Abstract | This work presents 3D printed tilt sensor to measure fluid level and tilt sensing in robotics. It comprises of four 3D printed interdigitated capacitive sensors printed as a single structure and immersed in liquid EcoflexTM (part A only). When the orientation of the sensor changes, the level of fluid in contact with the sensors also changes and this causes a change in the capacitance. The sensors were first printed individually and change in capacitance measured for different fluid levels. The response of the individual capacitive sensors shows a stable response for a dip and remove cyclic test in fluid at frequency of 0.625Hz. The results of the tilting experiments show a relative change in capacitance (ΔC/C 0 ~0.1% per degree for an angle range of ~ -20° to ~+20°. With ~6.7° detected per mm of the level of fluid in contact with the sensor, the result shows the capability to achieve a measurement range of at least ~±93.8° (for a sensor of length of ~12mm). The study carried out in this work finds application in tilt sensing in robotics as well as in fluid-level sensing in which case the sensor could be printed as part of the structure of the fluid container. |
