    • The present invention provides the stress detection method for force sensor device with multiple axis sensor device and force sensor device employing this method, whose installation angle is arbitrary. The stress detection method includes, first and second force sensors whose detection axes are orthogonal to each other. When the detection axis of first force sensor forms angle θ with direction of detected stress Ax, and the stress component of direction perpendicular to direction of the detected stress Ax is Az, output Apx of the axis direction of first force sensor is found as Apx=αx (Ax×cos θ+Az×sin θ), and output Apz of the axis direction of the second force sensor is found as Apz=αz (Ax×sin θ+Az×cos θ), and, when αx and αz are detection sensitivity coefficients of first and second force sensors respectively, the detection sensitivity coefficient αz of second force sensor is set as αz=αx tan θ, and the detected stress Ax is found as Ax=(Apx−Apz)/αx(cos θ−tan θ×sin θ).

    • A method of manufacturing a piezoelectric actuator, formed of multiple concave parts which are provided on one surface. First, a first sheet is formed of pliant piezoelectric materials and a second sheet is formed of pliant predetermined materials, forming an upper electrode layer formed of conduction materials on one surface of said first sheet, and forming a lower electrode layer formed of conduction materials on the other surface of said first sheet or one surface of said second sheet, wherein piezoelectric material is used as said material of the second sheet and electrode layer for polarization formed of conduction material is formed on the other surface side of said second sheet. Next, the first and second sheets are piled and densified. The first sheet is polarized in a direction of a thickness of the first sheet. In a fourth step, the upper electrode layer is patterned in order to form multiple electrodes corresponding respectively to each pressure chamber of the pressure chamber forming unit, wherein by placing a voltage between the upper electrode layer and the electrode layer for polarization, the first sheet is polarized in the direction of its thickness.
