Lab Overview
1. Multi-dimensional Biodegradable Electronics for Minimally Invasive Implantation
How can biomedical devices and instruments be designed to safely disappear after fulfilling their medical purpose? Eliminating the need for secondary surgery not only reduces the risks of infection and hemorrhage but also lowers healthcare costs and improves patient experience. Our research focuses on the development of fully biodegradable and resorbable medical implants, integrating advanced materials and bioelectronics to ensure minimal invasiveness and optimal functionality. We explore the mechanisms of bioresorption in electronics, the hybridization of soft organic substrates with inorganic electronics, and the application of these materials in biological systems.
2. Zero-Waste/Eco-Friendly Electronic Materials
The rapid advancement of electronic devices has led to significant environmental concerns regarding electronic waste and resource consumption. Our research focuses on the development of biodegradable and sustainable electronic materials that minimize waste generation while maintaining high-performance functionality. We explore environmentally friendly energy harvesting technologies, including triboelectric, thermoelectric, and solar cells, to integrate self-sustaining electronics into a circular economy model.
3. Hardware-Security Materials
With the increasing adoption of automation, AI-driven systems, and unmanned technologies, the security of electronic hardware has become a critical concern. Our research aims to develop self-destructing materials capable of protecting sensitive data and preventing unauthorized access in high-risk environments. We focus on trigger-based self-destructing materials activated by external stimuli such as UV light and heat, ensuring controlled disintegration at the desired moment.
4. Reliability of Structural Nanomaterials and Safety Diagnosis Technology
Ensuring the long-term reliability and stability of advanced electronic and structural materials is crucial for both biomedical and industrial applications. Our research investigates the degradation mechanisms of nanomaterials, focusing on their mechanical integrity, environmental resistance, and failure prediction methodologies. We develop advanced monitoring systems capable of real-time diagnostics and preventive maintenance to enhance safety and extend the lifespan of critical infrastructure.
Through these four core research areas, our lab is pioneering the next generation of biodegradable, sustainable, and reliable electronic materials, contributing to technological advancements in medical, environmental, and security applications.

Lab Overview
1. Biodegradable, minimally invasive implants
What happens if biomedical device and instruments are absorbed into the body after medical treatment? This eliminates the need for risky secondary surgery, which can potentially cause infection and hemorrhage, reduces patient cost and time, and improves the patient experience. Biodegradable, minimally invasive implants perform a series of research in design and fabrication of biomedical devices with fully biodegradable and resorbable materials, and in demonstrations in biological systems. The specific areas are understanding the mechanism of bioresorption of electronics, hybridizing soft substrate to inorganic electronics, and applying the developed electronics to demonstration biological systems.
2. Soft and conformal biomedical devices
How can medical services change by biomedical devices that can be integrated on or in the body? Here we highlight wearable/implantable bioelectronic devices that are soft, flexible and elastic so that they can be interfaced to tissue. This type of device let us perform biomedical diagnosis and treatment in a personal, mobile and real-time manner. Hybrids of inorganic electronic and soft organic substrates can provide high-performance electronics with flexible/conformal interfaces. We design various types of sensors such as body temperature, intra-cavity pressure, humidity, thermodiffusion, flow rate sensors to pH, glucose, and other biochemical sensors. This work also includes research on mechanical understanding on the deformation and human movement, and on fabrication methodologies for biomedical electronics.
3. Biomedical reliability of electronics
Malfunctions of biomedical devices are extremely critical in patient diagnosis and treatment, and thus the reliability of bioelectronics play an important role during the translational and commercialization stage of newly developed techniques. Biofluid, a mixture of various elements induces electrochemical reactions and the movement and metabolism of organ systems cause mechanical degradation. Biological immune reactions to foreign bodies must be considered for realization of medical tools. This topic covers understanding and evaluating the various factors that determine the lifetime and stability of implanted devices and providing methodologies to ameliorate reliability problems.
