Estudo sobre modelos de estruturas tridimensionais para impressão 3D aplicadas no desenvolvimento de piezoeletretos

Abstract

Every day technology advances in a way never seen before. With it, the need arises to capture the analog signals coming from the physical environment around us. Today, we measure almost everything imaginable through sensors. Sensors are devices that interpret signals from the world as input and emit a signal as output. There are several types of sensors that can be applied in di erent contexts, but most of them share costly materials and manufacturing processes. The physical structure of the sensor plays a very important role in the way it responds to environmental stimuli. In this work, a study was made on the types of materials that are most suitable for sensor manufacturing technology through 3D printing. The results were obtained with polymeric materials using the piezoelectricity concept. A piezoelectric sensor is a device that measures pressure or stress measurements by deformation of the material producing an electrical signal in response. This type of sensor has several applications. It is widely used in the construction of microphones, sonars, touch screens, biomedicine and scienti c research for new applications. With this, it was possible to develop printed lms using an innovative manufacturing methodology through 3D printing. The lms produced through this technique were tested and it was observed that the material maintained electrical charges stored for a short period of time proving that the material and methodology used is feasible for the production of piezoelectric sensors.
