Deformation Sensing in Soft Bio-Surrogate Materials
Abstract
This report provides a detailed overview of the research findings performed to advance deformation sensing in soft materials including: 1)investigation of conductive liquids and matrix materials to enable impedance matched resistive sensors; 2) details on a custom electronics package with the necessary resolution to resolve the changes in resistance with deformation; 3) development and characterization of three rapid fabrication techniques used to generate the embedded channels for resistive, liquid metal sensors; 4) details of the gage assembly method including the encapsulation and filling of the embedded channels; and 5) experimental results from cyclic stretching of prototype soft strain sensors made using the three fabrication methods, as well as a 2-dimensional rosette-style gage and the use of conductive thread for the sensors electrical leads.
