摘要： A backing includes a plurality of backing plates that are laminated. Each backing plate includes a lead row and a backing material. Each lead includes a lead wire and an insulating coating. The insulating coating is integrated with the backing material, and an adhesive layer between them does not exist. Short-circuit between the leads may be prevented or reduced by the insulating coating. The backing plate is manufactured by a screen printing method.

摘要： Described herein is an additive manufacturing apparatus that is well-suited for constructing piezoelectric sensors. The additive manufacturing apparatus includes an extrusion nozzle formed of a conductive material such as aluminum. The extrusion nozzle has a channel by way of which printing material exits the extrusion nozzle, wherein a build plate is configured to receive the printing material responsive to the printing material exiting the extrusion nozzle. An arc suppressor formed of a semiconductor is coupled to the extrusion nozzle and is configured to dissipate excess charge that would otherwise exist on the extrusion nozzle when a relatively high bias voltage is applied to the extrusion nozzle. Thus, the arc suppressor mitigates arcing between the extrusion nozzle and the build plate. Arc suppressing gas is also optionally introduced into a printing region, thereby further mitigating arcing between the extrusion nozzle and the build plate.
