Earlier signals. Calmer support.

Know when stress is rising. Respond before it escalates.

PaShield is a screenless wearable system designed to help parents and caregivers recognize rising stress in neurodivergent children and respond earlier.

Child's signals change

PaShield recognizes a personalized pattern

Caregiver receives a discreet alert

Caregiver responds earlier

Early distress can be difficult to see.

A child's stress can begin rising before the outward signs become obvious. By the time a caregiver notices the change, the child may already be overwhelmed.

01

Stress can begin before visible behavior changes.

02

Some children cannot easily communicate that they are becoming overwhelmed.

03

Once distress escalates, caregivers may have fewer calm options available.

How PaShield works

From subtle signals to timely support.

  1. 01

    Detect

    The child's screenless wearable monitors changes in relevant physiological and movement signals.

  2. 02

    Personalize

    PaShield learns patterns relative to the child's individual baseline.

  3. 03

    Alert

    When multiple signals meaningfully change, the caregiver receives a discreet alert.

  4. 04

    Respond

    The caregiver uses the strategy appropriate for that child and situation.

Prototype target
Up to 3 minutes earlier warning

Timing varies by child and situation. Prototype performance is currently being evaluated — this is a development target, not a validated guarantee.

The system

One system. Three simple components.

For the child

PaShield Sensor Wearable

A comfortable, screenless wearable designed to passively capture relevant physiological and movement signals.

  • Screenless
  • Passive sensing
  • Personalized baseline
  • Designed for everyday use

For the caregiver

PaShield Alert Band

A simple wearable that provides a discreet vibration without requiring constant phone checking.

  • Quiet vibration
  • Immediate awareness
  • Simple alert levels
  • Fast acknowledgment

For deeper context

PaShield Caregiver App

A lightweight companion app for alert context, pattern history, caregiver handoff, and optional response logging.

  • Plain-language context
  • Pattern history
  • One-tap logging
  • Caregiver coordination

Why timing matters

A small head start can change the response.

Earlier awareness gives the caregiver more opportunity to use the support strategy appropriate for that child.

PaShield does not tell every family to respond in the same way. It helps the caregiver notice earlier and use the strategy that works for that child.

Reduce noise, light, or stimulation

Pause or simplify a transition

Move to a familiar or quieter space

Offer the child's preferred regulation support

Alert another trusted caregiver

Why PaShield

Designed around the caregiver's reality.

Passive for the child

No screen interaction, symptom diary, or button press is required.

Quiet for the caregiver

PaShield is designed to provide a meaningful alert rather than a constant stream of raw data.

Personalized over time

The system learns patterns relative to the individual child.

Built for coordination

Caregivers can optionally record what happened and what helped.

Not just an alert

A system that learns.

Signals

Personalized baseline

Recovery pattern

Improved personalization

Feeds back into a more personalized baseline

With optional caregiver feedback, PaShield can begin connecting physiological changes, surrounding context, caregiver responses, and recovery patterns.

Who it helps

Built first for families with high support needs.

PaShield is initially being developed with parents and caregivers of neurodivergent children, including children who are non-speaking, have difficulty communicating distress, or need substantial day-to-day support.

Future versions may support coordinated use across family members, respite caregivers, schools, and therapy teams.

Development status

Built with caregivers, not just for them.

We're building PaShield in direct conversation with parents, caregivers, and professional advisors — not in isolation.

Prototype in active development Caregiver conversations underway Pilot recruitment opening soon Accelerator plans: details to be announced

Specific figures and program details will be added here once confirmed. PaShield has not received clinical validation or regulatory approval.

Join the pilot

Help shape the first PaShield pilot.

We are speaking with parents, caregivers, therapists, researchers, and organizations interested in helping us develop and evaluate PaShield.

  • No medical diagnosis or health history required
  • Takes about a minute to submit
  • We'll only contact you about PaShield

FAQ

Questions caregivers ask first.

PaShield is currently in prototype development. We are recruiting families, caregivers, and professional advisors for early feedback and future pilot testing.

PaShield is being designed to identify personalized physiological and movement changes associated with rising stress. It does not guarantee that every escalation will be detected or that every alert will lead to a crisis.

No. The child's wearable is designed to be screenless and passive.

No. The PaShield Alert Band is designed to provide a discreet vibration when caregiver attention may be helpful.

PaShield is a prototype under development and is not intended to diagnose, treat, cure, or prevent any disease or medical condition.

No. PaShield does not replace caregiver supervision, emergency services, or professional medical care.

PaShield is being designed around data minimization, caregiver control, and secure information handling. More detailed privacy information will be published before pilot deployment.
