Pressure sensing is challenging in liquid environments, where typical solid-state sensors do not perform well. A sensor with solid–liquid–liquid–gas multiphasic interfaces — its design inspired by the lotus leaf, and in which a trapped air layer modulates capacitance changes with pressure — is shown to achieve near-ideal pressure sensing and is well suited to liquid environments.
