چکیده
Flexible strain sensors are critical to several potential intelligent applications, such as human-machine interfaces, soft robotics, human motion detection, and safety monitoring of components. Stretchable functional materials important components sensors, they still major challenges for high performance sensors. Herein, we demonstrate a novel strategy designing optimizing flexible sensor by developing topological structure modulated permittivity elastic nanocomposite. The with three-phase percolative nano-nanonetworks produces synergistic effects space charge enhancement local electric field modulation, it gives rise an ultrahigh dielectric (113.4, at 1 kHz, over 1500% than that commercial polyurethane matrix) excellent comprehensive electromechanical performance, the optimal reaches 542.91 MPa-1, which is 9-fold film. An interdigital capacitive designed using structured It possesses initial capacitance density positive response stain, achieving signal-to-noise ratio, sensitivity, wide linear range, breaks through disadvantages negative sensitivity narrow range conventional prepared integrated arrays able measure convoluted surfaces monitor actuators in real time, would make conditions control systems study morphological intelligence.

متن کاملHighly Sensitive Fiber Optic Curvature Sensor
A curvature fiber optic sensor using a two-core fiber (TCF) is proposed and demonstrated. The TCF, which is designed to allow coupling between the cores, acts as a directional coupler and thus offers sinusoidal spectral response. The sensor is fabricated by splicing a 50 mm-long section of TCF between two SMFs. When the fiber is bent, the coupling coefficient between the cores is modified mainl...
