“…Since invented in 2012, triboelectric nanogenerator (TENG) has been proved to be an effective energy conversion technology that can convert mechanical energy in the environment into electrical energy [22][23][24][25], which has been widely applied in the fields of micro/nano power sources [26,27], self-powered sensing [28,29], blue energy [30,31], and high voltage sources [32,33]. Specifically, the coupling between the triboelectric potential generated by TENG and semiconductor devices enables tuning of the carrier transport, thereby establishing an active interaction mechanism between the environment and electronics, thus initiating an emerging field of tribotronics [34][35][36].…”

As key components of artificial afferent nervous systems, synaptic devices can mimic the physiological synaptic behaviors, which have attracted extensive attentions. Here, a flexible tribotronic artificial synapse (TAS) with bioinspired neurosensory behavior is developed. The triboelectric potential generated by the external contact electrification is used as the ion-gel-gate voltage of the organic thin film transistor, which can tune the carriers transport through the migration/accumulation of ions. The TAS successfully demonstrates a series of synaptic behaviors by external stimuli, such as excitatory postsynaptic current, paired-pulse facilitation, and the hierarchical memory process from sensory memory to short-term memory and long-term memory. Moreover, the synaptic behaviors remained stable under the strain condition with a bending radius of 20 mm, and the TAS still exhibits excellent durability after 1000 bending cycles. Finally, Pavlovian conditioning has been successfully mimicked by applying force and vibration as food and bell, respectively. This work demonstrates a bioinspired flexible artificial synapse that will help to facilitate the development of artificial afferent nervous systems, which is great significance to the practical application of artificial limbs, robotics, and bionics in future.

as the components of the IoT network, and they will generate massive data with multidimensions, higher velocity, and improved heterogeneity. [2] Benefiting from this, our world is developing toward a smarter and more well-knit green earth, covering essential blocks like smart homes, smart agriculture, smart cities, smart industries as well as outer space and airlines. [3] In the green earth, the IoT systems are promising to be spread in every smart area, consisting of various sensing modules, signal processing modules, power management modules, power supply modules, etc. Sensing modules are applied to collect abundant information from the target objects or environment, such as temperature, humidity, light intensity, gas concentration, pressure, etc. And the signal processing modules help with the data transmission, processing, and analysis to connect and exchange information with other devices or systems to provide an optimal command to the target object or environment. In addition, the power management modules and power supply modules are to provide the most efficient solutions to reduce the overall power consumption in the operations of the IoT systems. [4][5][6] Thus, looking at the whole earth, it is to be closely connected with the IoT systems, enabling information transfer and communication over the strong network.Narrowing down to a single object like the human body, a single animal, or a robot, wearable electronics have attracted increasing research interest owing to their promising applications in real-time and precious monitoring and tracking of user's preferences and habits on the green earth. [7][8][9][10] Conventional wearable electronics involve smart watches, smart glasses, smart helmets, etc., while most of them are fabricated from nonflexible or rigid materials, resulting in limited wearable comfort, device lifetime, latency response, and loss of sensing information. [11][12][13] To address these issues, the current research focuses on the investigation of sensing materials with flexibility or even stretchability, breathability, washability, lightweight, adhesiveness, etc., enabling improved wearing comfort and long-term wearability. [14][15][16][17] Besides the wearability of the modules in the IoT system, energy issue is within wide research interest and concern as one of the urgent issues contemporarily. Batteries, as the dominant choices for power supply modules, are now revealed asThe advancement of the Internet of Things/5G infrastructure requires a lowcost ubiquitous sensory network to realize an autonomous system for information collection and processing, aiming at diversified applications ranging from healthcare, smart home, industry 4.0 to environmental monitoring. The triboelectric nanogenerator (TENG) is considered the most promising technology due to its self-powered, cost-effective, and highly customizable advantages. Through the use of wearable electronic devices, advanced TENG technology is developed as a core technology enabling self-powered sensors, power supplies, and data comm...

Solid‐liquid triboelectric nanogenerators (SL‐TENGs) are a new technology that combines contact electrification (CE) and electrostatic induction to collect clean energy stored in natural water. Considering their unique advantages of high energy density, wide selection of materials and being suitable for large‐scale promotion, they have attracted more and more attention in recent years, and numerous studies have shown their great potential in various applications. Many critical applications of SL‐TENGs inevitably involve sustained and stable high electrical output. To achieve stable output performance and long cycle life in these applications, the adaptability of SL‐TENGs to material selection, structural design, and working environment is necessary. Therefore, the construction of SL‐TENGs matching different applications has become a critical research direction in TENGs. This review provides a historical summary of the development of SL‐TENGs in the past few years and analyzes the key factors affecting their electrical output performance. The exciting achievements of different constructions of SL‐TENGs for practical applications is also demonstrated such as energy harvesting, self‐powered sensing, and self‐powered cathodic protection. Finally, the development prospects of SL‐TENGs and the significant challenges for their further development is discussed.
