The project aim is to evaluate if vibrations, in a train bridge, can be used in an on-demand bridgemonitoring system, for vibrational stress, using a technique called EcoSense. The EcoSense architectureis used to reduce the power consumption of sensors by only allowing them to use power when a desiredmeasurement is wanted (e.g. a train passes). The main task is to analyse how such a system can bebuilt to perform as efficiently as possible. The system should be tested at Lidingö bridge in Stockholm.The resulting circuit was successful to be used as an on-demand switch for a sensor on Lidingö bridge.Testing and evaluation of different specifications of the circuit was done. The final conclusion is thatEcoSense is applicable for bridge vibrational sensing and designs can be tailored to fit the specificationsof a bridge.
