Show affiliationsHigh performance force sensors often encounter the conflicting requirements of fine sensitivity and wide bandwidth. While there is an intrinsic tradeoff between these two metrics that cannot be physically avoided for any force transducer, through proper optimization the product of these two can be maximized. Similarly, the requirements of multiple sensing axes and overall compactness are also often at odds. This paper describes a novel design, simple method of fabrication, and thorough analysis of a high performance two-axis force sensor. We conclude with an example application: measuring the lift and drag forces from a flapping-wing robotic insect.
