摘要： A double beam extensometer, for use in a tensile- or creeptesting machine, particularly well suited for accurately and directly measuring the gauge length strain of thin material specimen, including composites and filaments as thin as 0.001 inch to a temperature of 5,000* F. in a high vacuum. The extensometer includes a brass lower body that contains two linear variable differential transformer windings, a copper upper body to which is affixed a closed end austenitic stainless-steel tube which extends downwardly through the linear variable differential transformer windings, a copper beam support bracket that clamps to the upper body, and cores, core suspensions, beams, extension strips, and associated conventional components, such as power supply, control panel with oscillator-demodulator and recorder readout. As the specimen is strained by the applied load, the beams are displaced and cause differential movement of the cores in the linear variable differential transformers and, therefore, difference in voltage as to each linear variable differential transformer. The difference in voltage is then read directly as the gauge length strain undergone by the specimen.

摘要： An electromechanical sensor and a method of sensing an object or a tactile input using the sensor. The sensor includes: a base provided with a magnetic sensor arranged to detect a change in magnetic flux at the position of the magnetic sensor; a flexible film adjacent to the magnetic sensor; and a magnetic element provided on the flexible film; wherein the magnetic element is arranged to move relative to the magnetic sensor when the flexible film is reversibly deformed by an external force applied to the flexible film.

摘要： A soft magnetic sensor comprising a soft material containing randomly distributed magnetic microparticles and a magnetometer that can estimate force and localize contact over a continuous area. A reference magnetometer can be used to filter motion and ambient noise. Methods for locating contact and determining force comprise data analysis of the magnetometer output. In some embodiments, the sensor can localize an object prior to contact.

摘要： The present disclosure discloses a magnetic flexible tactile sensor structure based on a folding magnetization method, which comprises a flexible body containing a permanent magnetic material; the flexible body has a negative Poisson's ratio structure, and its set area has undergone folding magnetization treatment. The present disclosure also discloses a sensor composed of the above-mentioned sensing structure. The sensor provided by the present disclosure can be applied in sealed and wireless scenarios. The present disclosure can detect the size and position of force. The flexible sensor has broad prospects in the application of the touch skin of robots. The function between the magnetic field-based sensing magnet and the Hall element is contactless. In some cases where it is difficult to establish isolation of the connection lines, it can also be used as an unfettered tactile sensor.
