleep
without scratching.

Every 10th person lives with atopic dermatitis. In a flare the hands scratch through the night — you wake up with damaged skin and no deep rest. 20/20 Vision detects the scratching and gently interrupts it before it does more harm, while you stay asleep.

The cue is a haptic pulse — short enough to stop the hand, not a wake-up alarm.

One night, in four pictures

You scratch at night.
You don’t feel it. You don’t remember.

Atopic dermatitis disrupts far more than skin — it disrupts sleep. Scratching damages the skin, the itch gets worse, deep sleep is gone: a cycle of itch, scratch and sleep loss you cannot control. Here is what one night looks like with the band on.

A person asleep in bed wearing the band on the wrist 23:40

You fall asleep

The band sits on the wrist and just listens. No screen, no light.

Still asleep, the hand scratches the forearm and the skin turns red 03:14

The hand starts to scratch

You are still asleep. The skin is already getting damaged — and you have no idea.

The band gives a short, gentle vibration and the hand relaxes 03:14 · +2 s

A short pulse

The band recognises the scratch rhythm and gives one soft buzz. The hand stops. You do not wake up.

In the morning the person reads the night receipt on a phone 07:30

03 · Inventive step

Others measure the night. We close the loop.

Existing approaches measure scratching, protect the skin passively, or treat the itch with drugs. None of them stops the hand at 03:14. Our system closes the loop: sense → detect → interrupt → prove.

What already exists

Trackers count night scratch and stop there. Gloves and wraps hide the hands. Creams and pills treat the inflammation and still leave the night unmeasured. Measurement alone does not close skin.

Secret sauce

A wrist device reads the rhythmic signature of scratching from motion — EMG under evaluation — and delivers a short haptic vibration the moment a bout starts. The difference is not the measurement. It is an adaptive, sleep-safe intervention plus a morning record that you or your clinician can review.

04 · How it looks and works

One sealed loop. Four steps. A night you can show.

You wear the band to sleep. It recognises the motion signature of scratching, gives a short vibration that interrupts the hand without waking you, and in the morning shows you what happened.

01

Sense

You wear the wrist device during sleep. The prototype combines an accelerometer/IMU, with surface EMG under evaluation.

02

Detect

The algorithm identifies the motion signature of scratching and separates it from ordinary sleep movement.

03

Interrupt

On detection the device gives a short vibration — enough to interrupt the motion, not enough to wake you.

04

Prove

In the morning the app shows scratching events, interventions and summary statistics — for you and your clinician.

05 · Next step

Request a 7-night home pilot.

You give us one wrist and one typical week. We instrument the nights and return scratch receipts against what you remember in the morning. No clinic integration. Creams stay as they are. The next step is one night, not a procurement cycle.

Request captured on this device. Copy the summary or send it on — we read every 7-night ask.

06 · Why this is believable

The mechanism already moved a number.

An AI-enabled wearable with a haptic cue has already reduced nocturnal scratching in a published trial. We make that loop reachable — a band you can put on tonight, not a prescription.

JAMA Dermatology, 2025

Yang et al. closed a wearable loop with a haptic cue in mild atopic dermatitis. Mean total scratch per night −28%. Mean scratch duration −40%. Events per hour of sleep opportunity −39%. Duration per hour −50%. Success rule: less scratch, sleep not worse.
