Summary: Flexible pressure sensors are becoming increasingly important in various applications such as human health monitoring, soft robotics, and human-machine interfaces. A conventional approach to achieving high sensitivity is by introducing microstructures to engineer the sensor's internal geometry. However, this strategy results in a thicker sensor which impairs conformability on surfaces with microscale roughness. In this manuscript, a nanoengineering strategy is introduced to resolve the conflicts between sensitivity and conformability, resulting in the thinnest resistive pressure sensor with superior sensitivity and conformability.
