“…The varying curves were distinguished due to the velocities, which were displaying step‐up outputs. The maximum output power at different velocities occurred at a set of specific loads, shown in Figure d, and the slight displacement of the power peak was observed from the larger loads to smaller loads with increasing velocity, which was in accord with the previous reports …”

Private and security information for personal identification requires an encrypted tool to extend communication channels between human and machine through a convenient and secure method. Here, a triboelectric‐based transparent secret code (TSC) that enables self‐powered sensing and information identification simultaneously in a rapid process method is reported. The transparent and hydrophobic TSC can be conformed to any cambered surface due to its high flexibility, which extends the application scenarios greatly. Independent of the power source, the TSC can induce obvious electric signals only by surface contact. This TSC is velocity‐dependent and capable of achieving a peak voltage of ≈4 V at a resistance load of 10 MΩ and a sliding speed of 0.1 m s−1, according to a 2 mm × 20 mm rectangular stripe. The fabricated TSC can maintain its performance after reciprocating rolling for about 5000 times. The applications of TSC as a self‐powered code device are demonstrated, and the ordered signals can be recognized through the height of the electric peaks, which can be further transferred into specific information by the processing program. The designed TSC has great potential in personal identification, commodity circulation, valuables management, and security defense applications.

“…On the top and bottom, the whole device was covered by two conductive layers to achieve the charge transfer . Then, the fact is verified successively that formed by different friction materials and/or different structures the TENGs based on triboelectrification and electrostatic inducement have some fair different properties, such as efficiently harvesting mechanic energy, high signal outputs, minimum abrasion, and high removal efficiency for particulate matter . Through the combination of polydimethylsiloxane (PDMS), Kapton, aluminum foil, and pyramid‐feature structure, Wang et al fabricated an arch‐shaped TENG, which suggested that an arch‐bridge shape is quite favorable for the improvement of the electric properties …”

Triboelectric nanogenerators (TENGs), which collect the energy neglected constantly in the daily life of humans, have been applied to various fields, such as energy harvesting, self‐powered sensing, and environmental monitoring. With the growing demand for lightweight, flexible, and portable electric devices, TENGs have become a hot topic. In this work, a flexible, lightweight, and wearable TENG combining a nickel conductive mesh and a perfluorinated ethylene‐propylene film via the ultrasonic‐welding technique is presented. The TENG with an arch‐bridge shape is in possession of plenty of excellent properties, including high output, resistance to destruction, and long‐term stability, which not only owns a maximum power density of 36 mW m−2 at the optimal matching load impedance of 9 MΩ, but can also power a scientific calculator and 19 LEDs connected in series. Furthermore, the TENG could be used as a self‐powered sensor to remotely control the state of electric fans or bulbs through a wireless sensing system.
