TL;DR: In this paper, the effect of damage size on the propagation of Lamb waves is presented, and the technique is applied to a stiffened panel, where damage on the skin or flange is detectable while damage on a web or cap is not detected with the current experimental set up.
Abstract: The aim of the present work is to develop a system of smart devices that could be permanently attached on the surface of the composite structure and monitor the interaction of low-frequency Lamb waves with defects. A linear array of transmitters would generate a relatively uniform wavefront allowing the inspection of large areas with a limited number of sensors. The asymmetric A0 Lamb mode is generated in carbon fibre reinforced plastic (CFRP) quasi-isotropic laminates using an array of thin piezoceramic transmitters operating in-phase. In this paper, the effect of damage size on the propagation of Lamb waves is presented. Experimental verification is also presented in multidirectional CFRP composite panels. Critical size impact damage is detected. Finally, the technique is applied to a stiffened panel. Damage on the skin or flange is detectable while damage on the web or cap is not detected with the current experimental set up.

TL;DR: In this article, a self-contained device for harvesting electrical energy from linear and rotary motion has a sensor with amplifiers for tensile stretching of a piezoelectric body (100) with magnification of the applied force.
Abstract: A self contained device for harvesting electrical energy from linear and rotary motion has a sensor with amplifiers (104, 106) for tensile stretching of a piezoelectric body (100) with magnification of the applied force. The piezoelectric body is a monolithic plate with surface electrodes (120, 122) covering its top and bottom surfaces.

TL;DR: In this article, a novel piezoelectric energy harvesting system using the wake galloping phenomenon is explored for the broad wind spectrum, where the flow of wind runs parallel to the placed cylinders with upstream cylinder fixed at one end while the downstream one is placed over an unimorph cantilever beam with piezolectric film attached to it.
