Abstract:
A piezoelectric actuator includes a thin film sheet, a first electrode, and a second electrode. The thin film sheet is to physically deform in response to an electric field induced within the thin film sheet. The first electrode is embedded within the thin film sheet. The second electrode is embedded within the thin film sheet, and is interdigitated in relation to the first electrode. The electric field is induced within the thin film sheet via application of a voltage across the first and the second electrodes.
