The application provides a non-invasive implantable wall deformation volume sensor, and relates to the technical field of implantable biomedical sensors, which comprises an elastically deformable closed ring-shaped base, a conductive coil arranged on the ring-shaped base, a capacitor forming an LC resonant circuit with the conductive coil, an elastic support structure arranged in the ring-shaped base, and a biocompatible encapsulation layer covering the outside. The sensor controls the distribution ratio and mechanical rigidity of the support structure, so that the ring-shaped base produces controllable concave deformation under the action of the pressure of the inner wall of an organ, thereby changing the geometric parameters of the conductive coil and causing the resonant frequency to change, and the detection of the volume change of the organ is realized. In addition, the elastic support structure and the ring-shaped base form a connection mode allowing relative sliding, so that the sensor can automatically expand by the elastic force after compression delivery. The application can respond to the overall geometric deformation, and has the advantages of simple structure and high mechanical compliance.
