“…In robotics, angle sensors play a vital role in monitoring robot joint motion and ensuring precise positioning of robotic arms and other components, resulting in increased productivity and efficiency. Therefore, the development of high-precision and reliable angle sensors has become crucial to ensure the accuracy and effectiveness of these systems. , Angle sensors based on laser, electrical, and magnetic principles have been developed, which offer a large measuring range and high precision. − However, it is worth noting that these sensors tend to be both expensive and large in size. , Given the trend toward miniaturization, there is a pressing need to develop angle sensors that can be easily manufactured at a low production cost.…”

Liquid metal (LM) as the universal artificial biomimetic sensory material has attracted much interest in academic and industrial applications, such as soft robots, flexible electronics, and micro−nano devices. It remains a pivotal challenge to develop a stable and highly sensitive angle detection with a rapid response. Herein, we present an LM-based angle detection sensor. Ga-based LM is gradually injected into hollow fibers with rough internal structures, resulting in a gradient of LM content inside the fibers due to the synergistic effect of pressure drop and the fast formation of an oxide film on its surface. The LM is affected by the gravity pressure when the fiber is tilted, and the Laplace pressure on the surface of the LM continuously reaches an equilibrium state to induce the continuous deformation of the LM. The proposed sensor with highly sensitive to the tilt angle and showcases a linear relation with the tilt angle. For its advantages, this work shows a great potential application in sensor fields and opens routes for the application of electronic whiskers.

“…A straightforward approach to achieving the multi-dimensional angle sensor uses two or more sets of 1-D angle sensors, but this approach is straightforward and increases the system cost and complexity. A few works have been reported for 2-D angle sensor [30][31][32]. As far as we know, no two-dimensional angle sensor based on optical fiber has been reported so far with a maximum measuring range of 360º.…”

The developed angle sensors are usually used for either clockwise or an anti-clockwise direction. Here, we present a relatively new setup of two angle sensors (1-D and 2-D) for independent and simultaneous clock and anti-clockwise rotation measurements. The proposed sensor is based on the twisted macro-bend coupling method (TMBC), in which two fibers are twisted and bent. The two-angle sensors are presented in which sensor-1 consists of a single twisted bend and sensor-2 contain two twisted bends on a single transmitting fiber. The angle measurement relies on the coupling of macro-bend loss. The stepper motor is used to drag the twisted fiber, resulting in a change in the bending radius that increases or decreases the macro-bend loss. A novel cascading method is introduced in the TMBC method for the sensor-2 and, two stepper motors are used in the second experiment. To prove the practicality, several test scenarios are conducted for both sensor configurations. The experimental results show that sensor-1 can measure angle ±180º, whereas the full clock and anti-clockwise cycle are achieved through sensor-2, having a measurement range is ±360º. Therefore, the proposed sensor can be a potential means for accurate angle measurement in industrial applications.

“…All-fiber sensing merits are well known to be small, to transmit over long distance, to be immune to Electro Magnetic Interference (EMI), which are also especially suitable for tilt sensing applications. The previously proposed optical fiber tilt sensors were almost based on fiber Bragg grating [1][2][3][4][5][6]. In those references, the tilt angle were determined by demodulating shifts of the fiber Bragg grating (FBG) center wavelength when the tilt angle changed.…”

A highly sensitive tilt angle sensor based on an all-photonic crystal fiber interferometer (All-PCFI) was proposed and demonstrated in this paper. The All-PCFI was formed by a PCF with two collapse regions that were fabricated by fusion discharge technique. Then a device formed by cantilever beams and iron ball was designed to transform the tilt angle to the strain, which would be detected by measuring the spectral responses of the All-PCFI. Experimental results showed that the spectrum would be red-shifted when the tilt angle changed from 0deg to 90deg.And in the measurement range of 0deg~45deg, the linear measurement sensitivity could be up to 55.67pm/deg. In addition, the sensor could measure the tilt angle in all directions by demodulating signals of the four cantilever beams.
