“…Despite the availability of robust and accurate force measurement methods and modalities for robotic systems as shown in a previous study, 54 many of these methods are not applicable to flexible endoscopes. Jin et al 55 introduced a novel vision-based tactile sensing for endoscopy, where a shape memory alloy probe is mounted on the distal tip of the endoscope. The probe is marked at two points, the distance between which changes when an external force is exerted on the probe.…”

Tactile sensors are widely used in the electronic industry. In the following research work, we proposed a tactile sensor based on indium zinc oxide (IZO) electrodes and used neutrosophic statistics to analyze the capacitance and resistance of the tactile sensor. The tactile sensor was fabricated by depositing the IZO electrodes on a polycarbonate substrate (a thin layer). The IZO was characterized through X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and ultraviolet–visible (UV–vis) spectroscopy techniques. The sensor’s electrical properties were characterized using an LCR meter, i.e., capacitance and resistance were measured in intervals with respect to changes in the applied force on the sensor at 1 kHz operational frequency. The sensor expressed high sensitivity with quick response and recovery times. The sensor also expressed long-term stability. For the analysis of capacitance and resistance, two statistical approaches, i.e., classical and neutrosophic approaches, were applied, and the better analysis approach for the sensor was found.

“…[27][28][29][30] In recent years, the emergence of self-sensing variablestiffness (SSVS) AMs has provided new ideas for the development of robots. [31] The designs that integrated actuation with variable stiffness and sensing have significantly simplified the robot construction [32,33] and represent a step change in the development of soft robots. It envisaged that developing variable-stiffness AMs embedded with sensing functions can dynamically detect deformation and forces, and thus selectively adjust the stiffness.…”

Soft robots have better flexibility than their rigid counterparts thus offering greater adaptability to changing environments. These robots made from flexible materials are generally with low stiffness and have limited capability to perform tasks that require the application of large forces. Soft artificial muscles (AMs) with variable stiffness are promising solutions for soft robots to handle larger payloads. However, the existing actuators need to overcome their small range of stiffness variation and slow response. Further, it is difficult to integrate self‐sensing into existing actuators. Herein, a novel electric AM with variable stiffness and self‐sensing referencing smooth muscle contraction in nature is proposed. The AM consists of two pieces of soft anode mesh, a flexible cathode and a polyvinyl chloride (PVC) gel dielectric layer, where the cathode is also a resistive sensor. The stiffness variation is induced by the friction change caused by electrostatic adsorption. Compared with the existing PVC gel actuation technology, the new design integrated the dielectric and the cathode layers and combined the sensing function. Also, the rigid anode and cathode are replaced by the soft ones, respectively, which makes the AM suitable for soft robotics or wearable devices.
