“…Furthermore, in previous works, improving the wave height measurement range usually enhances the charge amount accumulated; [23][24][25]27 however, the accumulation of tribocharge results in the breakdown discharging, which emits electromagnetic wave and brings potential electromagnetic interferences (EMIs) to the signal receiving and analyzing system. 28,29 Recently, several innovative "tribo-photonics" devices toward self-powered sensing were developed, where photons instead of electrons function as the information carrier, eliminating the signal preamplification and EMI issues. Driven by the mechanical friction, the optical properties such as focal length, scattering strength, and emission spectrum can be effectively modulated.…”

Conventional ocean wave observation instruments are powered by batteries, limiting the continuous observation time. Besides, the waste of batteries brings environmental contaminations. Triboelectric nanogenerators (TENGs) can reveal ocean wave information through their electrical output, taking the triboelectric charge as the information carrier. However, charge amplification is necessary, consuming additional energy. Herein, taking the photons rather than electrons as the information carrier, we developed a fully self-powered natural light-enabled sensing system for ocean wave monitoring by coupling two rotary-freestanding sliding TENGs (RFS-TENGs) and a polymer network liquid crystal (PNLC)-triggered optical system. The natural light is modulated by the PNLC driven by ocean wave-induced friction. With the assistance of a one-way bearing, the rise and fall of the wave will trigger different RFS-TENGs to power the PNLC in different voltage drops, leading to different transmitted natural light intensities. The wave height information can be obtained through the number of pulse signals with the same trough light intensity, while the wave period can be obtained through the duration between the same two sets of pulse signals. The effectiveness of the developed sensing paradigm in practical applications was verified by flume-based experiments, with the highest accuracies of 90.7% in wave height and 99.8% in wave period.

“…However, because of the ultralow current of the TENG, the signal preamplification is necessary for the signal processing and transmission, consuming additional energy which is much higher than the energy saved for sensing. Furthermore, it should be noticed that the transferred charge from the TENG to external circuit is extremely trivial (i.e., less than 30 nC for vibrations 34 ), and thus, the sensing performance is easily affected by the EMI such as lightning strikes 37–41 …”

Fiber‐optic sensors have been developed to monitor the structural vibration with advantages of high sensitivity, immunity to electromagnetic interference (EMI), flexibility, and capability to achieve multiplexed or distributed sensing. However, the current fiber‐optic sensors require precisely polarized coherent lasers as the lighting sources, which are expensive in cost and suffer from the power supply issues while operating at outdoor environments. This work aims at solving these issues, through developing a fully self‐powered, natural‐light‐enabled approach. To achieve that, a spring oscillator‐based triboelectric nanogenerator (TENG), a polymer network liquid crystal (PNLC), and an optical fiber were integrated. The external vibration drove the PNLC to switch its transparency, allowing the variation of the incident natural light in the optical fiber. Compared with the majority of conventional TENG‐based active vibration sensors, the developed paradigm does not suffer from the EMI, without requirements of the signal preamplification which consumes additional energy. The vibration displacement monitoring was performed to validate the sensing effectiveness of the developed paradigm.
