    Abstract: An improved scanning tunneling microscope comprising a semiconductor chip into which slots are etched to form a central portion linked by a first pair of stripes to an intermediate portion, which in turn is linked by a second pair of stripes to the main body of the chip. The pairs of stripes have mutually orthogonal directions to allow the center portion to perform movements in the x- and y-directions under the control of electrostatic forces created between the stripes and their opposite walls. The center portion has formed into it at least one tongue carrying an integrated, protruding tunnel tip which is capable of being moved in the z-direction by means of electrostatic forces between said tongue and the bottom of a cavity below the tongue.

    Abstract: The storage unit comprises an array of tunnel tips (13) arranged at tunneling distance from a recording surface (2a) of a storage medium (2) which is capable of permitting digital information to be written or read through variations of the tunneling current. The storage medium (2) is attached to the free end of a piezoceramic bendable tube (3). In operation, the free end of the tube (3) is moved in a circular orbit by repetitive sequential energization of oppositely arranged pairs of 90.degree. phase shifted electrodes (4,6 and 5,7). This tube movement causes each tunnel tip (13) to scan a respective unique associated annular area of the storage medium (2). To address a particular concentric track in a particular annular area, tunneling current is applied to the associated tip (13) via respective electrodes (16,18) while, concurrently, a potential is applied via electrodes (4,6 and 5,7) to tube (3) of a magnitude corresponding to the desired orbital diameter for the tube.

    Abstract: The method involves the steps of moving the magnetic head (8) to within aerodynamic distance from the electrically conductive surface (16) of rotating magnetic recording disk, further positioning of the head (8) until a tunnel current occurs across the gap between the head (8) and surface (16), and maintaining said tunnel current constant by using the deviations of the current from a predetermined value corresponding to a certain flying height.The apparatus comprises a tunnel electrode (9) forming an integral part of the head assembly which is attached to a distance control mechanism (5) permitting the positioning of the head assembly with a one-nanometer accuracy. The tunnel electrode (9) has a very slightly beveled shoulder (45, 47) ensuring early detection of asperities approaching the head. Gradation of the potential between tunnel electrode (9) and surface (16) of the recording disk (3) is used to enhance the response to asperities.

    Abstract: The present invention provides sensors based on micromachined ultrasonic transducer technology. The sensors preferably include a plurality of sensor elements, but may include only one sensor element. Arrays of sensors are also provided. Sensor elements include a functionalized membrane supported over a substrate by a support frame. The functionalized membrane, support frame and substrate together form a vacuum gap. The sensor element is connected to an electrical circuit, which is configured to operate the sensor element at or near an open circuit resonance condition. The mechanical resonance frequency of the functionalized membrane is responsive to binding of an agent to the membrane. Thus, the sensor element also includes a detector, where the detector provides a sensor output responsive to the mechanical resonance frequency of the sensor element.

    Abstract: The invention relates to molecules which can be attached to a substrate (4) and switched between different stable or metastable conformations (18, 19). At least one of these conformations (19) is generated and/or stabilized by the proximity of the substrate (4). The invention further relates to a layered medium comprising such molecules and to a method to switch such molecules in a controlled way. The layered medium is usable as resists for lithographic application, data storage media, and promoter of electron transfer between two media. The method is usable to generate and interrogate patterns in the layered medium.
