摘要： A method for fabricating scanning probe microscopy (SPM) probes is disclosed. The probes are fabricated by forming a structural layer on a substrate, wherein the substrate forms a cavity. A sacrificial layer is located between the substrate and the structural layer. Upon forming the structural layer, the sacrificial layer is selectively removed, and the probe is then released from the substrate. The substrate may then later be reused to form additional probes. Additionally, a contact printing method using a scanning probe microscopy probe is also disclosed.

摘要： A material deposition sensor includes a heater (24) and a temperature sensor (30) separated from one another. In operation, the sensor is disposed within a deposition chamber, and material is deposited onto the sensor. When a particular material thickness is deposited, a direct thermally conductive path is created between the heater and temperature sensor, and heat from the heater conducts directly to the temperature sensor. By predetermining a deposition thickness necessary to create the direct thermally conductive path, the deposition thickness can be controlled and/or predicted.

摘要： A microfluidic system includes one or more functional units (30, 32, 34, 36, 300, 302, 304, 306, 400) or microfluidic chips, configured to perform constituent steps in a process and interconnected to form the system. A multi-layer microfluidic system includes a separate dedicated fluid layer (402) and dedicated electromechanical layer (404) connected via through-holes (410). Electromechanical components (412) are formed on the electromechanical layer.

摘要： A probe array for includes a handle, a first probe and a second probe. The first probe has a first shank, connected to the handle, and a first tip; and the second probe has a second shank, connected to the handle, and second tip. The first tip contains a different material from the second tip. The probe array may be used to write on a surface by contacting the first tip with a surface, where a first ink is on the first tip. This writing method may further include lifting the first tip from the surface and contacting the second tip with the surface.
