Printing Thin Film Electronics on Arbitrary Surface
Sticker-like sensors | Advanced transfer printing technique yields high-performance thin film nanosensors on a temporary holding sticker such that the devices can be pasted onto arbitrary surface or substrate for ubiquitous Internet-of-Things (IoT) sensing applications.
Conformal Nanosensors | These devices use silicon nanomateirals and ultrathin layouts to serve as active semiconducting elements and device platforms, respectively. The result is an highly sensitive soft nanoelectronics that enable to form intimate, conformal contacts with uneven surface of fingertip as an example.
Skin-like Wearable Devices | This advanced multifunctional device involves a stretchable electronic system that is equipped with tri-axis accelerometers, temperature sensors, a Bluetooth low-energy communication system and a battery, all connected in a format of islands/serpentine interconnectors. Incorporation of human skin-like colors, textures, and other features modulate the physical appearance and aesthetics of the entire system.
Water strider-like Sensors | Novel nanofabrication technique allows to create an ultrathin, ultralight and waterproof sensor that can easily float on the surface of water, just like water-strider insects. Envisioned applications of these types of ‘water strider-like electronics’ include environmental monitors for pollutants on lake and river through the years.
Three-Dimensional (3D) Nanoelectronics | Advanced nano-engineering techniques allow to build conformable nanoelectronics that can integrate with 3D surfaces of arbitrary. The results present a novel class of biomedical sensors and stimulators that enable to efficiently access to the biology from multi-dimensional perspectives.
Paper Solar Cells | Realization of novel nanomanufacturing technique yields paper-based solar cells in layouts that place functional hydrogenated amorphous silicon thin film solar cells on a sheet of paper, represented by the World cheapest and lightest substrates. This approach provide a general route to reduce cost and weight of thin film electronics.
Bioresorbable Electronics | Advanced process for bioresorbable materials yields the highly functional integrated system that consists of thermal actuators, lipid membranes and wireless power supplies that can completely dissolve in physiological conditions. The result is an implantable drug delivery vehicle that is capable of releasing drugs on-demand in a controlled fashion and disappearing in the body after the mission is completed.
The Lee Research Group focuses on the development of scalable nanomanufacturing technology that enables the production of various kinds of wearable bio-electronics. The plural developing devices in the group include various skin-mountable biomedical sensors, eye-wearable healthcare systems, bio-integrated nano-electronics, reconfigurable three-dimensional bio-electronics, and miniaturized wireless wearables for small animals. These efforts are also dedicated to exploring fundamental studies at the unique interface between the mechanically soft electronics and biology from highly multidisciplinary perspective. We envision these innovative researches that will serve our society with new technologies.
