“…In Figure 6b, Wang et al [43] reported a highly sensitive multi-dimensional sensor to detect force from multi directions which revealed great potential as electronic skin sensors. More recently, as presented in Figure 6c, Wang and his team [44] designed and fabricated a self-powered linear and rotary coupled motion sensor with a more complicated structure, the velocity monitored in different motions revealed good linearity with most error rates lower than 3%. Regard to multi motion detection as robotic hands, triboelectric sensors have shown reliable accuracy and high designability which makes it a potential candidate in artificial intelligence industries.…”

With the rapid development of industry and information technology, rough challenges have been put forward for the traditional sensor technology to meet the increasingly complex and diverse application demands in actual production and daily life, and the widely distributed sensor network also faces complex power supply and maintenance problems. As a new energy conversion technology, triboelectric nanogenerators (TENGs) based on triboelectrification and electrostatic induction effect can respond to the weak mechanical stimuli in the surrounding environment and generate corresponding electrical signals to realize the sensing function without external power supply. In addition, TENGs have the advantages of wide selection of fabrication materials, flexible and diverse fundamental modes, which can be customized for different applications and realize different sensing functions. In recent years, triboelectric sensors based on TENGs have developed rapidly, and researchers have developed variable triboelectric sensors for different application scenarios. In this paper, the developed triboelectric sensos have been classified into different categories, the advanced strategy to prepare advanced triboelectric materials and technology used for manufacturing integration have been introduced. This work summarizes the main applications of triboelectric sensors and put forward the current challenges, so as to provide guidance and instructions for the future development of triboelectric sensors.

Capacitive pressure sensor (CPS) is widely used in the field of industrial equipment, because of the merits of fast dynamic response and high resolution. However, the traditional laminated CPS makes it difficult to achieve a wide detection limit in a small size, and this structure is susceptible to electromagnetic interference. Here we developed a miniature planar capacitive pressure sensor (MPCPS) with high performance, which can realize the response to external touching stimuli through the deformation of the packaging material and the change of the equivalent resistance. A metal shielding layer was added under the insulating substrate to effectively isolate the external interference. The thickness of the sensor is about 200 μm, and the diameter of the core sensing area is less than 1 mm. Two types of electrodes with different shapes were designed, among which the spiral electrode MPCPS has better performance than the linear electrode MPCPS. The spiral electrode MPCPS has a high sensitivity of 99.2% MPa-1 in the low-pressure range (0 ~ 0.1 MPa), fast response (20 ms), wide detection limit (>1 MPa), and high durability (>2000 cycles). In addition, MPCPS is proven to have good resistance to high temperature and oil contamination. Finally, practical applications such as contact pressure measuring on the meshing surface of spur gears and mechanical gripper clamping force monitoring were successfully demonstrated. These results shed light on the potential application of the MPCPS in the pressure detection of industrial equipment.

“…There are few energy-harvesting technologies developed for sustainable operations such as solar cells and thermoelectric generators that are operated based on the sunlight and temperature gradient, respectively. However, the aforementioned power sources cannot ensure uninterrupted power supply to the wearable electronic devices due to the sunlight interruptions and low thermal power generation from the human body. − Thus, developing new energy-harvesting sources that can solve these drawbacks to offer sustainable power supplies for portable and wearable electronic devices is of great significance. − …”

Recent advancements in wearable electronic technology demand advanced power sources to be flexible, deformable, durable, and sustainable. An ionic-solution-modified conductive hydrogel-based triboelectric nanogenerator (TENG) has advantages in wearable devices. However, fabricating a conductive hydrogel with better mechanical and electrical properties is still a challenge. Herein, a simple approach is developed to insert ion-rich pores inside the hydrogel, followed by ionic solution soaking. The suggested ionic conductive hydrogel is obtained by cross-linking the polyvinyl alcohol (PVA) hydrogel and carboxymethyl cellulose sodium salt (CMC), followed by soaking in the ionic solution. Furthermore, a flexible and shape-adaptable single-electrode TENG (S-TENG) is fabricated by combinations of ionic-solution-modified dual-cross-linked CMC/PVA hydrogel and silicone rubber. Additionally, the effects of the CMC concentration, type of ionic solution, and concentration of optimized ionic solutions on the hydrogel properties and S-TENG output performance are studied systematically. The well-dispersed CMC- and PVA-based hydrogel provides ion-rich pores with high ion migration, leading to enhanced conductivity. The fabricated S-TENG delivers maximum output performance in terms of voltage, current, and charge density of ∼584 V, 25 μA, and 120 μC/m2, respectively. The rectified S-TENG-generated energy is used to charge capacitors and to power a portable electronic display. In addition to energy harvesting, the S-TENG is successfully demonstrated as a touch sensor that can automatically control the light and the speaker based on human motions. This investigation provides a deep insight into the influence of the hydrogel on the device performance and gives a guidance for designing and fabrication of highly flexible and stretchable TENGs.
