Noliac Technical Note on Shear Mode Actuators
(Nanowerk News) Aging under high field, hysteresis and impedance spectrum for shear actuators are covered in a new technical note for download. Tests were performed in Noliac Motion on standard CSAP02 actuators (5 x 5 x 0.5 mm). Other standards (CSAP01, CSAP03) give similar results.
Shear plate actuators
Among other findings, tests regarding aging under high field showed interesting results. Above the maximum recommended voltage, shear actuators degrade following a logarithmic trend with regards to the number of cycles.
This feature is of importance, since it can allow driving the actuators with higher performance if only a few cycles are required.
