“…In addition, athletes’ palms need to remain in a square shape before entering the water. Recent studies show that most wearable sensors can only bend in the longitudinal axis [ 14 , 15 ]. It is necessary to improve the flexibility and stretchability of these sensors for twist motions.…”

Transparent stretchable wearable hybrid nano-generators present great opportunities in motion sensing, motion monitoring, and human-computer interaction. Herein, we report a piezoelectric-triboelectric sport sensor (PTSS) which is composed of TENG, PENG, and a flexible transparent stretchable self-healing hydrogel electrode. The piezoelectric effect and the triboelectric effect are coupled by a contact separation mode. According to this effect, the PTSS shows a wide monitoring range. It can be used to monitor human multi-dimensional motions such as bend, twist, and rotate motions, including the screw pull motion of table tennis and the 301C skill of diving. In addition, the flexible transparent stretchable self-healing hydrogel is used as the electrode, which can meet most of the motion and sensing requirements and presents the characteristics of high flexibility, high transparency, high stretchability, and self-healing behavior. The whole sensing system can transmit signals through Bluetooth devices. The flexible, transparent, and stretchable wearable hybrid nanogenerator can be used as a wearable motion monitoring sensor, which provides a new strategy for the sports field, motion monitoring, and human-computer interaction.

“…Among the EM waveguide designs, optical fibers represent a highly attractive platform for developing contortion sensors, owing to a variety of available design parameters and configurations, a shielded transport of EM radiation, and an opportunity for ultralong length distributed sensing operation. [27][28][29] The optical-fiber contortion sensors may employ gratings, [29][30][31][32][33][34][35][36][37][38][39] modal interference, [40][41][42][43][44][45] radiationlosses, [46][47][48][49][50][51][52] or nonlinear effects to detect and measure the probed contortions. 10,26,53,54 In the past, optical fiber sensors for a distributed measurement of such parameters as temperature, pressure, strain, etc., have been extensively studied.…”

“…The measurement of a bend radius and curvature as well as shape and position using optical fiber sensors has also been demonstrated previously. [29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47]53 While fiber shape sensing is comparable to our application, it is typically applied to systems in which a fiber experiences macro bends and displacements on a length scale greater than a few millimeters. Moreover, while sensors based on fiber microbends have been demonstrated, 55 these typically rely on the overall transmitted intensity or spectrum measured through a fiber core.…”

Continuous measurement of small length scale contortions along an arbitrary path is a highly relevant goal within many branches of engineering and technology. An optical fiber-where the probing light propagates within a confined and shielded region-presents an ideal platform for developing the distributed contortion-sensors. In the past, significant progress has been made in developing optical fiber sensors, but a robust and high-resolution distributed contortion-sensor has not been reported in detail. Here, we report the first distributed measurements of fiber contortions with an ultrahigh sensitivity-≤0.3 µm in the transverse plane, 40 µm longitudinal spatial step size, and ≤8 µm resolution for periodic contortions in the longitudinal plane-via a Bragg-grating-inscribed twisted multicore optical fiber. The results are in excellent agreement with the predictions from the Euler-Bernoulli beam-bending model that relates the applied force with the fiber microcontortions. Our distributed-sensor holds promise for a widespread application within a diverse range of fields including biotechnology, robotics, transportation, geology, and security.
