“…As shown in Figure (f) and demonstrated in SI video V9, the intensity of the LEDs output increased with the number of fingers touching the SB sheet surface, indicating an increase in the effective contact area for triboelectrification and resulting in a higher electrical output. It is worth noting that few studies have investigated tactile sensing with waste-based TENG devices in the literature . Therefore, this report adds value to existing studies by providing valuable insights into the tactile sensing capabilities of the waste-based TENG device.…”

“…Interestingly, similar trends have been reported in the literature when investigating the effect of different gloves with a threelayer face mask. 33 In those studies, nitrile gloves consistently demonstrated higher output than latex and vinyl gloves. The higher output of nitrile gloves was due to the higher electron positivity and relative permittivity than latex and vinyl gloves.…”

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.

Triboelectric nanogenerators (TENGs) are becoming attractive devices for harvesting mechanical energy. 3D printing (3DP) is a newly reported technique for the development of this device. This technique is not fully explored for the fabrication of triboelectric materials and compatible printing processes. Herein, three main 3DP techniques including powder‐based multijet fusion, resin‐based polyjet fusion, and filament‐based fused deposition modeling are utilized to investigate new sets of 3DP triboelectric materials. Mechanical to electrical conversion efficiency of 3D printed and commercially available negative and positive triboelectric materials are compared and investigated. Polyamide ‐12 (PA12), Veroclear, acrylonitrile‐styrene‐acrylate (ASA), copper‐coated polylactic acid (Cu‐PLA), polycarbonate (PC), and polyethylene terephthalate glycol (PETG) are fabricated using compatible 3D printing techniques. 3D‐printed PA12 is considered as a reference positive triboelectric layer. Meanwhile, 3D‐printed Veroclear, ASA, Cu‐PLA, PC, PETG, and commercial materials like Teflon sheets, PA6,6 conductive sheets, indium tin oxide‐coated polyethylene terephthalate, conductive‐nylon sheets, and PVDF membrane are selected as negative triboelectric materials. The maximum AC voltage of 80 V and maximum instantaneous current of 0.9 μA are produced by pairing 3DP‐PA12 and 3DP‐Veroclear under open circuit condition. This AC output is further converted to DC output using brdige rectifier circuitry to efficiently charge up the capacitor and glow series of 16 LEDs.

The anti-glare panels along highways can block the dazzling lights of opposing vehicles at night, playing an important role in the highway safety. Inspired by the highway anti-glare panels, wind energy harvesting triboelectric nanogenerator (AG-TENG) arrays to properly capture energy from highway moving vehicles is developed. A single AG-TENG installation module can achieve a high power density of 0.2 Wm −2 at a wind speed of 3 m s −1 . This wind speed is too low to drive conventional wind energy harvesting equipment. The performance of the AG-TENG shows no degradation after 80 h of continuous operation (1 440 000 times). Thus, with the rational consideration and features, the system can generate enough power to drive internet of things (IoT) devices and environmental sensors, as well as offer wireless alarming and radio frequency identification vehicle monitoring. This study provides a promising strategy to properly harvest wind energy on highways using existing infrastructures under the condition of even no natural wind, showing broad application prospects in distributed environmental monitoring, intelligent highways, and the IoT.
