摘要： Provided is a control apparatus and control method for a capacitive electromechanical transducer with small decrease in transmission/reception efficiency, and with sets of transmission/reception characteristics with different frequency ranges. The apparatus has cells each including first and second electrodes facing each other via a gap; includes a driving/detecting unit and an external stress applying unit. The driving/detecting unit performs at least one of causing the second electrode to vibrate and transmit elastic waves by generating an AC electrostatic attractive force between the electrodes, and detecting a change of capacity between the electrodes, the change being caused by the second electrode vibrating upon receipt of elastic waves. The external stress applying unit changes the external stress applied to the second electrode. The driving/detecting unit adjusts frequency characteristics by changing a parameter defining the frequency domain used in a transmitting/receiving operation, corresponding to the change of the external stress.

摘要： An angular velocity sensor includes a supporting substrate, a detecting portion, a displacement detecting portion, a first driving portion, and a second driving portion. The detecting portion is supported by the supporting substrate movably in at least a free direction. The displacement detecting portion detects a displacement of the detecting portion in the free direction. The first driving portion excites a first reference oscillation of at least a portion of the detecting portion so that a first Coriolis' force in the free direction is generated in response to an angular velocity about a first axis. The second driving portion excites a second reference oscillation of at least a portion of the detecting portion so that a second Coriolis' force in the free direction is generated in response to an angular velocity about a second axis.
