But for these devices to efficiently generate sonar or ultrasound waves, the material needs to be \u201cpoled.\u201d<\/p>\n<p>That\u2019s because the piezoelectric materials used for sonar and ultrasound applications are mostly ferroelectric. And like all ferroelectric materials, they exhibit a phenomenon called spontaneous polarization. That means they contain pairs of positively and negatively charged ions called dipoles. When a ferroelectric material is poled, that means all of its dipoles have been pulled into alignment with an external electric field. In other words, the dipoles are all oriented in the same direction, which makes their piezoelectric properties more pronounced.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Heat and pressure can deteriorate the properties of piezoelectric materials that make state-of-the-art ultrasound and sonar technologies possible \u2013 and fixing that damage has historically required disassembling devices and exposing the materials to even higher temperatures.
