Abstract: Aspects of the present disclosure are directed to pressure sensing. As may be implemented in accordance with one or more embodiments, an external energy field is applied to a resonant circuit having inductive conductors separated by a compressible dielectric, for wirelessly detecting pressure. Specifically, the resonant circuit is responsive to the energy field and applied pressures by operating in respective states exhibiting different resonant frequencies that are based upon pressure-related compression of the compressible dielectric. These resonant frequencies, or a change in the resonant frequencies, can be used as an indication of the pressure.

Abstract: A sensor that detects contact using compression of a compliant material sandwiched between an electromagnetic signal transmitter and a corresponding signal receiver. Potential applications include inexpensive, robust collision sensors integrated into mobile robot bumpers, and sensors on robot grippers to detect grasping of an object. Deformation of the compliant material in response to contact forces changes the distance between the transmitter and the receiver, affecting the electromagnetic field between them. Changes in this electromagnetic field provide information on the location and magnitude of the contact forces. A transmitter and receiver may form opposing surfaces of a capacitor; the measured capacitance changes as the distance between transmitter and receiver changes. Alternatively, the strength of a received signal may be monitored to detect changing distance between transmitter and receiver. Shielding and signal filtering may be used to mitigate the effects of electromagnetic noise.

Abstract: A plurality of core bodies are housed within a casing having an opening portion on one end side. A core body selecting mechanism is provided which includes a plurality of operating portions coupled to each of the plurality of core bodies, and makes at least a tip of one core body among the plurality of core bodies selectively project from the opening portion of the casing. A pen pressure detecting portion common to the plurality of core bodies is provided within the casing. When the operating portion is operated to make at least the tip of the one core body project from the opening portion, part of the operated operating portion engages with the pen pressure detecting portion common to the plurality of core bodies, and the pen pressure detecting portion detects a pen pressure applied to the tip projected from the opening portion.

Abstract: A position indicator includes a capacitor having a capacitance that changes in correspondence to a force applied to one end part of a housing. The capacitor is configured by a pressure detecting chip that includes a first electrode and a second electrode disposed opposite to the first electrode with a predetermined distance defined therebetween to have capacitance Cv formed between the first electrode and the second electrode. The capacitance Cv changes when the force applied to the one end part of the housing is transmitted to the first electrode to thereby change a relationship (e.g., the distance) between the two electrodes. A pressure transmitting member having predetermined elasticity is disposed on the first electrode such that the force applied to the one end part of the housing is transmitted to the first electrode of the semiconductor element via the pressure transmitting member.

Abstract: A pressure sensor measures pressure by measuring the deflection of a MEMS membrane using a capacitive read-out method. There are two ways to implement the invention. One involves the use of an integrated Pirani sensor and the other involves the use of an integrated resonator, to function as a reference pressure sensor, for measuring an internal cavity pressure.

Abstract: A capacitive sensor for detecting the movement of an object, such as actuation of a key of an operating unit, includes first and second electrodes that are provided for connection or mechanical coupling to or arrangement on the object, the distance of which second electrode from the first electrode changes when the object moves. The electrodes form a first capacitor with a volume between the electrodes, the size of which changes when the object moves. An evaluation unit determines a change of capacitance between the two electrodes resulting from a change of their spacing and volume. A deformable, non-gaseous first dielectric is arranged between the electrodes and defines at least one gas volume that is filled by a gaseous second dielectric that can escape from the gas volume when the two electrodes approach one another.

Abstract: An electronic device includes a frame to be worn by a user, at least one strain gauge coupled to the frame, and a control unit. The at least one strain gauge generates a deformation measurement signal indicative of an amount of strain caused by deformation of the frame. The control unit identifies the user wearing the frame based on the deformation measurement signal.
