Abstract: The invention applies to the technical field of the flexible conductive film and provides a stretchable and super-sensitive flexible conductive film based on silver powder and PDMS and its manufacturing method. The manufacturing method comprises the following steps: preparing silver powder, PDMS prepolymer, and the said PDMS curing agent; after the said silver powder is ground, cleaned, and dried, adding the said PDMS prepolymer for even mixing, and then adding the said PDMS curing agent for mixing to get the liquid flexible conductive film; spin-coating the said liquid flexible conductive film to a certain thickness and get the flexible conductive film after curing. The flexible conductive film comprises silver powder and PDMS film substrate, wherein the said powder silver is evenly distributed within the said PDMS film substrate. The invention provides a flexible conductive film based on silver powder and PDMS and its manufacturing method, whose manufacturing processes are simple and free of hazardous chemical reagents, raising lower requirements for the device but performing well in conductivity and stretchability.

Abstract: An ultrasound probe calibration system and method. The system comprises an ultrasound probe calibration phantom (100), and the ultrasound probe calibration phantom (100) is provided with a sunken recess (110) at a middle position of an upper surface thereof and with several conical holes on a side surface thereof. The sunken recess (110) is fixedly connected with a two dimensional ultrasound probe (220) therein. The conical hole is inserted with an NDI insertion stylus (230), and a tip of the NDI insertion stylus (230) can be acquired in ultrasound imaging. An ultrasound probe calibration system employing the above structure enables a midplane of an ultrasound plane to pass a midplane of an ultrasound probe calibration phantom (100) along a middle gap, such that a tip of an NDI insertion stylus (230) is used for the midplane of the ultrasound plane, thereby addressing the problem of misalignment of a point-type phantom or a two-dimensional plane-type phantom to the ultrasound plane.
