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.

“…Hence, there is always a perceptual effort to develop green and sustainable energy sources that can tackle the increasing energy crisis and disposal issues. In 2012, Wang et al proposed the idea of a triboelectric nanogenerators (TENGs) that can effectively convert mechanical energy to electrical energy and emerged as a game-changing invention in the realm of sustainable energy harvesting technology owing to its high energy conversion efficiency, a broad selection of materials, easy device fabrication, and so on. − These TENGs have the potential to complement existing renewable energy sources by capturing energy from underutilized sources such as wind, ocean, human motion, rain energy, and acoustic energy to electrical energy and thus can be used to power up nano and microscale electronic devices. − Additionally, TENGs have been employed to harness energy from various unconventional sources, including wind and tidal energy. , Some reports even highlight the use of TENGs for capturing energy from rainwater drops . Furthermore, certain nanogenerators have been integrated into hybrid energy systems alongside solar cells .…”

Metal−organic framework (MOF) materials have become a potential candidate in the field of triboelectric nanogenerators (TENGs). However, the direct utilization of MOFs in TENG device technology is still a relatively obscured area, with only a limited number of reports addressing this topic. Instead, most of the existing literature investigated composite materials that combine MOFs with polymers or binder materials for TENG fabrication. However, this method does not accurately reveal the actual triboelectric properties of MOFs. Consequently, the direct growth of MOFs on conducting substrates poses a significant challenge in realizing the potential of MOFs in TENG devices. This report addresses this gap by employing a simple, cost-effective hydrothermal method for directly growing ZIF-67 on an aluminum (Al) substrate. The utilization of a ZIF-67-based TENG has yielded impressive results, achieving a noteworthy maximum power density of 2.35 W/ m 2 . This TENG has demonstrated practical applications by effectively integrating into intelligent parking systems and providing power to portable electronic devices. Furthermore, the approach employed in this study can be extended to other MOFs which can be directly synthesized on flexible conducting substrates. This research opens up new possibilities for exploring the inherent triboelectric properties of MOFs and their placement within a triboelectric series.

“…TENGs convert mechanical vibration into electrical energy based on triboelectrification and electrostatic induction, generating alternating current (AC) signals through repeated contact and separation of materials under the mechanical stimulus. − One advantage of TENGs is that they can work with readily available mechanical energy, which is present everywhere. The majority of mechanical signals from the human body use to communicate, such as sound, body movements, and muscle contractions, could also be used in sensors or health monitoring devices with sensitive TENGs. − Therefore, TENGs have been considered to be one of the most successful methods for extracting low-frequency mechanical energy for sensor development. By wearing a TENG device on the body respirator, cardiovascular and physical activity can be monitored.…”

A high-performance triboelectric nanogenerator (TENG) has been proposed as a solution to the low output power issue that has hindered the practical application of TENGs. The high-performance TENG was achieved through the surface engineering of one of the triboelectric layers. The surface engineering is performed using sandpapers of different grit sizes to achieve the required physical surface modification to enhance the performance of the TENG's. The TENG proposed in this study consists of ZnO nanosheets grown on a surface-modified aluminum substrate and a poly(dimethylsiloxane) (PDMS) film as triboelectric layers. The TENG demonstrated a maximum peak−peak voltage and current of 1442 V and 155 μA, respectively, for the hand tapping force. The observed power density of 10.8 W/m 2 at a load resistance of 10 MΩ is the highest reported value for ZnO nanosheet based TENGs reported to date. This higher power density allows the TENG to power up to approximately 824 light-emitting diodes (LEDs) and small electronic devices without the need for any storage element. The TENG was also tested as a wearable device on different parts of the body, where it harvested biomechanical energy and acted as a self-powered respiratory monitoring sensor. Therefore, the proposed TENG has the potential to be used in multifunctional wearable devices and self-powered health monitoring sensors.
