Objective 2: Conduct Experimental Activities on Performance of Sensor‐Equipped Composite Elements
In this report we present the basic principles of our exploratory research for embedding sensors and energy-harvesting devices in sandwich composite structures. A range of piezopolymer sensors where used, varying in their dimensions, their capacitance and the electrode coating material. Sensors were tested in the surface-attached and embedded formats on composite sandwich laminates. Specimens were tested under three-point bending configuration to measure both the sensor voltages and the generated laminate strains. The electromechanical sensitivity performance with respect to frequency and strain amplitude were the key performance parameters investigated. Primary conclusions, of a practical nature, were extracted concerning the appropriate type of sensor for embedding applications as well as the parameters affecting the sensitivity and efficiency of the devices to perform as energy both strain gauges and energy-harvesting devices.
