A branch of artificial intelligence (AI) and machine learning called deep reinforcement learning (DRL) is concerned with teaching agents to make decisions by interacting with their surroundings. Unlike conventional supervised learning, DRL learns by experimentation rather than labelled datasets. The agent performs activities in the environment and receives feedback through benefits or costs, enabling it to learn the best ways to accomplish particular objectives. DRL has achieved astounding success in several fields, including resource management, robotics, gaming, and autonomous vehicles. Micro-Electro-Mechanical Systems (MEMS) are tiny, integrated systems that incorporate mechanical and electrical elements on a microscopic scale. The tiny mechanical structures, sensors, actuators, and electronics that make up these devices are created using microfabrication. Numerous industries use MEMS technology, including aircraft, biomedicine, consumer electronics, and telecommunications. They have benefits like more diminutive size, less power usage, and better functioning. Nanotechnology, which typically ranges from one to a few hundred nanometers, is the nanoscale's manipulation and engineering of materials and structures. Materials display distinct characteristics and behaviours at this size that are very different from those of their bulk counterparts. Numerous industries use nanotechnology, including nanoelectronics, nanomedicine, environmental cleanup, and energy storage. It can transform several sectors and advance numerous facets of contemporary life (Xian Yeow and Lee et al., 2019).
A well-known subfield of machine learning called Deep Reinforcement Learning (DRL) focuses on teaching intelligent agents how to make decisions by interacting with the outside world. DRL's fundamental ideas revolve around an agent that acts in a given environment and receives feedback through rewards or punishments based on its decisions. The agent can learn and improve its decision-making strategy through this iterative process, maximising cumulative rewards over time. The learner or decision-maker in the DRL system is the agent itself (Kumar Shakya, Pillai, and Chakrabarty, 2023). Other essential elements include the environment in which the agent operates and receives feedback, the actions the agent can take, and the rewards that direct the agent's learning process. DRL has demonstrated outstanding accomplishments in several areas, including the control of complicated games, the ability of robots to learn actions and tasks, the optimisation of autonomous vehicle decision-making, and the improvement of resource management in various industries. Its applications, which range from gaming and entertainment to banking, healthcare, industrial automation, natural language processing, and more, show how adaptable and powerful this cutting-edge method of learning and making decisions is (Kumar Shakya, Pillai, and Chakrabarty, 2023).
Nanotechnology and MEMS (Micro-Electro-Mechanical Systems) are interrelated topics that have transformed numerous businesses and research sectors. MEMS is the microscale integration of minuscule mechanical and electrical parts, typically with sizes between micrometres and millimetres. The manipulation and engineering of materials and structures at the nanoscale, which is typically between one and a few hundred nanometers, are the focus of nanotechnology. The fundamental idea behind MEMS is to create microdevices that can perceive, act, and process information. These gadgets use microfabrication techniques to implement features like pressure, gyro, and accelerometer sensors. In contrast, nanotechnology uses the unique qualities that materials exhibit at the nanoscale to provide new applications in electronics, medicine, energy, and the environment (Kieninger, 2022).
The importance of MEMS and nanotechnology rests in its capacity to support cutting-edge developments in various fields. MEMS sensors and actuators have enabled breakthroughs in mobile devices, wearable technology, and automotive applications, improving user experiences and safety. Nanotechnology has created new opportunities in medicine for tailored medicines, diagnostic tools, and drug delivery systems, all promising to improve patient outcomes. Additionally, nanotechnology has aided in developing environmentally friendly cleaning agents, renewable energy sources, and energy-efficient materials (Kieninger 2022).
Despite their achievements, MEMS and nanotechnology still have problems that could use Deep Reinforcement Learning (DRL) solutions. These industries entail intricate manufacturing procedures, control systems, and design optimisation. In order to automate the design of MEMS devices and nanoscale structures and maximise their performance considering various constraints, DRL could play a vital role. DRL may also help streamline production procedures, lower faults, and raise yields. Additionally, DRL can be used in research fields to optimise experimental settings for creating nanoscale materials and structures, producing more effective and affordable research results. By addressing these issues, using DRL, MEMS and nanotechnology can advance even more quickly and open up new opportunities for various applications (Kieninger 2022).
It is possible to revolutionise different facets of design, manufacturing, and control processes in these sectors by combining Deep Reinforcement Learning (DRL) and MEMS/nanotechnology. Numerous benefits can be gained by utilising DRL to overcome the difficulties experienced in MEMS and nanotechnology applications. First, by using autonomous agents to explore and pinpoint ideal configurations in the vast design space, DRL may considerably improve the design process, creating highly effective and high-performance MEMS devices and nanoscale structures. Second, by continuously learning from real-time data, DRL can increase process efficiency in manufacturing. This enables adaptive control of fabrication processes, which lowers errors and increases yield rates. Additionally, using DRL's self-learning capabilities, complex MEMS and nanoscale systems can be controlled precisely and steadily while overcoming nonlinear dynamics and uncertainty problems (Totsu, Moriyama, and Esashi 2019).
