Sticker-Like Electronics | Advanced transfer printing technique yields high-performance thin-film electronics on a temporary holding sticker such that the  resulting devices can be pasted onto arbitrary surface or substrate for ubiquitous Internet-of-Things (IoT) sensing applications.

Smart Soft Contact Lenses | All-printed ultrathin soft sensors are integrated with various brands of commercial soft contact lenses without significantly altering the intrinsic lens properties. This technology allows for continuous monitoring of ocular health and diseases in human eyes.

Human Hand-Like Sensory Gloves | Hybrid printing technique enables the integration of stretchable multimodal sensor arrays with nitrile gloves for endowing prosthetic or robotic hands with human hand-like softness, color, texture, and perception.

Personalized Sensor Patches | Mechanically soft and stretchable sensor patch tailored for the submental region of a patient is developed to monitor muscle activities and laryngeal movement for tele-rehabilitation of swallowing disorders.

Custom-Printed Soft Sensors | Direct-ink-writing of bioinks enables the high-throughput batch production of custom-designed soft medical sensors tailored for organs and tissues of particular interests.

Water Strider-Like Sensors | Novel nanofabrication technique is developed to produce a thin and ultra-buoyant sensor that can easily float on the surface of cell culture medium, just like water-strider insects. Envisioned applications of these types of sensors include long-term reliable recording of cellular and tissue functions in real time.

Drug Delivery Platforms | Flexible or dissolvable drug delivery platforms enable minimally-invasive and long-term sustained delivery of therapeutic drugs into the human skin or eye.

Conformable Sensor Arrays | These devices take ultrathin layouts with silicon nanomaterials for highly conformable  sensor arrays that can form intimate, conformal contacts with uneven surfaces of particular interests.

The Lee Research Group focuses on bridging a critical gap between engineering and unmet clinical needs. Our scholarly efforts are dedicated to addressing the gap using novel yet simple microscale transducers with a clear path towards translation to produce measurable clinical and economic impacts. We explore a variety type of wearable biomedical devices, which resemble peel-and-stick stickers. These sticker-like devices are designed to be easily integrated with the human body, enabling the remote monitoring of human health and diseases in a non-invasive, continuous manner. The potential applications of this technology are boundless ranging from home-based telemedicine to on-demand drug delivery systems.
