<p>A sensor assembly includes a elongate article (13) and a plurality of elongate piezoelectric elements (47, 48) provided to the elongate article. Each of the piezoelectric elements is configured so that when a load is applied in a direction perpendicular to a surface of the piezoelectric element, a short axis (XS) direction of the piezoelectric element becomes a sensitivity direction in which a voltage is generated, and a major axis (XL) direction becomes a non-sensitivity direction in which a voltage is not generated.</p> |
