Abstract: A novel sensor, intended for use in applications for robots, prosthetics, biomedical devices, or the internet of things, using a ferrous magnetic fluid is presented here. The sensor includes a deformable member containing the magnetic fluid therein and an array of Hall effect sensors to measure the changing magnetic field in the fluid as the deformable member is deformed. The sensor was found to be sensitive to varying applied pressure and is capable of resolving both the location and amplitude of externally applied forces. The range of applications for this novel pressure sensor are broad, ranging from robotics to biomedical devices and the Internet of things. The novel sensor can also be used as an orientation sensor or an accelerometer, torque detector and linear shear forces detector.

Abstract: A touch panel device includes a face plate, a bracket, and a PCB. The face plate receives a contact. The bracket includes a permanent magnet affixed to a surface of the bracket. The PCB is positioned proximate to the bracket such that a surface of the PCB is adjacent to the bracket. The PCB includes a Hall sensor collocated proximate to the permanent magnet. The touch panel circuit is coupled to the Hall sensor. When the contact is received at the face plate, the PCB moves closer to the bracket. In response, the touch panel circuit receives a voltage from the Hall sensor, determines a force associated with the contact based upon the voltage, and triggers a haptic feedback response in the bracket.

Abstract: A force sensor is suitable for an electrohydraulic hitch control system of an agricultural tractor. The force sensor has an outer cylindrical part with a bore and a measuring rod fixed on one side in the bore. A central section of the cylindrical part is provided as force introduction section. Two outer sections of the cylinder part are removed equally far axially from the center of the force introduction section and are provided as abutment sections. The measuring rod is clamped in an area of the force introduction section.

Abstract: A robotic sensing and touch apparatus detects gradual deformations in a resilient surface, in contrast to conventional rigid member displacement. Hall effect sensors coupled to rare-earth magnets in a deformable base allow sensing of surface curvature and compression against grasped objects. The deformable base, such as a silicone mold or other resilient encapsulation, fixes a magnetic source and an opposed Hall effect sensor. Calibration of a received magnetic field is defined by a sensor element voltage in an “at rest” (undeformed) state, and at successive degrees of deformation resulting from compression of the deformable base that draws the magnet in different orientations relative to the Hall effect sensor. An array of magnet and sensor element pairs allows relative sensing over an area for detecting curvature of a translated or articulated member, or engagement with a curved surface.

Abstract: The present invention provides a sensor having an improved sensitivity and precision, which is lighter and more flexible than conventional sensors, and a method of making the sensor. The present invention relates to a sensor comprising a resin foam containing a magnetic filler, and a magnetic sensor that detects a magnetic change caused by a deformation of the resin foam, wherein the resin foam is a polyurethane resin foam that comprises a polyisocyanate component, an active hydrogen component, a catalyst and a foam stabilizer, and wherein the resin foam has a hardness change (H1-H60) of 0 to 10 between a JIS-C hardness (H1) in one second after contact with a pressure surface of a hardness tester and a JIS-C hardness (H60) in 60 seconds after the contact.

Abstract: A magnetic load sensor is provided which is high in axial rigidity. The load sensor includes a pair of parallel plate coupled together by coupling pieces. The coupling pieces are inclined relative to the axial direction such that when an axial load is applied to the parallel plates, the parallel plates are displaced relative to each other in a direction perpendicular to the axial direction, due to deflection of the coupling pieces. A magnetic target is mounted to the parallel plate, and a magnetic sensor element is mounted to the parallel plate such that when the parallel plates are displaced relative to each other in the direction perpendicular to the axial direction, the magnetic target and the magnetic sensor element are displaced relative to each other in the direction perpendicular to the axial direction.
