“…where V oc is the voltage, x is the change of the distance between the polytetrafluoroethylene (PTFE) and film surfaces, k is the elastic coefficient of the material, P is the applied pressure, and S is the device area. From equation ( 1), it can be seen that the voltage has a linear relationship with the pressure [37].…”

Flexible pressure sensors, as an essential component of E-skin, have been applied in health monitoring and human-machine interface. However, the limited measurement range hinders their applications and developments. Herein, we present a tri-mode flexible porous pressure sensor with an ultra-wide measurement range (0.91 Pa-30 MPa) based on the triboelectric effect, piezoresistive effect, and mechanoluminescent (ML) effect. The low-pressure area (0.91 Pa-450 Pa) response was realized by a single-electrode triboelectric nanogenerator (SE-TENG), which consists of polydimethylsiloxane (PDMS) and silver nanowire (Ag NWs). The medium-pressure area (0.45-1.8 kPa) was probed by the piezoresistive sensor using Ag NWs conductive network on the porous surface. ML phosphors (SrAl2O4:Eu2+, Dy3+, SAOED) blended in the PDMS matrix of porous pressure sensor were utilized to respond to the high pressure (1 MPa-30 MPa). This flexible pressure sensor possesses excellent stability with over 20000, 5000, and 2000 cycles in different pressure measurement ranges, respectively. Finally, a tactile glove with the tri-mode flexible porous pressure sensor was carried out and demonstrated various responses to different pressure conditions. This ultra-wide range tri-mode flexible sensor would provide a widely adaptable platform for human-machine interactions in the Internet of Things (IoT).

Hybrid piezoelectric‐triboelectric nanogenerators (HPTNGs) are a new energy storage device that combines the benefits of both technologies. This technology can revolutionize energy storage and bring down solar and renewable costs. HPTNGs are becoming increasingly popular in the wearable technology market due to their unique characteristics. HPTNGs feature hybrid piezoelectric and triboelectric modes, allowing them to generate electricity from low voltage and sound waves. This combination gives them a higher performance than either type of generator, making them ideal for applications such as mobile banking, health monitoring, and smart home control. This article begins with a discussion on the structural configuration of hybrid HPTNGs, followed by describing their coupling effect and applications in wearable technology. Furthermore, it also focuses on the challenges, possible solutions, and prospects of this device in the wearable industry.

With the rapid development of the Internet of Things (IoTs), numerous distributed wide‐area low‐power electronic devices have been utilized in various fields, such as wireless monitoring sensors and wearable electronics. Due to the dispersion and mobility of microelectronic devices, their energy supply faces serious challenges. The inconvenience and non‐environmental friendliness of using traditional centralized low entropy energy and chemical batteries to power distributed microelectronic devices are becoming increasingly prominent. Environmental energy harvesting technology with high entropy characteristics is considered an effective solution for low‐power electronic devices. This paper comprehensively reviews the recent progress in microelectronic technologies based on energy harvesting and signal sensing. First, state‐of‐the‐art micro‐power electronic devices in humans, animals, and the environment are introduced. Secondly, the available micro‐energy sources in the environmentare elaborated and summarized. Then, the principles and characteristics of ambient microenergy harvesting technologies based on different mechanisms are classified, summarized, and analyzed. In addition, this work comprehensively summarizes the applications of self‐powered micro‐electronics technology in 11 different fields, including human, animal, and environment. Finally, research challenges, technical difficulties, and research gaps in self‐powered microelectronics based on micro‐energy harvesting technology are discussed and summarized.
