“…Energy harvesting is the act of harnessing energy from external sources such as solar, thermal, or vibrations to produce electricity (Selvan and Ali, 2016). It plays a crucial role in renewable energy generation, and the development of self-powered systems (Harb, 2011;Liang et al, 2023). Vibration, a significant energy source, can be harvested using transduction mechanisms like electromagnetic, electrostatic, or piezoelectric transducers (Vullers et al, 2009;Harb, 2011).…”

The inerter was introduced as a mechanical counterpart to the electrical capacitor, completing the force-current analogy. This is a one-port, two-terminal device in which the equal and opposite forces exerted at its terminals are proportional to the relative acceleration between them. Within this relationship, the “inertance” is the coefficient of proportionality and carries the unit of mass. This implies that the inerter can exert an inertial force at its terminals, effectively representing a virtual mass. Due to these properties, inerters have gained popularity, finding applications as components of vibration control systems and energy harvesters. Derived from passive inerters, semi-active inerters are integrated with active control systems to regulate their inertance. Since their introduction, semi-active inerters have been pivotal in situations demanding active monitoring of natural frequency or control force, generally outperforming their passive counterparts. While numerous significant reviews on passive inerters and their applications have been published in respected journals, dedicated literature reviews on semi-active inerters remain scarce. This review seeks to bridge this gap, offering a comprehensive literature review on semi-active inerters and highlighting research challenges and opportunities. Given the novelty of semi-active inerters, they present a fascinating area of study.

“…Eventually, robots in field operation should be capable of harvesting energy from renewable sources and/or receive energy wirelessly to supplement or replace their on-board energy source. These capabilities aim to reduce the environmental impact of electronic waste and significantly extend the robot’s operational window ( Liang et al, 2022 ). For example, EcoBot III, which has an organic digestive system to power itself, demonstrates the advancements in energy harvesting capabilities in robots.…”

We live in a time of unprecedented scientific and human progress while being increasingly aware of its negative impacts on our planet’s health. Aerial, terrestrial, and aquatic ecosystems have significantly declined putting us on course to a sixth mass extinction event. Nonetheless, the advances made in science, engineering, and technology have given us the opportunity to reverse some of our ecosystem damage and preserve them through conservation efforts around the world. However, current conservation efforts are primarily human led with assistance from conventional robotic systems which limit their scope and effectiveness, along with negatively impacting the surroundings. In this perspective, we present the field of bioinspired robotics to develop versatile agents for future conservation efforts that can operate in the natural environment while minimizing the disturbance/impact to its inhabitants and the environment’s natural state. We provide an operational and environmental framework that should be considered while developing bioinspired robots for conservation. These considerations go beyond addressing the challenges of human-led conservation efforts and leverage the advancements in the field of materials, intelligence, and energy harvesting, to make bioinspired robots move and sense like animals. In doing so, it makes bioinspired robots an attractive, non-invasive, sustainable, and effective conservation tool for exploration, data collection, intervention, and maintenance tasks. Finally, we discuss the development of bioinspired robots in the context of collaboration, practicality, and applicability that would ensure their further development and widespread use to protect and preserve our natural world.

“…Energy harvesting and storage systems have attracted immense interest due to the increasing energy demand associated with global economic growth. − The depletion of fossil fuels and subsequent rise in energy prices, along with environmental concerns stemming from greenhouse gas emissions from fossil fuels, , make it crucial to decrease carbon emissions and implement sustainable energy storage technologies in electrochemical energy harvesting/storage system applications such as supercapacitors, batteries, and solar cells. − Among them, supercapacitors have the advantages of high power density, high charging rate, and short charging time and are categorized into two classes: electric double-layer capacitors (EDLCs) and pseudocapacitors. The EDLC stores charge by the adsorption of electrolyte ions onto the surface of the electrode material, which does not require a redox reaction.…”

In this study, we report the preparation of a highly conductive metal−organic framework-derived carbon nanocomposite material with excellent electrochemical activity through a simple surface coating of carbonized-ZIF-8 (C-ZIF-8) with poly(3,4-ethylenedioxythiophene)−poly(styrenesulfonate) (PEDOT−PSS). X-ray diffraction results indicate the successful transformation of crystalline ZIF-8 to amorphous carbon (C-ZIF-8) during carbonization at 850 °C. As-prepared C-ZIF-8 and C-ZIF-8/PEDOT−PSS nanocomposites with different weight ratios of 2:1, 8:1, and 14:1 (C-ZIF-8:PEDOT−PSS) were found to have specific surface areas of 920, 450, 740, and 810 m 2 g −1 , respectively. Importantly, the increase in the ratio of PEDOT−PSS (to 2:1) reveals that the PEDOT−PSS seems to block the micro-and mesopores of C-ZIF-8 due to the high density of the PEDOT−PSS coating. In cyclic voltammetry results, the specific capacitances of C-ZIF-8 and C-ZIF-8/PEDOT−PSS (14:1, 8:1, 2:1) at a scan rate of 5 mV S −1 were 44.1, 114.2, 149.4, and 110.3 F g −1 , respectively. The C-ZIF-8/PEDOT−PSS nanocomposite exhibited a 4-fold increase in specific capacitance (77 F g −1 ) compared to that of pristine C-ZIF-8 (18.4 F g −1 ) at a current density of 0.5 A g −1 by galvanostatic charge−discharge. The retention of specific capacitance is maintained over 86% subsequent to 1100 cycles at 2 A g −1 by cyclic stability tests. Furthermore, the specific capacitances of C-ZIF-8/PEDOT−PSS coated on a bendable carbon cloth in its initial state and after the bending cycle test were 208.2 and 186.8 F g −1 , respectively. This indicates that it maintained approximately 90% of its specific capacitance after 1000 bending cycles. Our experiments demonstrate that the C-ZIF-8/PEDOT−PSS nanocomposite exhibits a continuous conductive pathway and electrochemical activity due to PEDOT−PSS along with high porosity, a high specific surface area, abundant electroactive sites, and faster ion diffusion kinetics due to C-ZIF-8.
