Abstract:
A deformation sensor package includes a housing having a base and a peripheral wall extending from the base. The base and peripheral wall define two cavities each configured to receive a potentiometer, such as a string potentiometer. The peripheral wall defines two apertures formed between a respective cavity and an exterior of the housing. Each aperture is configured to allow for the passage of a moveable sensing end of an associated potentiometer therethrough.
Abstract:
A protector (10) with a sensor (80) is installed on a sliding door (1) for detecting an alien substance by touch between two core wires (31,32) in a hollow part (12). In a terminal part of the protector with the sensor, the core wires drawn out are connected with legs of a resistor (39). A primary seal (100) is formed by grinding a surface of the hollow part (12) of the terminal part of an extrusion molded part, positioning a ground part (51) on a die and covering wire connection parts (70) and a side of another end of an insert while also covering the ground part (51) by means of injection molding. A secondary seal (200) is formed by means of the injection molding for coating a part formed with the primary seal for forming an external shape of a product.
Abstract:
The optical force sensor includes a base member (1), a displaceable member (2), an elastic member (3) disposed between the base and displaceable members and a displacement detector (5) optically detecting a displacement of the displaceable member caused by an external force. The displacement detector causes first and second light fluxes (21, 22) to form interference fringes on a first light-receiving element (7A-7C). The first light flux from a light source (6) is internally reflected at a gap-side surface (9a) of a light-transmissive member (9). The second light flux from the light source is transmitted through the light-transmissive member, reflected by a reflective surface (4a) provided to the displaceable member and again transmitted through the light-transmissive member. The displacement detector outputs, from the first light-receiving element, a signal corresponding to a variation in intensity distribution of the interference fringes.

Abstract:
A magnetic load sensor unit (1) is provided which can detect the magnitude of an axial load applied by a linear motion actuator (14) to a friction pad (22). The magnetic load sensor unit (1) includes a magnetic target (4) which generates a magnetic field, and a magnetic sensor (5) designed to move relative to the magnetic target (4) corresponding to the axial load.
Abstract:
A piezoelectric strain sensor and method thereof for detecting strain, vibration, and/or pressure. The sensor incorporates a sequence of piezoelectric and semiconductor layers in a thin-film transistor structure. The thin-film transistor structure can be configured on a flexible substrate via a low-cost fabrication technique. The piezoelectric layer generates an electric charge resulting in a modulation of a transistor current, which is a measure of external strain. The sensor can be formed as a single gate field-effect piezoelectric sensor and a dual gate field-effect piezoelectric sensor. The semiconductor layer can be configured from a nanowire array resulting in a metal-piezoelectric-nanowire field effect transistor. The single and dual gate field-effect piezoelectric sensor offer increased sensitivity and device control due to the presence of the piezoelectric layer in the transistor structure and low cost manufacturability on large area flexible substrates.
Abstract:
Ein Kraftsensor besitzt ein zylinderförmiges Gehäuse, das durch eine senkrecht zu seiner Mittelachse auf es einwirkende Kraft elastisch verformbar ist. Das Gehäuse weist einen Hohlraum auf. In dem Hohlraum ist eine Messwandleranordnung angeordnet, mit der die Verformung des Gehäuses erfassbar ist. Die Messwandleranordnung weist eine scheibenförmige Trägerplatte auf, auf deren Oberfläche ein Dehnmesswandler befestigt ist. Die Trägerplatte ist so im Hohlraum befestigt, dass sich eine Verformung des Gehäuses auf die TrägerPlatte überträgt.
