Накратко на български

Микророботи, задвижвани от ултразвук и вдъхновени от микроорганизмите, се разработват за самостоятелно движение в сложни среди. Това ще помогне за по-прецизно доставяне на лекарства в тялото или за по-добро наблюдение на околната среда.

Intelligent MIcrorobot POweRed by Ultrasound

Over the past decade, microrobots have showcased immense potential, from precise drug delivery to minimally invasive surgeries. However, existing models lack self-navigation abilities, limiting their practical application. The aim is to engineer a microrobot energized by ultrasound capable of independent movement within complex environments, a feat unattained until now. One of the challenges lies in miniaturization; traditional robotic components cannot be shrunk to microscale dimensions. Therefore, inspiration is drawn from microorganisms, replicating their design principles to instill autonomy in these micromachines. An additional challenge is propulsion on the microscale. Ultrasound emerges as a promising avenue for propulsion and motion control due to its non-destructive and tissue-penetrating capabilities. By utilizing acoustic streaming (mean flow of fluid), generated by vibrating microstructures or gas bubbles, and additional nonlinear acoustic phenomena we aim to achieve precise, efficient microrobot propulsion. The microrobot's ultimate goal is Taxis behavior - the ability to respond to external cues like chemicals or temperature gradients. This opens doors for targeted medical applications or environmental monitoring. Our approach spans diverse disciplines - robotics, additive manufacturing, fluid dynamics, and materials science. With a focus on predictive modeling, experimental validation, and manufacturing techniques, this research aims to revolutionize microrobotics, appealing to both academia and industry. This venture strives for excellence in microrobotics, aiming to create a pioneering autonomous microrobot driven by ultrasound, which could revolutionize healthcare and environmental monitoring through its advanced navigation abilities and responsiveness to external stimuli.

Цел на проекта

Microrobots with the ability of sensing physiologically important signals and respond by autonomously accumulating at target sites may revolutionize minimally invasive medicine. Miniaturizing electronic sensors, actuators and batteries to microscale is not feasible with the state-of-the-art technology. A promising alternative for instantiating on-board sensing and computation for remotely powered micromachines is exploiting structure and material properties. Recent studies show that micromachines can transform acoustic waves into controllable motion and powering can be realized using off-the-shelf medical ultrasound transducers. The objective of IMIPORU project is to develop the first truly autonomous microrobots powered by acoustic streaming (acoustically generated steady flow) that can perform taxis behaviour. To achieve this task, I will systematically study fluid-structure interaction (FSI) at the microscale numerically, experimentally and analytically. This analysis will lead to the design of novel mechanisms that respond to varying hydrodynamic loads. By manifesting mechanical instabilities, robots will mimic flagellated bacteria that exploits the buckling of the hook to change direction. Furthermore, understanding FSI is instrumental for optimizing the acoustic propulsion machinery. State-of-the-art, high-resolution two-photon polymerization technique for photocurable polymers will be used to manufacture multi-material structures with complex geometries. Since acoustic actuation does not depend on material choice, integrating responsive soft hydrogels into the structure will add another dimension for interacting with the environmental via chemical and temperature signals. Incorporating intelligent mechanical design along with responsive materials will enable microrobots to change their form and kinematics in different viscosity, temperature or chemical conditions, paving the way to autonomous navigation including viscotaxis, chemotaxis, and thermotaxis
