Flexible and stretchable electronics have emerged as highly promising technologies for the next generation of electronic devices. These advancements offer numerous advantages, such as flexibility, biocompatibility, bio-integrated circuits, and light weight, enabling new possibilities in diverse applications, including e-textiles, smart lenses, healthcare technologies, smart manufacturing, consumer electronics, and smart wearable devices. In recent years, significant attention has been devoted to flexible and stretchable pressure sensors due to their potential integration with medical and healthcare devices for monitoring human activity and biological signals, such as heartbeat, respiratory rate, blood pressure, blood oxygen saturation, and muscle activity. This review comprehensively covers all aspects of recent developments in flexible and stretchable pressure sensors. It encompasses fundamental principles, force/pressure-sensitive materials, fabrication techniques for low-cost and high-performance pressure sensors, investigations of sensing mechanisms (piezoresistivity, capacitance, piezoelectricity), and state-of-the-art applications.

“…In recent years, people have put forward more requirements for the performance of flexible pressure sensors, so much research has been conducted to improve and optimize the structure and materials of the sensors. On the one hand, many studies have produced and expanded functional materials including carbon nanotubes (CNTs) [30,31], silver nanowires (AgNWs) [32][33][34], graphene [35,36], and so on. On the other hand, by micro-designing the sensor structure, such as pyramids [37][38][39], multi-microholes [40,41], micro-columns [42,43], and so on, the pressure response performance of the sensor can be improved.…”

Due to its conformal capability, the flexible pressure sensor has a wide range of applications in wearable devices, health monitoring, human-computer interfaces, and other fields. Sensors designed according to various principles and application scenarios exhibit a variety of good characteristics such as high sensitivity, high transparency, a wide detection limit, and low crosstalk. However, achieving all these exceptional functions within a single sensor is evidently challenging. Therefore, it is prudent to emphasize specific advantageous features depending on the unique usage environments and application scenarios. This paper first describes the classification of flexible pressure sensors based on their working principle, then summarizes the commonly used materials and sensor characteristics, and finally reviews the application characteristics of flexible pressure sensors based on different application fields and scenarios. The bottleneck challenges encountered in the development of flexible pressure sensors are discussed, and the foreseeable development strategy is predicted.
