Figure 5From: Lead-free LiNbO3 nanowire-based nanocomposite for piezoelectric power generationStability of the LiNbO 3 -PDMS composite nanogenerator. (a) Cycling number-dependent open-circuit voltage and closed-circuit current of the LiNbO3-PDMS composite nanogenerator. (b) Dielectric constant and (c) current–voltage (I-V) characteristics before and after 105 cycles of excessive strain.Back to article page
