  • Publication number: 20180306702
    Abstract: Provided are a device and method for measuring mechanical properties of a cell, the device including: a substrate layer (2); and a nanowire layer (1) arranged on the substrate layer (2) and including a nanowire array, nanowires (11) in the array are configured to emit an light signal, and in response to a cell (3) to be tested being placed on the nanowire layer (1), a change in the light signal emitted by the nanowires (11) supporting the cell to be tested (3) represents mechanical properties of the corresponding cell. Mechanical properties of a cell can be measured in real time according to a change in the light signal emitted by the nanowires.

  • Patent number: 7771846
    Abstract: An ME composite laminate of at least one (1-3) piezo-fiber layer coupled with high-permeability alloy magnetostrictive layers, optionally formed of FeBSiC or equivalent. The composite laminate alternates the (1-3) piezo-fiber and high-permeability alloy magnetostrictive layers in a stacked manner. Optionally, the magnetization direction of the high-permeability alloy magnetostrictive layers and polarization direction of the piezo-fiber layer are an (L-L) arrangement. Optionally, thin film polymer layers are between the (1-3) piezo-fiber layer and high-permeability alloy magnetostrictive layers. Optionally, piezo-electric fibers within the (1-3) piezo-fiber layer are poled by inter-digitated electrodes supported by the thin film polymer, arranged as alternating symmetric longitudinally-poled “push-pull” units.
