| Abstract: | The use of 3D printing has grown exponentially over the last few years. Individuals are able to print their own designs and products. However, the industry has not yet adopted this innovative production method to its full potential. Products are produced in bulk with lots of waste, causing environmental problems. Even with the production of sensors. This project is therefore focused on producing a functional flow sensor that is fully 3D printed. In this project a flow sensor is designed to measure the airflow over the wings and/or body of a robot bird. The foremost requirement of this sensor is that it should be produced in a 3D printer and require as little assembly as possible. Three different models have been designedwhereof one design has been produced. This model has the shape of a flat plate with a strain gauge on the front and a strain gauge on the back of the plate. These strain gauges are made of the PI-ETPU conductive material while the largest part of the sensor consists of Ninjaflex. Both these materials are flexible plastics (TPU) which make the sensor act as a deform-able beam. The produced sensor is able to measure deformations that are equivalent to air flows up to at least 25ms¡1, using the piezoresistive properties of the PI-ETPU filament. |
