To optimize piezoelectric harvesting with plastic films, the team deployed an analytical approach.
The researchers are now trying to determine which factors — substrate type, film thickness or crystal composition and position — influence the film's piezoelectric potential the most, Zeches says.
The researchers report finding a viable alternative in specially prepared bismuth ferrite film that has piezoelectric properties on par with lead - based compounds.
Rather than relying on a strain or an electrical field, the researchers incorporated zinc oxide nanoparticles into a PVDF thin film to trigger formation of the piezoelectric phase that enables it to harvest vibration energy.
Other recent research areas have included the structural characterization of lattice - mismatched epitaxial metal films on oxide substrates for radiation damage studies, and the development of new complex oxides as high temperature, radiation - resistant piezoelectrics for use in advanced in situ sensors.
While it is too soon to say if bismuth ferrite - based substances can replace lead entirely, there is potential, and the researchers are now working on figuring out which variables to tweak to maximize the film's piezoelectric potential.
