Recently, nanogenerators (NG) have attracted considerable attention due to the practical applications of converting mechanical energy to electrical energy from various sources. [1-5] Piezoelectric materials generate electricity by generating dielectric polarization when a physical force is applied. A piezoelectric nanogenerator (PENG) based on piezoelectric materials can convert various mechanical energy sources into electrical energy without generating contaminants, and they can be easily miniaturized and are light in weight, so they can be installed where vibration and pressure energy exist. [6,7] Various non-centrosymmetric piezoelectric materials such as lead zirconate titanate (PZT), [8-12] quartz, [13] zinc oxide (ZnO), [3,14-16] barium titanate (BaTiO 3 , BTO), [17-22] zinc sulfide (ZnS), [23-24] polyvinylidene fluoride (PVDF), [25,26] etc. are widely used for PENGs. Among them, wurtzite structured ZnO nanorods (NRs) have undergone numerous studies due to their unique features, such as their piezoelectricity, semiconducting property, transparency, biocompatibility, and low manufacturing cost. [3,13-16] ZnO NRs are an intrinsic n-type semiconductor due to native defects such as zinc (Zn) interstitials and oxygen (O) vacancies. Excessive free electrons from the defects in ZnO NRs limit their harvesting performance due to the screening of piezoelectric potential when mechanical stress is applied. To solve this issue, several approaches have been reported, for example, thermal annealing, [27] O 2 plasma treatment, [28,29] and p-type semiconducting layer coating [30,31] to reduce native defects or modulate carrier concentration. In a previous work, NiO was used as a p-type semiconductor in connection with doping materials research to enhance the output performance of ZnO-based PENGs. [30] The oxidation temperature of Ni for making NiO is very high, however, from 500 to 900 C, so there is a disadvantage in that its use on a

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.

In this work, Zinc Oxide based Piezoelectric Nanogenerator (PENG) over the flexible Kapton Polyimide (PI) substrate has been developed. The device performance has been improved by laser texturing of PI substrate which has increased the effective surface area of PI and adhesivity of ZnO thin film with PI substrate to improve the reliability and lifespan of the device. The untextured PI based PENG has generated a peak‐to‐peak output voltage, current, and power of 6 V, 420 nA, 2.42 μW, respectively, which has increased to 15.8 V, 790 nA, and 12.51 μW, respectively, on using textured PI obtained by 60% laser spot overlap. On further increasing the laser spot overlap to 80%, the peak‐to‐peak output voltage, current, and power have improved to 22.2 V, 1210 nA, and 26.88 μW, respectively. Therefore, as compared to the untextured polyimide‐based PENG, laser textured polyimide based PENG is a promising candidate for energy harvesting applications.This article is protected by copyright.
