Research Institution

NanoGripTech LLC proposes to develop repeatable skin adhesives using technology inspired by the feet of geckos and insects. These adhesives will be integrated into full facemask respirators to reduce or replace head harness straps, which are currently used to hold the facemasks in place. Expected benefits are improved fit, resistance to shifting, improved sealing, and reduced discomfort and tissue damage during prolonged use. A model of the interface between skin and the micro-fibrillar adhesive will be developed to aid in the design and optimization of adhesive design. The proposed effort aims to combine and optimize various fibrillar adhesive technologies into a single system, which exhibits many or all of the unique characteristics of the separate base technologies. Potential technologies that may be incorporated into the final design include tip shapes, directional properties, bio-inspired tip coatings, and hierarchical multi-level geometry. In Phase II of this program we plan to develop a design tool for optimized fiber adhesives, manufacture such optimized fiber adhesives in patches, integrate them to facemasks, and test their sealing and adhesion performance in real world conditions.
