Fiber crossbars are an emerging architecture in electronic devices, and they have become the favored fundamental units for state‐of‐the‐art smart textiles. Fiber crossbar sensors with high linearity can provide more realistic pressure feedback, faster circuit response time, and simpler data processing systems. However, due to the unique crossbar structure, replicating existing linear response strategies presents challenges. To address this issue, a fiber crossbar sensor is prepared that incorporates a low modulus coupling circuit (LCFS). The hollow conductive network significantly reduces the sensor's electrode modulus, thereby enhancing its initial sensitivity. The coupling of the parallel and series circuits within the fiber crossbar maintains a linear increase in capacitance. As a result, propelled by the low modulus coupling circuit, the LCFS achieves a highly sensitive linear response. This strategy, independent of intricate microstructures in dielectric layers, has significant implications for fiber crossbar sensor design. Experimental tests and theoretical analyses confirm the effectiveness of this linear response strategy. Because of its high sensitivity and linearity, the LCFS consistently generates reliable and discernible pulse signals, unaffected by pre‐pressures. This empowers the LCFS to recognize various pulse patterns in Chinese medicine, heralding promising applications in daily health monitoring.
