Abstract: A force sensor includes first and second layers formed from an electrically conductive material. The force sensor further includes a third layer formed from a piezoresistive material disposed between the first and second layers. The force sensor can be incorporated into a device, e.g., a pushbutton type of device, that emits a signal in proportional response to a force being applied to the sensor, e.g., pushing the button.

Abstract: A stress sensor includes a semiconductor substrate with a first transistor arrangement and a second transistor arrangement. The first transistor arrangement includes a first transistor with a first source-drain channel region and a second transistor with a second source-drain channel region. The first transistor and the second transistor are aligned relative to each other such that the current flow directions in the first and the second source-drain channel regions are opposite to each other. The second transistor arrangement includes a third transistor with a third source-drain channel region and a fourth transistor with a fourth source-drain channel region. The third transistor and the fourth transistor are aligned relative to each other such that the current flow directions in the third and the fourth source-drain channel regions are opposite to each other. The stress sensor generates a gradient-compensated output signal used to determine a mechanical stress acting on the semiconductor substrate.

Abstract: A mask fitting level determination device includes a mask inner pressure detection unit inserted between a mask covering a mouth, nose and a face surface of a person to measure a pressure inside the mask. A circuit control unit derives information of a pressure value measured by the mask inner pressure detection unit and generates display information for the person wearing the mask. A determination display unit shows the person the display information generated by the circuit control unit. A battery unit supplies electricity to the circuit control unit and the determination display unit. A power supply switch starts and stops the supply of the electricity to the circuit control unit and the determination display unit. A start switch starts the mask inner pressure detection operation.

Abstract: Apparatus and associated methods relate to sensing a physical parameter and verifying correct operation of a system used to sense the physical parameter. A sensing device includes four resistive elements configured in a Wheatstone bridge configuration is configured to sense the physical parameter. A biasing network selectively provides first and second biasing conditions to the sensing device. First and second output electrical signals are generated by the sensing device in response to the first and second biasing conditions, respectively, selectively provided to the sensing device. The first and second output electrical signals are each indicative of the parameter value of the physical parameter, but not necessarily equal to one another. A verification module verifies correct operation of the system based on a consistency determination of first and second output electrical signals.
