Methods

Developing multielement doped Pb-free (K,Na)NbO₃ piezoelectrics often hindered by complex doping trends and tedious trial-and-error experimentation.

Results

~705μW/cm3

Power density generated by the harvester, higher than other reported lead-free energy harvesters.

More results

Using collaborative strategy, synthesized random composition exhibiting piezoelectric charge constant d 33 of 440 - 500 C/N which further enhanced to 600-620 C/N through crystallographic texturing and sintering aid optimization.

Despite inherently off-MPB degradation (at R.
