Section Information

“Physics of Micromachines” centers on the scientific principles, physical mechanisms, and design strategies that govern micro/nanoscale systems, emphasizing fundamental multiphysics phenomena—including solid mechanics, electrostatics/electrodynamics, thermofluidics, heat and mass transport, and quantum- and plasmonic-scale effects—underpinning devices and architectures across Nano/Microelectromechanical Systems (N/MEMSs). We seek contributions that elucidate core research themes such as transduction physics for mechanical and electrical sensors and actuators; optical and optoelectronic phenomena (including plasmonic and metal-based photonics); micro/nanoscale energy conversion and storage; and the material behavior and interfacial science enabling flexible, stretchable, and wearable electronics/sensors, as well as the locomotion, control, and collective dynamics of microbots (including swarm robotics), nanorobots, and micro air vehicles. By connecting fundamental insights to application pathways, this section highlights advances that impact precision sensing, ultra-low-power computation, biomedical diagnostics and therapeutics, environmental monitoring, and autonomous micromobility—framing how physical understanding accelerates translational technologies and informs future, scalable manufacturing. We welcome methodological advances spanning micro/nanofabrication and additive/lithographic processing, in situ and operando characterization, high-fidelity multiphysics modeling and multiscale simulation, uncertainty quantification and reliability analysis, and physics-informed optimization and control for device and system design. Looking ahead, we particularly encourage work on emerging materials (e.g., 2D, ferroelectric, piezo/tribo/pyro-active composites), novel energy-harvesting nanogenerators, soft and biohybrid microrobotics, inverse-design and machine learning-guided discovery, and the physics of collective and adaptive behaviors—especially where key knowledge gaps (scaling limits, nonlinear coupling, stability, aging, and variability) are rigorously addressed. This section accepts original research articles, short communications/technical notes, methods papers, reviews, and perspectives, and strongly supports interdisciplinary collaborations bridging physics, materials science, electrical/mechanical engineering, chemistry, photonics, and biomedicine. Our overarching goal is to advance foundational understanding that enables robust, optimized, and integrable micromachines, catalyzing innovation from physical theory to impactful technologies.
