The increasing demand for efficient and reliable gas sensors has propelled the exploration of novel materials and advanced simulation techniques. This study presents the design and development of a gas sensor that detects acetone using molybdenum disulfide $(\mathbf{MoS}_sensor)$ as the sensing material. Acetone is a major volatile organic compound that has applications in a variety of industries, including healthcare and environmental monitoring. Acetone gas is a respiratory symptom that indicates diabetes. The high sensitivity, stability and cost of $\mathbf{MoS}_{\mathbfsensor}$ make it a good sensor material. The sensor design involves the integration of $\mathbf{MoS}_{\mathbfsensor}$ thin films onto a substrate, with interdigitated electrodes facilitating the detection mechanism. COMSOL Multiphysics, a versatile simulation software, is employed to model the sensor's performance under different operating conditions and geometrical configurations. The simulation framework incorporates electrochemical processes, mass transport phenomena, and electrical properties to accurately represent the sensor's *** was found that the resistance of the sensor layer was reduced in the presence of acetone gas. The simulation was carried out using COMSOL Multiphysics.

Deep Reinforcement Learning (DRL) faces challenges bridging the sim-to-real gap to enable real-world applications. In contrast to the simulated environments used in conventional DRL training, real-world systems are non-linear and evolve in an asynchronous fashion;sensors and actuators have limited precision;communication channels are noisy;and many components introduce variable delays. While these issues are known to many researchers, published methods for systematically tackling the problem of DRL training under these conditions without using simulation are sparse in the field. To this end, this paper proposes a non-blocking and asynchronous DRL training architecture for non-linear, real-time dynamical systems tailored to handling variable delays. Compared to conventional DRL training, we: (i) decouple the RL loop into separate processes run independently at their own frequencies, (ii) further decouple collection of transition tuples (s(t);at(t);s(t+1)) via asynchronous and independent streaming of both actions and observations, and (iii) mitigate the effects of delays and increase sample efficiency by providing delay-length measurements to the training loop and regular retraining of the DRL network. This allows the action step time to be tuned to find an optimal control frequency for a given system, and handles streamed observations that arrive with random delays and independently of action timing. We demonstrate the efficacy of this architecture with a physical implementations of a commodity-grade swing-up pendulum and a quadrupedal robot. Our architecture achieves the best results balancing the pendulum for almost entire length of the episode, compared to conventional blocking approaches which fail to learn effective policies. Our results show that these techniques scale to more complex tasks such as quadrupedal locomotion.
