Movable items and wearable items worn by users of the same, and systems and methods for monitoring or controlling operation of movable items

摘要

A fiber composite structure contains a circuit and something for sensing a parameter. The structure comprises a plurality of layers. The layers comprise fibrous material impregnated with resin. The resin contains graphene. The preferred fabric layers comprise woven carbon fibres impregnated with epoxy resin containing > 5% and < 2% graphene in different areas. The preferred structure includes adaptive elements which change configuration depending upon a control input, antenna and circuitry. Preferred sensors are pressure or strain gauges, motion sensor, accelerometer, thermocouple, piezoelectric humidity sensor, gyroscope (measuring yaw, pitch and roll), anemometer and radio frequency identity sensor. The structure is used in a bicycle, car, motorbike, train, aeroplane, wheelchair or walking frame.
