A laminate material 10 comprises an array of sensors on a stretchable sensor layer 12 and a plurality of elongate actuators on an actuation layer 14. The actuators deform the laminate material 10 by measurements taken from the sensors. The actuators may comprise piezoelectric fibres and may be controlled by interdigitated electrodes on the actuation layer 14. The laminate material may comprise a plurality of actuation layers wherein a given layer’s actuators are angularly offset from another layer’s actuators. The laminate material 10 may comprise a host material 16 (e.g. a fibre, carbon or lattice structure composite). The sensors may measure temperature, pressure or in-plane strain and may comprise bidirectional pressure sensors. The laminate material 10 may be incorporated into an aircraft. Also provided is a method of deforming a layered material comprising a layer 14 of computer-controlled piezoelectric actuators to deform the material based on measurements from a stretchable sensor layer 12.
