Overview

Experimental study demonstrates optical bending characterization in planar dielectric elastomer actuators, highlighting their potential for developing low-voltage artificial urinary sphincters.

Key Points

To quantitatively measure the bending behavior and mechanical stress of asymmetric planar dielectric elastomer actuators across varying substrate thicknesses and electric fields.
Fabricated asymmetric micro-cantilevers using 1 or 5 μm-thin silicone dielectric elastomer actuators mounted on polyethylene naphthalate substrates with thicknesses of 16, 25, 38, or 50 μm.
Measured voltage-induced substrate bending using an optical beam deflection setup while applying electric fields up to 80 V/μm.
Detected bending radii as large as 850 m with reproducible optical beam deflection measurements.
Observed electrode conductivity degradation and structural mechanical failures at high electric fields approaching 80 V/μm.
