The low-cost, widespread availability and robust nature of current electronic devices suggest the feasibility of creating a composite\r\nstructure with integrated networked sensors to monitor in real time the life of civil and aerospace structures while in service\r\nconditions. For structures that need to survive to high number of life cycles under varying load-environmental conditions, it is of\r\ncrucial importance that the strength, stiffness, endurance, and general load-bearing capabilities of the composite not to be severely\r\ndegraded by the integrated networked components. Therefore, design tools must be developed to achieve optimized, safe, and\r\nreliable structures. High values of stress concentrations due to the presence of a rigid device within a highly anisotropic material\r\ncan trigger the initiation of microcracks in the resin matrix. To quantify these effects, the acoustic emission technique is used to\r\ncharacterize the initiation of microfailures within laminated composites with integrated electronics.
