“…Recently, an electronic skin based on a dual‐excited pressure memory (DPM) matrix has been demonstrated, as illustrated in Figure 8d. [ 144 ] In the DPM device, the piezo‐organic light‐emitting diode (piezo‐OLED) array and piezo‐memristor array were stacked together, which can display the tactile information and memorize the applied pressure by transforming the pressure to resistance signals. The zinc oxide nanowire (ZnO NW) was used in the piezo‐OLED array for the real‐time display of the position and intensity of the applied force caused by the piezo‐phototronic effect.…”

A virtual world has now become a reality as augmented reality (AR) and virtual reality (VR) technology become commercially available. Similar to how humans interact with the physical world, AR and VR systems rely on human–machine interface (HMI) sensors to interact with the virtual world. Currently, this is achieved via state of‐the‐art wearable visual and auditory tools that are rigid, bulky, and burdensome, thereby causing discomfort during practical application. To this end, a skin sensory interface has the potential to serve as the next‐generation AR/VR technology because skin‐like wearable sensors have advantages in that they can be ultrathin, ultra‐soft, conformal, and imperceptible, which provides the ultimate comfort and immersive experience for users. In this progress report, nanowire‐based soft wearable HMI sensors including acoustic, strain, pressure sensors, and physiological sensors are reviewed that may be adopted as skin sensory inputs in future AR/VR systems. Further, nanowire‐based soft contact lenses, haptic force, and thermal and vibration actuators are covered as potential means of feedback for future AR/VR systems. Considering the possible effects of the virtual world on human health, skin‐like wearable artery pulses, glucose, and lactate sensors are also described, which may enable imperceptible health monitoring during future AR/VR practices.

“…In addition, service life, linearity, hysteresis, and creep properties are the criteria for evaluating force sensors, and efforts should be made to optimize these properties while maximizing sensitivity, induction range, and response time. [50][51][52] The practicability of sensors is also a complex but powerful evaluation criterion. Appropriate volume, sufficient stability, and a wide working range are the criteria we need to consider.…”

“…In comparison to vision, smell, taste, and hearing, haptics is more complex to replicate since it requires high‐spatial‐resolution, high‐sensitivity, rapid reaction, and large scale array of pressure sensors [5–12] . Several groups have demonstrated arrays of pressure sensors composed of assembled nanowires, organic transistors, or microstructured rubber layers based on capacitive or resistive variations [13–20] . These have been implemented to distribute strain in the form of a matrix with millimeter‐level resolution [13–21] …”

Pressure sensing simulation using high resolution electronics is important in future robot and human-computer interactions. In this research, we prove that the two-dimensional distribution of strain can be mapped using an array of piezoelectric organic light-emitting diode (piezo-OLED) pressure sensors. Each dot is made up of a piezo-ZnO/TAZ OLED, whose emission intensity is determined by the local strain with piezoelectric photoelectric effect. Reading out the electroluminescence signal with a temporal resolution of 100 ms produces the pressure intensity. Individuality signature and artificial skin technology for optical MEMS and bioimaging can benefit from the device's ability to digitally image mechanical impulses via optical methods.