The prospective results of merging DRL and MEMS/nanotechnology are demonstrated by existing research. Notably, DRL has been utilised to optimise resonator shapes in MEMS device design, improving resonance frequencies and quality factors. Similarly, controlled manufacturing of nanoparticles and nanowires with desired material properties has been made possible in nanomaterial synthesis by DRL-driven optimisation. Furthermore, using DRL in nanorobotics has opened the door for accurate assembly and manipulation at the nanoscale, promising significant advances in nanotechnology. Researchers and engineers may unlock new levels of innovation and efficiency by incorporating DRL into MEMS and nanotechnology, launching these sciences into a new era of transformational applications across electronics, healthcare, energy, and beyond. The dynamic synergy between DRL and MEMS/nanotechnology can create a world in which complex micro- and nanoscale systems are used daily to solve challenging challenges and push the limits of technological advancement (Totsu, Moriyama, and Esashi 2019).
Deep Reinforcement Learning (DRL) applications have shown considerable potential in improving the functionality, performance, and efficiency of these micro- and nanoscale systems. DRL's capacity to streamline design, manufacturing, and control procedures has sparked ground-breaking developments across various applications. This section will concentrate on specific DRL applications in MEMS and nanoscale systems, examine how DRL enhances functionality, and offer practical DRL implementations (Kumar et al. 2019).
These illustrations show how DRL can improve MEMS and nanotechnology systems' functionality, performance, and efficiency. These applications attain higher levels of precision, lessen the need for human involvement, and increase process control by utilising DRL's self-learning capabilities. Additionally, DRL-driven optimisation makes it possible to explore design spaces that conventional approaches might not have been able to explore due to computational limitations. Overall, DRL has shown that it can revolutionise MEMS and nanotechnology. We may anticipate more developments in these areas as DRL research and development expand. These discoveries will influence the direction of micro- and nanoscale systems and propel applications in electronics, healthcare, energy, and other domains (Kumar et al. 2019).
Several issues hamper DRL integration in MEMS and nanotechnology. Real-time applications in nanoscale systems may need to be improved by the computational complexity of DRL methods. Additionally, particularly in nanotechnology trials, acquiring data for training DRL agents can be time-consuming and expensive. Due to the possibility that DRL agents could explore unexplored areas of the design space and provide subpar or harmful results, safety and dependability issues are raised. Despite these obstacles, ongoing research strives to create more effective DRL algorithms targeted to micro- and nanoscale applications, overcome data scarcity through transfer learning, and implement safety measures to assure robust and dependable performance in real-world circumstances (Khaksar 2019).
The potential for DRL breakthroughs and new applications in MEMS and nanotechnology is quite promising. Incorporating DRL with multi-agent systems is one path that could be taken to enable cooperative decision-making in challenging nanorobotic assembly and manufacturing processes. Furthermore, integrating DRL with sophisticated sensing and imaging techniques may improve real-time feedback, enabling more accurate control and optimisation. Research efforts will concentrate on creating more effective and scalable algorithms suitable for resource-constrained nanoscale systems as DRL algorithms advance. Exploring unsupervised and self-supervised learning techniques may also open up new opportunities for autonomous MEMS and nanotechnology discovery and optimisation, opening the path for ground-breaking innovations (Kieninger 2022).
The use of DRL in MEMS and nanotechnology presents moral questions. Responsible AI deployment is essential to avoid unforeseen outcomes like biased decision-making and potential threats to human health and the environment. AI-driven nanosystems' potential effects on society must be carefully considered, considering factors like job displacement, data security, and privacy. Guidelines should emphasise open decision-making procedures, thorough testing and validation of DRL algorithms, and adherence to safety regulations to ensure ethical and secure adoption. Collaboration is necessary between researchers, policymakers, and industrial players to build ethical solid frameworks that prioritise human well-being and solve the difficulties of adopting DRL in these delicate domains (Totsu, Moriyama, and Esashi 2019).

It improves performance and efficiency in various applications by enabling precise manipulation, autonomous production, and innovative material synthesis. However, issues including computing complexity, data scarcity, and ethical considerations must be addressed for responsible adoption. Despite these obstacles, DRL holds enormous potential for these industries, providing game-changing solutions for everything from electronics to healthcare.
