| piezoelectric | Pertaining to piezoelectricity. (05 Mar 2000) |
| piezoelectric effect | The property of certain crystalline or ceramic materials to emit electricity when deformed and to deform when an electric current is passed across them, a mechanism of interconverting electrical and acoustic energy; an ultrasound transducer sends and receives acoustic energy using this effect.

| piezoelectricity | Electric currents generated by pressure upon certain crystals, e.g., quartz, mica, calcite. Origin: G. Piezo, to press, squeeze, + electricity (05 Mar 2000) |
| piezogenic | Resulting from pressure. Origin: G. Piezo, to press, squeeze, + genesis, origin (05 Mar 2000) |
| piezogenic pedal papule | Pressure-induced papules of the heel, occurring probably as a result of herniation of fat tissue. Pruritic urticarial papules and plaques of pregnancy (PUPPP), intensely pruritic papulovesicles that begin on the abdomen in the third trimester and spread peripherally, resolves rapidly after delivery and does not affect the foetus. Split papules, papule's at commissures of the mouth seen in some cases of secondary syphilis. (05 Mar 2000) |
| piezometer | 1. <apparatus, physics> An instrument for measuring the compressibility of liquids. 2. <physics> A gauge connected with a water main to show the pressure at that point. Origin: Gr. To press: cf. F. Piezometre. Source: Websters Dictionary (01 Mar 1998) |
