- Medical headgear
See how friction-based bonding replaces adhesive to reduce NICU noise while securing respirator
- Elongated Wrist Towel Structure for Low-Pressure Adjustable Fit
An elastic distal rim and longitudinal seam keep the wrist towel secure while allowing adjustable coverage without full-arm compression.
- MEA Steam Concentration Converter for Low-Grade Heat Harvesting
Uses an ion-conductive MEA to turn water vapor pressure differences into power, avoiding inefficient thermoelectric temperature gradients.
- Steam Concentration Cell Using MEA Membranes for Low-Grade Heat Power
Uses water vapor pressure differences across MEA membranes to generate power from low-grade heat with less complexity than thermoelectrics.
- Hydrophilic Dermal Heatsink Coating for Evaporative Cooling
A porous hydrophilic coating wicks sweat through a dermal heatsink while resisting contaminants to improve evaporative body cooling.
- Wearable Cooling Insert With Wicking Heatsink Grid Structure
A grid-mounted heatsink wicks skin moisture for evaporative cooling while a flexible polymer frame improves fit, durability, and replaceability.
- Hydrophilic Dermal Heatsink Coating for Oil-Resistant Evaporative Cooling
A porous hydrophilic coating wicks sweat for evaporative skin cooling while resisting oil contamination through controlled pore filtration.
- Multifunctional Hair Band Structure for Workout Accessory Merging
A stitched dual-layer elastic band combines hair control and resistance exercise functions to cut workout clutter while staying durable.
- Three-Strap HMD Headband for Secure, Comfortable Wear
A three-strap headband with internal passageways and elastic tension secures mounted electronics for long HMD use without sagging or discomfort.
- Protective Headband Inserts for Targeted Impact Protection
Strategically placed inserts add head protection at vulnerable impact zones while keeping a slim, comfortable fit for sports use.
- Layered Sweat Wicking Structure for Dry, Odor-Free Absorption
A hydrophobic outer layer, hydrophilic inner layer, and absorbent core manage heavy sweat while staying drier and less odorous.
- Bladeless Headband Fan for Wearable Sweat Evaporation Cooling
Internal fans and Peltier cooling in a wearable headband boost sweat evaporation and airflow without bulky external power.
- Detachable Beanie Band for Multi-Use Wear and Compact Storage
A detachable beanie band uses fasteners and elastic straps to switch between hat trim, scarf, mask, and sweatband with secure storage.
