Precision fluid transfer and controlled wetting via micro-textured surface systems

Overview

The proposed technology is a precision micro-fluidic handling and dry-mist atomization platform designed for controlled fluid transfer across surfaces, especially elastomeric and silicone interfaces. It replaces passive capillary flow with active micro-dosing and high-frequency ultrasonic surface detachment, addressing common problems such as fluid pinning, unwanted surface accumulation, and residual wetting. The result is clean, directional fluid delivery with minimal residue and reduced risk of cross-contamination.

The system is packaged as modular micro-dispensing and dry-mist generation units suitable for OEM integration and technology licensing. It can atomize liquids and essential oils into an ultra-fine aerosol/dry mist without leaving liquid residue, surface pinning, or oily buildup on surrounding channels.

Technical specifications

Core features:

• Piezoelectric ultrasonic cavitation generates an ultra-fine aerosol/dry mist at the liquid-surface boundary.
• Active PWM micro-dosing enables precise micro-liter dose control.
• Dedicated Wet Zone isolation separates the fluid containment area from surrounding channels.
• Backflow prevention and active airflow management ensure immediate clearing and controlled directional transfer.
• Operating parameters, including ultrasonic frequency and PWM dosing logic, can be tuned for target fluid viscosities.
• Reported surface friction coefficient range for evaluation: 0.4–0.6.

The architecture includes a validated bill of materials and is designed for production-ready manufacturing. It is particularly relevant for applications requiring long-term surface hygiene, precise dosing, and clean handling of low-volume liquids on challenging polymer surfaces.

Technology readiness level

The technology has reached a fully functional MVP stage with a proven bill of materials and international patent protection. It is ready for comparative evaluation on target silicone substrates, with a defined engagement roadmap covering technical onboarding, test coupon integration, performance validation, and commercial licensing/technology transfer. The current focus is on fine-tuning operating parameters for specific fluid viscosities and validating performance on silicone substrates.
