Sensing and Modulating Materials Properties Using Piezo-Electric Response Elements
Abstract
Polymer composites experience unique and often complex stress fields. To date, these stresses have been mitigated by creating polymers with greater tolerance to failure or through self-healing mechanisms implemented after the onset of damage. In each case, the composite remains uniform, despite experiencing non-uniform stress fields. Moreover, each composite experiences an individual and unique set of stress fields. We propose to develop techniques that extend self- healing beyond mechanical damage into a regime of self-improvement where each material can adapt to its unique stress field. In this program, our vision is to develop materials that alter their modulus in response to mechanical load, sensing the degree of alteration and adjusting their conditions - a material that senses its environment and adjusts its properties. This methodology is synergistic with our other efforts in this field - controlling morphogenetic remodeling with reaction/diffusion - as it provides a unique mechanism for control of these process, while bringing in novel methodologies of enabling CPU driven control of materials properties and the potential for CPU guided morphing of materials.
