“…Noticed that the resistance error measured at different angle are varied around an average value of 35 Ω (Figure S10, Supporting Information), which corresponds to a shear angle resolution of 7.3°. This performance is regarded as competitive with some recently reported works, [ 27,44,48 ] and further improvement can be achieved by adjusting the material electrical resistivity, which is promising for shear angle measurement in robotic applications. However, a dead zone of approximately 15° also exists due to the designed gap of the circular resistor.…”

Flexible force sensors have been widely applied in robotics for object exploring, remote controlling, and human–machine interactions. The tri‐axis force sensors for accurate measurement of normal and shear forces are generally in urgent demand. Most tri‐axis force sensors rely on signal analyzation between multiple elements to achieve force components, which may need numerous leading wires and limit the force angular sensing performance. Herein, a novel flexible centralized force sensor is developed based on a novel tri‐axis force refactoring method. Normal force is detected by the central parallel‐plates capacitor, and both the angle and amplitude of shear force can be extracted through the resistance changes. The normal force performance is characterized with a sensitivity of 0.057 N−1 and a detection range of 0–12 N, and the effective detection range of shear force is about 0.5–0.67 N. The minimum distinguished shear angle difference is about 7.3°, which can be further improved by increasing the sensing material's resistivity. Then, robotic grasping tests are performed and show that the sensor can accurately measure the normal and shear forces and applied shear force angle, which indicates its promising applications in potential robotic manipulation and interactions.

“…The sensor can generate a voltage of up to 1.613 V in an open circuit, and in a short circuit, it produces a current of 47.31 mA/m 2 under a pressure value of 612.50 kPa. Another flexible sensor that was inspired by fingertips was made with a triboelectric sliding sensing mechanism [106]. It could sense sliding pressure caused by friction as well as normal stress applied to it.…”

Purpose of Review Soft electronic skins (E-skins) capable of tactile pressure sensing have the potential to endow robotic systems with many of the same somatosensory properties of natural human skin. In this progress report, we review recent progress in creating soft tactile pressure sensing skins to give robots a sense of touch that resembles human skin sensing.Recent Findings For soft tactile pressure sensing skins, researchers have focused on five main sensing principles: (1) resistive; (2) capacitive; (3) magnetic; (4) barometric; and (5) optical. The combination of these traditional sensing techniques, along with the use of soft materials such as liquid metal and magnetic elastomers, has improved the perception capabilities and mechanical characteristics of artificial skin. In addition, the implementation of artificial intelligence and machine learning algorithms for data processing give robotic systems with these soft sensing skins an enhanced sense of touch.Summary E-skins for tactile sensing have a central role in a range of robotic applications, from haptics and teleoperation to bio-inspired soft robots. For many of these applications, E-skins must be soft, thin, flexible, stretchable, and lightweight so that they can be mounted on a robot, incorporated into clothing, or placed on human skin without interfering with mobility or contact mechanics. Significant research has been conducted on sensing techniques that can allow a robot to achieve a sense of human touch, with important progress being made in force feedback sensing, texture recognition, and spatial acuity. We begin by covering principles of tactile sensing in humans, robotics, and human-machine interaction. This is followed by an overview of soft material transducers capable of pressure and force sensing. This includes resistive, capacitive, magnetic, barometric, and optical sensing techniques. We close with a summary of emerging trends in sensor design and implementations for applications in robotics.
