A stretchable capacitance sensor having multiple components for communicating signals to a data acquisition system for reconstructing an image of an area or object located in a subject being sensed, and for calculating the shape or conformity that it is in. The stretchable sensor consists of an inner layer of plates that provide the capacitance data, a middle layer of plates that provide the geometry-sensing data, and an outer layer of plates that serves as the shielding ground layer. The configuration of all three components can be variably changed to increase the capacitance data channels, increase or decrease flexibility and stretchability of the sensor, and increase the spatial resolution of the geometry sensing feature. The sensor is adapted to communicate signals to a data acquisition system for providing an image of the area or object between the capacitance plates.
