Use Cases in Wearable Medical Devices

Smart-watch health monitor

Ultra-thin bioglass protects PPG sensor window.

CGM patch

25 mm tear-drop glass lens, < 1 mm total height.

Rehab brace

0.3 mm UTG display for motion analytics, sweat-proof.

Building a PPG Sensor Window for Wearable Medical Devicesa

Base Glass

Corning® Willow® / AGC Xensation® UTG .

We start with biocompatible ultra-thin glass—0.3 mm Corning® Willow® or AGC Xensation® UTG—delivering ISO 10993 skin safety and drop resistance.

Coating Stack

Dual AR/AF + nano Parylene-C.

Dual AR/AF plus a nano-scale Parylene-C barrier keep the ISO 10993 thin glass window clear, oil-free and sweat-proof for 24 × 7 wear.

Vacuum Bond

Airtight IP68, + 88 % outdoor contrast.

UV-cured OCA creates an IP68 seal and boosts outdoor contrast by 88 %, locking the bio-compatible UTG to the sensor PCB without bubbles.

Smart Electrodes

ITO / Ag-mesh extends ECG pickup.

Printed ITO / Ag-mesh on the rear side extends ECG pickup across the medical-grade ultra-thin glass with < 10 Ω/□ sheet resistance.

EU Compliance

Full ISO 10993 & REACH files

Every window ships with ISO 10993 biocompatibility data, REACH substance reports and CE-ready risk files—accelerating regulatory sign-off.
