About

Yeongjae Choi is a rising innovator in the field of soft robotics and microfluidics, with a particular focus on developing simple, accessible fabrication methods for autonomous devices. His most notable contribution is the invention of the "pen-drawn Marangoni swimmer," a concept that reimagines robot construction through the intuitive and creative act of drawing. This work, published in 2023 and already garnering 35 citations, demonstrates how a simple pen can be used to construct swimmers that perform complex, programmed tasks by exploiting the Marangoni effect—a surface tension-driven phenomenon. By replacing traditional, complex manufacturing with a tool as common as a pen, Choi’s research bridges the gap between advanced robotics and everyday creativity, making emergent design and adaptive behavior accessible to a broader audience. His approach not only simplifies prototyping but also opens new avenues for on-demand, deployable micro-robots in environmental monitoring or biomedical applications. Choi’s work stands out for its elegance and practicality, earning him recognition as a key figure in the push toward democratized robotics.
