摘要： An electrostatic driving apparatus for a microactuator is provided, in which a parasitic capacitance is offset to improve the performance thereof. According to the complementary electrostatic driving apparatus for the microactuator, in order to prevent an excitation signal from being mixed with a sensing signal via the parasitic path formed of parasitic capacitance according to the structure of the microactuator and vibration characteristics thereof, which cause noise, signals having opposite polarities are applied to activating vibration plates using an inverter such that the activating vibration signals of each plate, which cause noise, are offset, thereby markedly improving the signal-to-noise ratio. Also, the vibration displacement can be easily detected by a circuit which is not integrated with an actuator. In addition, a sensing unit is simplified, reducing the initial costs. Further, when the excitation signals are applied at the both sides of the vibration direction of the suspended vibration plate, only the AC component, i.e., the .omega. component, of the electrostatic force acts, so that the resonant characteristics can be improved without an offset of the displacement.

摘要： A thermally-driven ink-jet printhead includes a substrate having an ink chamber to be filled with ink to be ejected, a manifold for supplying ink, and an ink channel for providing flow communication therebetween. First and second sidewalls are formed to a predetermined depth from an upper surface of the substrate and define the ink chamber to have a substantially rectangular shape. A nozzle plate including a plurality of material layers is formed on the substrate. A nozzle passes through the nozzle plate and is in flow communication with the ink chamber. A heater is disposed between the nozzle and one of the first sidewalls above the ink chamber. A conductor is electrically connected to the heater. The conductor and the heater are disposed within the nozzle plate. A shifting feature moves cavitation points beyond an outer edge of the heater.

摘要： A polymerase chain reaction apparatus includes: a substrate; a high-temperature sidewall erected on the substrate; a low-temperature sidewall erected on the substrate and facing the high-temperature sidewall; and a reaction chamber consisting of the substrate, the high-temperature sidewall, and the low-temperature sidewall, wherein a sample contained in the reaction chamber is repetitively thermal-circulated between the high-temperature sidewall and the low-temperature sidewall using Marangoni convection generated by a surface tension gradient resulting from a temperature difference in an interface between the sample and air. The PCR amplification can be automatically accomplished by surface tension flow generated by Marangoni convection resulting from a temperature difference in an interface between the sample and air when a temperature difference between the sidewalls of the chamber is maintained constant. As a result, it is possible to reduce power consumption, simplify the configuration of a temperature control circuit, and reduce the time for a cycle of amplification.
