미래의 동력이 되다, 우리가 만든 나노소자로.
We are at the forefront of next-generation electronic and energy device research. We specialize in the design of self-powered nanomaterials and energy harvesting devices—ranging from nanogenerators to flexible energy storage solutions—to convert ambient human motion into clean and sustainable energy.
NEEDLAB is a multidisciplinary research group operating at the intersection of materials science, device physics, electrical engineering, and sustainable energy.
Our mission is to design self-powered systems that sense, store, and harvest energy, paving the way toward a more sustainable future.
Novel Electronic & Energy Devices Laboratory, since 2017.
Six interlocking directions — from materials up to systems — unified by one goal: devices that power themselves.
We harvest ambient mechanical energy—from human motion, vibrations, and waves—and convert it into useful electrical power. Furthermore, we design high-efficiency circuitry to optimize the transmission and management of this energy.
High-density, stretchable supercapacitors and batteries for next-generation wearable systems.
Battery-free tactile, motion, and environmental sensors for IoT, healthcare, and soft robotics.
MXenes, 2D materials, and nanostructured electrodes engineered from the atom up.
Skin-conformal electronics and self-charging power units for continuous, untethered operation.
Machine learning to accelerate the design and screening of new energy materials.
