  • Publication number: 20210364489
    Abstract: Example implementations include a sensor device with a superhydrophobic sensor panel having an abraded first planar surface and a second planar surface opposite to the first planar surface, and a metallic heating element adjacent to the second planar surface of the superhydrophobic sensor panel. Example implementations also include a method of detecting a concentration of heavy metal ions in a solution, by separating a target solute of a target microdroplet from the target micropdroplet, identifying a distribution area of at least one heavy metal ion in an image of the target solute, generating a heavy metal ion concentration quantity based on the distribution area, generating a composite image including an indication of the distribution area, and presenting an indication of at least one of the heavy metal ion concentration quantity and the composite heavy metal ion image.
