Underwater thrust and power generation using flexible piezoelectric composites: an experimental investigation toward self-powered swimmer-sensor platforms (2011, background): “8 When performing an experiment to charge a battery by using the harvested energy, it is essential to check the discharge curve [65, 66] since plotting the voltage associated with charging alone [67, 68] can be misleading in respect of the amount of charge received by the battery.”
Energy harvesting through a backpack employing a mechanically amplified piezoelectric stack (2008, background): “Later, Sodano et al. [6, 7 ] performed a series of studies investigating the use of an electrochemical battery as the energy storage device.”
On the efficiency of piezoelectric energy harvesters (2017, neutral): “5% PZT; flextensional structure; direct deformation; experimental data [31] >80% PZT; fixed–fixed bimorph plate; theoretical estimation [32] ∼7% PZT; cantilever; vibration; experimental data [33] 0.”
