Purpose and goal
Sensor and actuator integration into the vehicle structure has been identified by the industry as an enabler for future energy-efficient vehicles. This project was performed by Creo Dynamics AB, Elitkomposit AB and Yovinn AB within the "Vinn Excellence 2003" program. The goal of this project was to examine manufacturing processes for the integration of piezoelectric and piezo-resistive sensors in carbon fibre reinforced composite materials and to develop demonstrators that illustrate possible applications of the technology. This goal was successfully achieved.
Expected results and effects
An innovative process for manufacturing of an electrical interface between the built-in sensor and control system has been developed. A special connector was designed for integration in uncured composite materials. This interface was implemented in three demonstrators: a network of strain gauges of embedded thin konstantan wire network for weight localization in a "smart floor", piezoelectric sensors for detection of vibration in vehicle panel, piezoelectric actuators in structural panels for sound generation and a smart panel for active control of sound transmission.
Planned approach and implementation
Project´s structure and goals defined by the participating SME, and was examined by the ECO2 CCGn. Project execution and follow-up under the CCG meetings and workshop was an important reconciliation point for SME partners. The project led to a greater knowledge of all three SME in sensor integration. Demonstrators now play an important role in the parties ´ communication with their respective markets to discuss potential industrial applications of the technology.
