    摘要: Embodiments of the present invention provide a new method for producing a three dimensional object, particularly suited to microfabrication applications. The method includes the steps of providing a substrate with a conducting interface, an electrode having a feature or features that are small relative to the substrate, and a solution. The solution has a reactant that will either etch the substrate or deposit a selected material in an electrochemical reaction. The electrode feature is placed close to but spaced from the interface. A current is passed between the electrode and the interface, through the solution, inducing a localized electrochemical reaction at the interface, resulting in either the deposition of material or the etching of the substrate. Relatively moving the electrode and the substrate along a selected trajectory, including motion normal to the interface, enables the fabrication of a three dimensional object. In an alternative embodiment, current is passed through an orifice placed close to but spaced from the substrate surface, and may be accompanied by forced convection through the orifice. The method provides the potential to fabricate using many materials, including metals, alloys, polymers and semiconductors in three dimensional forms and with sub-micrometer spatial resolution.

    摘要: A rotary actuator for applying torque to a crank with respect to a member. The rotary actuator has a substantially planar sheet of anisotropic conducting polymer, portions of which are activated in temporal sequence to produce rotation of the crank with respect to the axis of the crank. Actuation is achieved by contraction of successive portions of the sheet as electrical current causes differential strain in the sheet.

    摘要: The synthesis of thiophene based conducting polymer molecular actuators, exhibiting electrically triggered molecular conformational transitions is reported. Actuation is believed to be the result of conformational rearrangement of the polymer backbone at the molecular level, not simply ion intercalation in the bulk polymer chain upon electrochemical activation. Molecular actuation results from π-π stacking of thiophene oligomers upon oxidation, producing a reversible molecular displacement that leads to surprising material properties, such as electrically controllable porosity and large strains. The existence of active molecular conformational changes is supported by in situ electrochemical data. Single molecule techniques have been used to characterize the molecular actuators.

    摘要: A method for driving an actuator. The method includes applying an electrical potential across an electrostrictive material relative to a counterelectrode disposed within an electrolyte, thereby creating a double layer potential across a region of enhanced ionic concentration. A current flowing between the electorostrictive material and the counterelectrode is measured. A portion of the applied potential appearing across the electrolyte and counterelectrode is calculated and subtracted from the applied potential to obtain an estimated double layer potential. The applied electrical potential is adjusted to obtain a specified double layer potential.

    摘要: An apparatus and method wherein speech or other signals are sampled during a time slice of approximately 1/30 second and spectrum analysis is performed on the samples, producing measures of amplitude in several frequency bands with each frequency band being characterized by a binary digit indicating the presence or absence of significant amplitude. The binary digits are collectively referred to as a sonogram. Sonograms for several time slices are then concatenated, randomized and decoded using an n-tuple technique to produce a pattern corresponding to the current speech signal. This pattern is learned by superimposing it on an existing vocabulary entry and is subsequently recognized if it is sufficiently similar to one vocabulary entry and different from all others.
