In recent years, there is a meteoric rise in the prevalence of electronic wearables, and flexible wearables have attracted tremendous attention in human–machine interfaces due to their high biocompatibility, functionality, conformability, and low‐cost. Flexible magnetic smart skin is part of this rapidly progressing field of flexible wearable electronics, which has paved the way for a new path for human perceptual development, as they may form a new perception, also known as magnetic sense, that is, the capacity to detect and interact with magnetic fields. In this review, the concept of the magnetic smart skin is defined: magnetoelastomers and flexible magnetic sensors. In magnetoelastomers, different sources of magnetic field, structures, and applications are summarized by recent and renowned research. In flexible magnetic sensors, different flexible substrates, sensor types, and applications are also summarized. This review further concludes by discussing the outlook and current challenges of magnetic smart skin in human–machine interfaces.

Applications of robotics-assist surgeries developed rapidly in worldwide biomedical research. Haptic and force feedback is one of the main challenges in current research on surgical robotics. Lack of proper haptic and force feedback in roboticassist surgeries will limit the movement and affect the doctors' judgement. Force sensors play an essential role when collecting and transporting feedback signals, and different sensors have their respective advantages and disadvantages. Based on the haptic and force feedback background related to surgical robots, this article will introduce the main features of different force sensors, including but not limited to traditional sensors like optical-based and recent-developed on-skin sensors. This article will also discuss further how the precision and stability of haptic feedback could be improved and the possible applications of new haptic and force feedback technologies in future studies.

“…Several high-performance nanomaterials, including carbon nanotubes (CNTs) [14], carbon black (CB) [15], graphene oxide (GO) [16], and metal nanoparticles, have been employed as sensitive materials. In addition, polydimethylsiloxane (PDMS), polyurethane (PU), and silicone rubber (SR) exhibit excellent properties, such as exceptional electrical insulation, cflexibility, and biocompatibility, which enable them to be widely used as flexible substrates for wearable electronics [15][16][17][18][19]. Although conductive nanomaterials and flexible substrates provide an important foundation for the preparation of flexible 3D force tactile sensors, the manufacturing of sensors exhibiting high sensitivity, excellent cycling stability, and fast response based on simple and low-cost preparation processes still faces huge challenges.…”

The development of a high-performance, low-cost, and simply fabricated flexible three-dimensional (3D) force sensor is essential for the future development of electronic skins suitable for the detection of normal and shear forces for several human motions. In this study, a sandwich-structured flexible 3D force tactile sensor based on a polyethylene-carbon composite material (velostat) is presented. The sensor has a large measuring range, namely, 0–12 N in the direction of the normal force and 0–2.6 N in the direction of the shear force. For normal forces, the sensitivity is 0.775 N−1 at 0–1 N, 0.107 N−1 between 1 and 3 N, and 0.003 N−1 at 3 N and above. For shear forces, the measured sensitivity is 0.122 and 0.12 N−1 in x- and y-directions, respectively. Additionally, the sensor exhibits good repeatability and stability after 2500 cycles of loading and releasing. The response and recovery times of the sensor are as fast as 40 and 80 ms, respectively. Furthermore, we prepared a glove-like sensor array. When grasping the object using the tactile glove, the information about the force applied to the sensing unit can be transmitted through a wireless system in real-time and displayed on a personal computer (PC). The prepared flexible 3D force sensor shows broad application prospects in the field of smart wearable devices.
