STRAIN SENSOR SWITCH FOR TIMING BASED SENSING
This abstract first appeared for US patent application 20240400375 titled 'STRAIN SENSOR SWITCH FOR TIMING BASED SENSING
Original Abstract Submitted
a strain sensor utilizes an ohmic-based contact switch to detect strain. the sensor can be incorporated into other structures, such as an artificial flapping wing, to detect strain and other parameters, including air flow disturbances. the sensors are fabricated using an additive manufacturing process, with a layer of gold or other conductive material applied for electrical conductivity and uv laser ablation for electrical isolation. the sensor design incorporates mechanical amplification, converting small strains into larger displacements that close contact pads, resulting in an ohmic switch activated at a specific strain threshold. unlike traditional sensors, the switch provides a high or low state output directly without the need for additional amplification or post-processing. the device can detect disturbances in flapping wing cycles and obtain yaw rotation information, with potential applications in other aircraft for disturbance detection.
