SUMMARY

This discussion centers on the exploration of nanomaterials with piezoelectric properties, specifically highlighting Polyvinylidene Fluoride (PVDF) as a prominent example. Participants inquire about the potential for engineering these materials to harness energy from surface waves at interfacial boundaries. The conversation also touches on the limitations of current piezoelectric technologies and the potential for further miniaturization and energy harvesting capabilities.

PREREQUISITES
  • Understanding of piezoelectric materials and their properties
  • Familiarity with nanomaterials and their applications
  • Knowledge of energy harvesting techniques
  • Basic principles of dielectric properties in materials
NEXT STEPS
  • Research the engineering applications of Polyvinylidene Fluoride (PVDF) in piezoelectric devices
  • Explore advanced techniques for energy harvesting from surface waves
  • Investigate other nanomaterials with piezoelectric properties
  • Study the dielectric properties of various piezoelectric materials
USEFUL FOR

Researchers, materials scientists, and engineers interested in nanotechnology, energy harvesting, and the development of advanced piezoelectric materials.

My apologies in advance for ignorant questions.

Are there any nanomaterials that exhibit piezoelectric properties ? Can they be engineered to take energy from surface waves at interfacial boundries ? I only ask after seeing the recent article on piezielectric vibration " harvesters " on the Physorg fron page lead me to wonder why this technology has not been shrunk further ? Or is it such a small amount of energy in most cases it's overlooked ?

Is there still plenty of room at the bottom ?
 
Engineering news on Phys.org
yes there are. i do not know of all of them but the one i know best is Polyvinylidene Fluoride (PVDF). I have been experimenting with the stuff for quite a while but need some more info before i get the stuff to work. but from what i have read, it produces the biggest dielectric properties of almost all the other types of piezoelectric materials.
