Soft Materials Laboratory

The purpose of this project is to construct a voltage controlled artificial excitable cell fabricated from electro-active polymers. Polymers with the ability to change their ionic permeability in response to voltages are used as an ion gate in the design of a biomimetic excitable cell, through which ion species flow to produce distinct activated and resting phases, as foundin the biological cardiac myocyte. The grand vision of this research initiative is to connect the gel-cells into a large array to produce the first engineered excitable medium, an electro-active polymer analogy to heart tissue. Engineered excitable media have numerous potential applications including: 1) a new research approach to help elucidate the relationship between cardiac geometry and arrhythmias, 2) a bio-inspired peristaltic tube pump, and 3) a new class of artificial muscle.
