Background sensing. Actionable alerts.

A skin-adaptive wearable sensor that monitors VOCs, sweat biomarkers, and temperature, then alerts only when meaningful changes appear.

About

Philtrum is a new kind of company fusing wearable sensing, soft materials, and machine intelligence.

We translate subtle chemical and physiological shifts into discreet, action-ready cues.

Signals Loop

Sense, Understand, Respond.

One continuous chain from ambient and skin inputs to discreet, meaningful cues.

Sense

Airborne chemistry, sweat biomarkers, and skin temperature tracked passively all day, without manual sampling.

Understand

Correlates signal patterns to known baselines, identifying, for example, elevated cortisol markers alongside a CO₂ spike.

Respond

A soft haptic, thermal, or olfactory cue when a change requires attention. Nothing on a screen unless you ask for it.

Signal Flow

Always on, quietly adaptive.

The model continuously interprets context and surfaces a cue only when attention is warranted.

Use Cases

Built for real-world conditions.

From daily wellness to occupational safety and clinical research, the system adapts to context without adding friction.

Wellness · Daily Life

Detects the CO₂ and VOC buildup that degrades sleep quality, before you wake up groggy and can't explain why.

Workplace · Occupational

Alerts lab and kitchen workers to airborne risk shifts before symptoms appear: continuous, wearable, no fixed sensors required.

Health · Clinical Research

Replaces intermittent blood draws with continuous skin-fluid biomarker data: longer studies, higher compliance, richer longitudinal signal.

Platform Readiness

Evidence package, ready for review.

Controlled-lab validation across 150+ chemical signal classes
Sample Data Package Pilot Protocol Draft Integration Checklist Regulatory Review Path IP Filing Submitted

Qualified partners receive a signal matrix, onboarding checklist, and implementation constraints before kickoff.

Why This Approach

Signal processing happens entirely on-device. Nothing is transmitted unless you initiate a sync. No identifiable data leaves the film under default settings.

Common Questions

A skin-adaptive sensing film that passively monitors airborne chemistry, sweat biomarkers, and temperature, then escalates only when changes are meaningful.

A stretchable, skin-adaptive hydrogel continuously monitors breath-borne VOCs and subtle skin cues. It compares shifts to your baseline, then delivers scent, thermal, haptic, and fit cues only when action is needed. You feel the alert quickly, without checking a screen.

Continuous, passive collection: Built for teams that can't miss a threshold.
Meaningful-change alerts: Reduces noise without hiding signal.
Designed for wear-time comfort: Skin-adaptive form factor for long runs.

Processing is on-device by default. No identifiable data leaves the film unless you explicitly sync, and pilot reporting is shared as aggregate patterns.
