During the new study, the experimental physicist Xin Wen froze salt water in silicone forms with his colleagues. As a result, the ice appeared either in the form of a cone or a curved beam. Later, scientists used a special device for multiple bending of salt castings and measured an electrical charge. The cones are based on heavy loads and gave more stress. At the same time, small cones can withstand more deformation than they are large.
According to Van, the installation of arrays from many small cone can help increase the total output capacity.
Although it is quite possible to use salt ice on cheap sensors or energy collection devices, scientists are still far from the ability to supply daily gadgets in this way. For example, to charge a smartphone, you may now need a piece of ice between a few ten to one hundred square meters.
