“…According to the triboelectric sequence of common materials, the electronegativity of PDMS is higher than that of PVA; when PVA came into contact with PDMS, PVA lost electrons and became positively charged, and PDMS, meanwhile, gained electrons to be negatively charged. As the external stress was removed in the device, the triboelectric materials fully separated and returned back to the initial state (Figure b(IV)); as a result, the original shape of the device was regained, and the equilibrium state was again obtained with the disappearance of material deformation. − Notably, electrons of the positive electrode tended to move to the negative electrode due to the difference in electric potential. The measured value is called the output voltage, which was tested by an oscilloscope.…”

A triboelectric nanogenerator (TENG) collects thriftless mechanical energy from the surrounding environment and transforms it into electrical energy. This work demonstrated a feasible method for metallizing the polylactic acid (PLA) surface, which was subsequently used as a biomaterial-based TENG electrode material. We demonstrated that microcellular holes and hydrophilic groups (−C-OH and −COOH) were introduced on an alkali-treated PLA sheet surface, subsequently used to absorb Pd 2+ by means of covalent bonds, which could serve as catalytic centers for the reduction of Ni 2+ . Of note, the Ni-layer deposition mechanism represents a typical island-like growth pattern. To be precise, a Ni-coated PLA sheet was fabricated successfully and used as a TENG electrode material. The device had excellent performances, with a maximum output voltage of about 5.1 V, obtained from 6% strain (the corresponding stress is 32.4 kPa) on the PDMS layer. Furthermore, it revealed that under a stress of 0.14−32.4 kPa and strain of 1.3−6%, a linear regression relation existed between the output voltage and the dielectric material strain, and it was found that the density of electrostatic charge formed on the TENG material surface is 4.1 × 10 6 C/m 2 . Additionally, the as-fabricated TENG equipment was attached to various positions of the human body and lab to demonstrate the electrical energy obtained from the mechanical movement. It was also used for real-time demonstrations as a self-powered body-tracking device application which may be beneficial in tracking human position counters during self-powered and emergency exercise movements.

“…Accordingly, the output voltage, current, and power of TB-TENG further increase to 186 V, 4.6 μA, and 34 μW, respectively (Figure g,h and Figure S5). The corresponding charge density reaches 16.5 nC/cm 2 , which is comparable to that of TENGs based on commonly used fluorine-containing polymer materials. ,, A comparison between TB-TENG with previously reported waste-material-based TENGs is also made and shown in Table . − ,− It can be seen that the output charge density of TB-TENG is in a leading position among waste-material-based TENGs.…”

“…As such, if recycled or reused plastic materials can be introduced into the TENGs, green manufacturing can be achieved to efficiently solve the environmental problem and support the sensors’ running as well. From this point of view, there have been many reported green TENGs (W-TENGs) via reusing wasted plastics such PVC, PTFE, PS, PET, PP, and so on for self-powered systems. However, some pressing issues such as low output charge density always impede W-TENGs to go further in real applications.…”

A waste-plastic-material-based triboelectric nanogenerator (W-TENG) from green manufacturing technology is urgently needed in response to sustainable development of smart cities. However, the low output charge density of the previous W-TENGs impedes them from going further in real applications. Toward this issue, an attractive PP/PS composite tribo-layer entirely based on wasted materials is developed in this work. Benefiting from the synergistic effect of the excellent tribo-negative property of PP and strong charge trapping ability of PS, a discarded take-out-box-based TENG (TB-TENG) with high output charge density is presented. The maximum output charge density of TB-TENG reached 16.5 nC/cm2, which is in a leading position among waste material based TENGs and comparable to that of TENGs based on commonly used fluorine-containing polymer materials. To apply in a smart city, we have remodeled the TB-TENG as a smart energy floor to power multiple functional electronics, such as LEDs, a household hygrometer, and a wireless lighting system through harvesting energy from human or vehicle movement. Moreover, an approach of on-road vehicle speed detection is also established when the TB-TENG serves as a self-powered speed sensor in traffic surveillance systems. This work demonstrates a promising example of using a waste take-out box to design a high output and ecofriendly TENG.

This paper discusses the environmental problems posed by medical plastic waste produced in healthcare facilities and explores a suitable way to reutilize the waste through triboelectric nanogenerator (TENG) device technology. Remarkably, the study investigates the potential of medical waste saline bottles to create energy-harvesting, health-monitoring devices and tactile, humidity-sensing applications. Saline bottle sheets are used as triboelectric material to fabricate a TENG in vertical contact separation (VCS) and single electrode (SE) modes. The VCS-TENG produced a power density of 8.78 W/m2 and could power various devices, including 420 red LEDs and portable electronic devices. Sleep monitoring experiments were performed by using an implanted TENG inside the pillow. The SE mode of TENG produced a power density of 1.46 W/m2 and was demonstrated for tactile sensing applications. The present work suggested using medical waste to make health monitoring, tactile sensing, humidity sensing, and energy-harvesting devices and possible applications in touch sensors for various security applications, human–machine interfaces, and IoTs. The proposed idea of using medical waste for TENG fabrication can be further extended to other nontoxic waste plastic generated in the medical field.
