Evaluation of Synthetic Setae Pads for Dry Attachment of an Ultrasound Transducer

Abstract

Medical ultrasound requires the coupling of skin with the transducer. Removing this requirement could make ultrasound stimulation and imaging more accessible and convenient. Synthetic setae pads are a biomimetic material that mimics the structure of a gecko’s foot, allowing it to hold substantial weight. The attenuation of 10MHz and 5 MHz ultrasound through commercially available synthetic setae pads were evaluated.
