Hard vs Soft Fibrillar Self-Cleaning

My paper on the self-cleaning of gecko adhesives was published in Applied Materials and Interfaces. We reported that for certain particle sizes and fiber diameters, both hard (polypropylene) and soft (PDMS) fibrillar adhesives recover adhesive capabilities to...

Magnetically Actuated Ridges

My recent work on magnetically actuating an array of microridges has been published in Advanced Functional Materials. We have shown that by controlling the angle of the 325 micron long array elements, we can controllably adhere to a range of particle sizes. Here is a...

Dynamic Climbing Robot

Paul Birkmeyer and I have created a version of his CLASH robot that now includes footpads with synthetic gecko adhesive. CLASH can now rapidly climb steep acrylic up to angles of 75 degrees. Our work was published at IROS...

CLASH: Climbing Vertical Cloth

My work on Paul Birkmeyers CLASH robot has been published in IROS 2011. During the development of CLASH, I assisted by testing the engagement properties of the feet on loose cloth substrates using a custom built 2 axis force displacement apparatus. Testing revealed...

Shear limits of thermoplastic gecko-inspired adhesive

Our work on the wear and high-cycle properties of gecko synthetic adhesives has been published in Langmuir. We examined the behavior of high-density polyethylene (HDPE) and polypropylene (PP) microfiber arrays during repeated cycles of engagement on a glass surface,...
