“…In Figure e, the small changes in pressure were highly similar to piezoelectric noise from static or small loading fluctuations, proving the detectability of a piezoelectric sensor in tire pressure monitoring. Compared to the latest triboelectric tire pressure sensing system with signals obtained only under the two-electrode contact, the piezoelectric type can give a pressure response at any time and any loading place as long as the tire was under force, which was an innovative way for pressure sensing . Further, the pressure changes at different frequencies and stress were observed.…”

Energy scavenging from irregular human motion and the value-added application for a broad range of pressure sensing are gaining attention in wearable electronics and artificial intelligent systems. Here, we designed a bionic interlocking-structured polyvinylidene fluoride/zinc oxide-grafting barium titanate (PVDF/ZnO-g-BT) piezoelectric nanogenerator (PENG) for energy harvesting from human motion and tire pressure monitoring. First, a two-step hydrothermal method was utilized to align uniformly distributed ZnO nanowires onto the BT surface, forming bionic “sea-urchin” (SU) structured ZnO-g-BT. The ZnO nanowires that aligned on the surface can collaborate to facilitate the deformation of BT and endow the molded PVDF/ZnO-g-BT composites with some figures of merit, such as a fast piezoelectric response of ∼61 ms, superior sensing sensitivity of ∼130 mv/kPa, and excellent stability. Taking advantage of these, the potential application was explored by mechanical energy harvesting from irregular human motion and tire pressure sensing. The excellent electric performance enabled in-time feedback of various useful signals, directing for human motion and tire pressure monitoring. Due to the universal applicability of polydopamine (PDA) coating on any irregular-shaped matrix and easy fabrication of following hydrothermal growing of ZnO nanowires onto the PDA surface, this micro/nano-structure design method can be extended easily to any other organic or inorganic matrix for advanced applications. Undoubtedly, this work provides a simple structure design perspective toward multifunctional wearable electronics and opens a new avenue for piezoelectric sensing.

“…[365][366][367][368] Figure 18a presents a triboelectric bicycle tire (TBT) that utilizes the mechanical motion of a rolling tire for waste energy scavenging and pressure sensing. [369] To avoid instability due to repeated friction, vibration, and other external factors, a reliable TBT has been proposed and developed, which consists of a rubber-based tire thread, inner tube, and a PTFE-Al layer inserted between them. The fully packaged TENG can generate electrical output without occupying extra space and induce minimal degradation of the mechanical properties of the tire, which can still generate an output voltage of 34 V after 120 000 cycles.…”

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...

Triboelectric nanogenerators (TENG) are representative mechanical energy harvesters that can easily generate electricity based on contact electrification and electrostatic induction. However, most TENGs have low mechanical and electrical output stabilities because of their unstable structures, in which separate TENG devices are attached to the outside surface of commercial products/items for application. Herein, a commercial soccer ball‐integrated triboelectric nanogenerator (CSB‐TENG) is proposed as a potential solution. The CSB‐TENG is designed with an electrode‐fully packaged all‐in‐one structure; thus, it can have remarkable mechanical and electrical output stability for 160,000 cycles. For one bouncing motion, the CSB‐TENG generates a maximum peak power of 480 μW. The working mechanism of the CSB‐TENG was established by considering the actual motion of a soccer ball (kicking, bouncing, and rolling). The electrical output of the CSB‐TENG was evaluated and analyzed based on various design and environmental variables (ball material, shoe material, ground material, impact force, ball drop height, and electrode size) in daily life. The CSB‐TENG demonstrated applications, including LED array illumination and capacitor charging tests.This article is protected by copyright. All rights reserved.
