Strain energy accumulators utilize the hyper-elastic behavior of elastomers and their large strain percent and energy density to store energy. Current research is focusing on quantifying the efficiency of the device at both the component and system levels. Longer term we are looking to develop a carbon nanotube elastomer for use in the strain energy accumulator that will increase elastic modulus, minimize hysteresis, provide electromagnetic shielding and strain sensing capabilities. The addition of carbon nanotubes will increase the potential applications of the strain energy accumulator.
