“…Curved piezoelectric structures exhibit differences in strain mode, charge distribution and material requirements compared to other piezoelectric structures. Lee et al [17] found that the lightweight piezocomposite unimorph actuator (LIPCA-S2) with a cantilever length of 65 mm achieves a maximum tip displacement of 15.2 mm, with an average inverse piezoelectric constant of 1100 pm/V. Given its lightweight and small size, LIPCA-S2 could be used in aerodynamic-related fields such as spacecraft wing section control and small missile guidance.…”

Electrophoretic Deposition of Rochelle Salt Nanocrystals on Aluminum Plate

A straightforward and inexpensive electrophoretic method for obtaining environment-friendly nanocrystalline piezo layers from Rochelle salt (RS) is presented here. The electrophoretic deposition process includes the formation of nanocrystals by precipitation of Rochelle salt/water solutions in ethanol (anti-solvent method) under the influence of a high electric field. A nanoporous anodic aluminum oxide membrane is used to separate the electrochemical cell into two chambers. The composition of the RS:H2O:EtOH mixture and the spatial separation of the process of precipitation from electrophoretic deposition allow control of the nanocrystal size and the uniformity of the layer. The reaction kinetics, the morphology, and the piezo response to the resulting layers are all investigated. The best samples were obtained at RS:H2O:EtOH ratio 1:22.5:37.5. Under these conditions, the nanocrystals are preferentially oriented on the aluminum substrate and form a dense and homogeneous layer. Although the obtained structure is polycrystalline, the resulting piezo effect is 1120 pC/N, which is comparable to inorganic monocrystals and piezoceramics. This allows the use of electrophoretically deposited polycrystalline piezo layers in applications such as energy harvesting.
