“…Therefore, a magnetic multi-dimensional tactile sensor was developed, where the normal and shear forces are naturally decoupled [ 72 ], as shown in Figure 4 e. However, this design is sensitive to the magnetic field interference, and the hall sensor chip used in this design increases the device thickness. A three-dimensional resistive tactile sensor with five bumps responding to forces in five perpendicular directions [ 118 ] and a multi-directional flexible tactile sensor for pressure, shear forces, and strains decoupled sensing were proposed [ 119 ], where the output sensing signals in different directions are independent of one another, as shown in Figure 4 f. Currently, multi-dimensional tactile sensors are required to be thinner and more flexible to be applied to electronic skin and HMI applications.…”

Human–Machine Interface (HMI) plays a key role in the interaction between people and machines, which allows people to easily and intuitively control the machine and immersively experience the virtual world of the meta-universe by virtual reality/augmented reality (VR/AR) technology. Currently, wearable skin-integrated tactile and force sensors are widely used in immersive human–machine interactions due to their ultra-thin, ultra-soft, conformal characteristics. In this paper, the recent progress of tactile and force sensors used in HMI are reviewed, including piezoresistive, capacitive, piezoelectric, triboelectric, and other sensors. Then, this paper discusses how to improve the performance of tactile and force sensors for HMI. Next, this paper summarizes the HMI for dexterous robotic manipulation and VR/AR applications. Finally, this paper summarizes and proposes the future development trend of HMI.

“…Recent advancements in flexible and stretchable electronics technology provide a feasible solution for bionic electronic skin [ 1 , 2 , 3 , 4 , 5 ] and bio-integrated electronics [ 6 , 7 , 8 ]. Specifically, the intrinsic rigid material is thinned and designed as a serpentine ribbon, so that it can withstand large structural deformation with small strain, which can significantly improve the stretchability of inorganic electronics [ 9 , 10 ].…”

Compared with other physiotherapy devices, epidermal electronic systems (EES) used in medical applications such as hyperthermia have obvious advantages of conformal attachment, lightness and high efficiency. The stretchable flexible electrode is an indispensable component. The structurally designed flexible inorganic stretchable electrode has the advantage of stable electrical properties under tensile deformation and has received enough attention. However, the space between the patterned electrodes introduced to ensure the tensile properties will inevitably lead to the uneven temperature distribution of the thermotherapy electrodes and degrade the effect of thermotherapy. It is of great practical value to study the temperature uniformity of the stretchable patterned electrode. In order to improve the uniformity of temperature distribution in the heat transfer system with stretchable electrodes, a temperature distribution manipulation strategy for orthotropic substrates is proposed in this paper. A theoretical model of the orthotropic heat transfer system based on the horseshoe-shaped mesh electrode is established. Combined with finite element analysis, the effect of the orthotropic substrate on the uniformity of temperature distribution in three types of heat source heat transfer systems is studied based on this model. The influence of the thermal conductivity ratio in different directions on the temperature distribution is studied parametrically, which will help to guide the design and fabrication of the stretchable electrode that can produce a uniform temperature distribution.

“…[5][6][7][8] Real-time accurate pulse waveform measurements have a crucial effect for pulse-based health monitoring and diagnosis of CVDs. The current rapid advancement of wearable technologies allows them to provide real-time and continuous pulse wave monitoring, [9,10] based on capacitive, [11][12][13][14][15] piezoresistive, [16][17][18][19] piezoelectric, [20][21][22] triboelectric, [23][24][25][26][27] magnetoelastic, [28][29][30] photoplethysmography (PPG), [31][32][33][34] and ultrasonic. [35][36][37][38] However, these wearable sensors are generally vulnerable to body motion artifacts, leading to inaccurate diagnosis and misinterpretation, [39][40][41][42] which are mainly ascribed to the weak adhesion or poor conformability, and thus inconsistent interfaces between the devices and human skin.…”

Continuously and accurately monitoring pulse‐wave signals is critical to prevent and diagnose cardiovascular diseases. However, existing wearable pulse sensors are vulnerable to motion artifacts due to the lack of proper adhesion and conformal interface with human skin during body movement. Here, a highly sensitive and conformal pressure sensor inspired by the kirigami structure is developed to measure the human pulse wave on different body artery sites under various prestressing pressure conditions and even with body movement. COMSOL multiphysical field coupling simulation and experimental testing are used to verify the unique advantages of the kirigami structure. The device shows a superior sensitivity (35.2 mV Pa−1) and remarkable stability (>84 000 cycles). Toward practical applications, a wireless cardiovascular monitoring system is developed for wirelessly transmitting the pulse signals to a mobile phone in real‐time, which successfully distinguished the pulse waveforms from different participants. The pulse waveforms measured by the kirigami inspired pressure sensor are as accurate as those provided by the commercial medical device. Given the compelling features, the sensor provides an ascendant way for wearable electronics to overcome motion artifacts when monitoring pulse signals, thus representing a solid advancement toward personalized healthcare in the era of the Internet of Things.
