Abstract: PURPOSE: A sensor used for a pressure sensor, a flow sensor, an actuator accelerometer or the like is provided to be capable of testing periodically or continuously. CONSTITUTION: In order to provide a linear response in this example the parameter sensing signal is central around the 1 x 104 Hz range. As will be described below with reference to figure 6, the device of the invention has a varying response to excitation frequency, with several peaks. As mentioned above, in this example a sensing signal frequency is generally located in this case in the region of 1 x 104 Hz. This enables the device to be excited at a resonant frequency for example in the region of 1 x 105 Hz without effecting the sensing signal, but in a manner which is employed to determine the functionality of the device either on a continuous or intermittent basis.

Abstract: Aspects of the subject disclosure include a pressure-sensing device consisting of a housing including a membrane and one or more piezoresistive elements disposed on the membrane to sense a displacement due to a deflection of the membrane. A first set of electrodes is disposed over the membrane, and a second set of electrodes is disposed on a permeable port of the device at a distance from the membrane. The first and second sets of electrodes form an electrostatic actuator to exert a repulsive force onto the membrane to reduce the deflection of the membrane.

Abstract: A physical quantity sensor includes a deformable body in which strain occurs in response to a stress applied thereto, a vibrator vibrating with a frequency according to the strain or with an amplitude according to the strain, and a processor processing a signal output from the vibrator. The vibrator is mounted to the deformable body such that the strain transmits to the vibrator. The processor is bonded to the deformable body such that the strain does not substantially transmit to the processor. This physical quantity sensor can stably detects strain and tension acting on an object.

Abstract: A sensor formed from a semiconductor material. The device comprises a support frame, a sensing element; and means for vibrating the sensing element at a frequency corresponding generally to a first resonant frequency vibration mode. Error detection means detects the resonant frequency vibration mode, the output of the error detection means being indicative of existence or otherwise an expected response of the resonant frequency vibration mode to the excitation. Means for detecting the deformation of the sensing element provides an output indicative of the parameter to be sensed, the deformation detecting means and error detection means being formed from the same elements.
