Here, an innovative noncontact interactive visualized sensor based on an electret is reported. Visualization of a floating external object, such as the contour, the separation distance and the velocity, is achieved in a completely non-contact way. Besides, identification of hidden patterns inside the device, including letters and a bar code, is successfully acquired through a non-contact scanning method.
