Abstract: Disclosed is a microfluidic detection device including a circuit substrate and a transparent substrate. The circuit substrate is provided with at least one first light-emitting device used to emit a detection beam, a photodetector used to receive the detection beam and send out a sensing signal, and a control circuit electrically connected to the first light-emitting device and the photodetector. The transparent substrate overlaps the circuit substrate and is provided with a microfluidic channel and a light guide structure. The light guide structure has a light incident surface disposed corresponding to the first light-emitting device and a light exiting surface disposed corresponding to the photodetector. The light guide structure extends from each of the light incident surface and the light exiting surface to the microfluidic channel and is adapted to transmit the detection beam into and out of the microfluidic channel.

Abstract: A heating device includes a first capacitor, a first switch, a second switch, a second capacitor, a third capacitor, a coil and a controller. The first and second switch are coupled in series at a first node, and are coupled with the first capacitor in parallel. The second capacitor is coupled to the first switch. The third capacitor is coupled to the second switch, and is coupled to the second capacitor at a second node. The coil is coupled between the first and the second node. The controller outputs a first and a second control signal to the first switch and the second switch, respectively. After the heating device received a voltage and a starting command, the controller outputs the first and the second control signal to turn on or off the first and the second switch respectively. The duty cycle of the first signal is lower than 50%.

Abstract: A nanoscale motion apparatus includes a fixed base, a movable platform, and means for moving the movable platform connected between the fixed base and the movable platform. A sensing device includes a holder, at least two nanosensors, and a measurement plate. The holder is mounted on the fixed base. The nanosensors are configured on the holder. The measurement plate is mounted on the movable platform. The measurement plate can be sensed by the nanosensors so as to measure the corresponding variation between the fixed base and the movable platform.

Abstract: A piezoelectric linear motor apparatus and method is provided. The apparatus comprises a carriage configured to be actuated and a stator configured to actuate the carriage. The stator comprises a meander line structure and a gear teeth structure, coupled to the top of the meander line structure and a contact layer underneath the carriage. Furthermore, the meander line structure comprises a series of bimorph actuators laid linearly in the meander line structure. Each pair of neighboring bimorph actuators being linked with a corresponding connector on both sides of top and bottom. The meander line structure also comprises an odd series of connectors and an even series of connectors, interleaved with each individual connector, applied with phase-splitter's alternating current (AC) power to deform the bimorph actuators for generating traveling wave. The gear teeth structure is configured to transport traveling wave from the meander line structure to the carriage.
