トランスデューサ、被検体情報取得装置
Document Type and Number:
Japanese Patent JP5855050
Kind Code:
B2
Abstract:
A transducer includes a plurality of elements each including at least one cell structured in such a way that a diaphragm including one of a first electrode and a second electrode disposed facing each other via a space is vibratably supported, bias wiring for supplying a bias voltage to the first electrode to provide a potential difference between the first and the second electrodes, and for electrically connecting the first electrodes of the elements to each other, and signal wiring lines each connected to a different one of the elements. The bias wiring includes a plurality of branch wiring lines to each of which the first electrodes of a part of the elements are connected, a plurality of first common wiring lines for connecting the branch wiring lines to each other, and a second common wiring line for connecting the first common wiring lines to each other.
