Smart Metamaterial

Engineering & Applied Science (College of) / Civil & Environmental Engineering

Project Description

Develop a smart metamaterial (shapeshifting material like an octopus arm) capable of strains greater than 10%. The base material is a piezoelectric polymer, PVDF, that is capable of only 0.1% strain when subjected to an electric field. The polymer is laser machined into special shapes to mechanically amplify the strain. At the present time, the devices have exhibited up to 6% strain. Plans are in place to increase that strain well above 10% and hopefully reach 100% (double in size).

Tasks and Responsibilites

The student will characterize the piezoelectric properties of PVDF. The sole manufacturer provides limited information and a large range for the properties that are reported. At present, the student is using strain gauges. Other, less invasive techniques are also being pursued. Once the data is obtained and incorporated into a model being developed by a different group, the student will help to write a research paper on the findings. Afterwords, the student will continue to help the PI develop the technology by inventing ways to increase the strain capability and force output of the material. Specifically, the student will design, build and test new prototypes.
