AI Technical Summary
Existing flexible pressure sensors present a trade-off between sensitivity, detection limit, thickness, and detection range, making it difficult to improve sensitivity and expand the detection range while maintaining thinness and lightness.
The design employs an interdigitated electrode layer, including a first electrode layer and a second electrode layer. The specific shape and arrangement of the interdigitated fingers in the interdigitated electrode layer increase the effective contact area. Combined with a pressure-sensitive layer and an annular insulating layer, stress concentration is avoided. The design uses a planar design and polymer-free materials to adapt to complex shapes and curved surfaces.
The sensitivity and detection range of the flexible pressure sensor have been improved, its mechanical stability and service life have been enhanced, response time delay has been avoided, it is suitable for force detection of flexible non-planar objects, and the accuracy of the detection signal has been improved.
