Product Description Specifications Downloads Quote / Order

PI P-878 Drawing, DuraAct Power Multilayer Patch Transducers use the longitudinal or d33 effect, which describes an elongation parallel to the electric field E and the polarization direction P of the piezo actuator. The d33 piezoelectric charge coefficien

Useable as actuator, sensor or energy generator
Low voltages to 120 V
Compact design
Individual solutions

Functionality as actuator and sensor component. Nominal operating voltages of -20 to 120 V. Power generation for self-sufficient systems possible up to the milliwatt range. Can also be applied to curved surfaces.

In longitudinal direction, the DuraAct Power uses the high-efficiency d33 effect

Laminated structure consisting of PICMA® multilayer piezo element, electrodes and polymer materials. Manufactured with bubble-free injection method. The polymer coating simultaneously serves as electrical insulation and as mechanical preload, which makes the DuraAct bendable

Flexible choice of size
Variable design of the electrical connections
Combined actuator / sensor applications, even with several active piezoceramic layers
Arrays

Industry and research. Can also be applied to curved surfaces or used for integration in structures. For adaptive systems, energy harvesting, structural health monitoring

Preliminary data	P-878.A1	Unit
Min. axial strain	1200	µm/m
Rel. axial strain	10	µm/V
Min. lateral contraction	250	µm/m
Rel. lateral contraction	1.2	µm/V
Blocking force	44	N
Dimensions	27 mm × 9.5 mm × 0.5 mm
Min. bending radius	24	mm
Active element	15 mm × 5.4 mm
Electrical capacitance	150	nF

Angabe der Dehnungs/Kontraktionsrichtung axial/lateral sollte einheitlich mit P-876 Wandlern sein! Dort wird allgemein über laterale Kontraktion gesprochen.

BSc, 10.10.2013: bei p-876 gibt es nur eine Kontraktion in lateraler Richtung; die Ausrichtung ist in der Grafik im Datenblatt verdeutlicht. P-878 dehnt sich zusätzlich in Richtung der Polarisationsachse -> s. Zeichnung. Ist dadurch ebenfalls eindeutig.

Electrical capacitance: Tolerance ±20 %, measured at 1 V_pp, 1 kHz, RT.

Piezo ceramic type: PIC252.

Standard connections: Solderable contacts.

Operating voltage: -20 to 120 V.

Operating temperature range: -20 to 150 °C.
