Patent number: 8513859Abstract: An interactive panel including a substrate, wherein a seismic wave is intended to propagate, and at least two piezoelectric transduction devices each including two piezoelectric transducers. Each piezoelectric transducer includes two piezoelectric elements each with two surfaces each covered by an electrode. The four electrodes of each piezoelectric transducer are interconnected to supply, when opposing stresses are applied to the piezoelectric elements of the transducer, an electrical measurement signal that depends on the angle between a main plane and an opposite stress-separation plane. Two piezoelectric transducers of a same device have a same central axis and their respective main planes form a non-zero angle thereinbetween. Each piezoelectric transduction device is attached to the substrate such that movement of the substrate during passage of the seismic wave causes stress on the piezoelectric elements, in opposite directions on either side of the stress-separation plane.Type: GrantFiled: February 1, 2011Date of Patent: August 20, 2013Assignee: Commissariat a l'energie atomique et aux energies alternativesInventor: Jean-Pierre Nikolovski
