    Abstract: A photoelectrical device for detection of bacterial cell density includes a substrate, a driving electrode layer, an AC power source and a photoelectric conversion layer. The driving electrode layer is disposed on the substrate and includes a central electrode and a peripheral electrode pattern surrounding the central electrode. A fluid sample is disposed on the driving electrode layer. The AC power source is electrically connected to the driving electrode layer, and used to produce a non-uniform alternating electric field in the fluid sample on the driving electrode layer for driving the target bioparticles to gather up on the central electrode to form a particle cluster. The photoelectric conversion layer is used for receiving a light detecting beam after passing through the particle cluster and outputting an electric current based on the optical density of light detecting beam. The electric current changes as a concentration of the target bioparticles changes.

    Abstract: The geometrically nonlinear isolation system of the present invention includes a bearing platform, an isolator and a damper. The isolator is connected with the bearing platform and used for providing resilience against horizontal relative displacement between the bearing platform and the isolator. The damper is pin-jointed to the bearing platform and has an axis orthogonal or oblique to the horizontal direction. Accordingly, when the bearing platform and the isolator move with respect to each other along the horizontal direction, the angle between the axis of the damper and the horizontal direction would change with the horizontal displacement, and the damper provides damping force along a direction parallel to the axis of the damper so as to enhance horizontal vibration isolation effect.

    Abstract: The vertical vibration isolation system of the present invention includes a bearing base, a guide rail assembly and a plurality of buckling elements. The bearing base has an upper platform that can move along a vertical direction. The guide rail assembly surrounds the bearing base and has a plurality of arc-shaped sliding channels. The top portion of each buckling element can move with the upper platform, while the bottom portion of each buckling element is slidably connected to the corresponding arc-shaped sliding channel. The vertical displacement of the upper platform would cause different degrees of buckling of the buckling elements and also induces sliding motion of the bottom portion of the buckling elements along the arc-shaped sliding channels. Accordingly, the vertical vibration isolation system can provide nonlinear restoring force by buckling and sliding mechanisms so as to exhibit vertical vibration isolation effect.

    Abstract: The optical fiber sensing method of the present invention includes steps of: joining heat shrinkable tubes to two ends of a sensing segment of an optical fiber; coupling a fixing element on the heat shrinkable tube below the sensing segment; detachably connecting at least one floating element to the fixing element; placing the floating element into a fluid; and providing an input signal to the sensing segment and generating an output signal after the input signal is processed by the sensing segment, wherein the tensile force applied to the sensing segment would change with variation of the buoyant force upon the floating element, resulting in change of the output signal. Accordingly, the optical fiber sensing method has numerous advantages, including rapid on-site construction, recyclability of components and changeability of design parameters.
