Nanosensors, and Micromachines

What We Do

Our research goes beyond simple sensing elements to engineer fully integrated nanoscale devices capable of complex tasks. We design self-powered, wireless microsystems that harvest ambient energy sources (e.g., radio frequency signals) to operate without traditional batteries. Simultaneously, we create micromachines and microrobots—tiny mechanical devices that can move, sense, and even interact with their environment at microscale resolutions. These micro- robots might assemble intricate microcomponents for specialized electronics, navigate fluid channels to deliver targeted therapeutics, or monitor subtle environmental changes. By combining nanomanufacturing techniques, advanced lithography, and finely tuned material interfaces, we tailor structures that can withstand fluidic shear forces, chemical exposures, and mechanical stresses, all while performing highly specialized functions.

Why It Matters

From medical applications—where microrobots could one day transport drugs directly to diseased cells—to precision manufacturing, where these devices might assist in building next- generation microchips or advanced sensors, nanoscale robotic systems hold tremendous promise. They represent a leap forward in how we interact with and control processes at the smallest scales, laying the groundwork for smarter, more responsive technologies that function in spaces too small or delicate for conventional machinery.

A Closer Look (For the Curious)

Realizing these tiny machines involves multi-step fabrication processes, including photolithography, soft lithography, focused ion beam structuring, and advanced surface treatments that promote desired interactions at the nanoscale. We integrate stimuli-responsive materials that change shape or properties under heat, light, magnetic fields, or chemical gradients. The complexity lies not only in making these microrobots but ensuring they remain functional, reliable, and safe in dynamically changing environments.
