Micro- and Nano-Materials/Generators for Bioelectrical Stimulation Applications
We develop advanced micro- and nano-structured materials and energy-harvesting generators capable of converting biomechanical and biothermal energy into controllable electrical stimuli for biomedical applications. By harnessing triboelectric, piezoelectric, and thermoelectric principles, we engineer high-performance nanomaterials and self-powered generators that modulate cellular behavior and support therapeutic interventions such as wound healing, neural repair, tissue regeneration, and rehabilitation. Our research emphasizes rational structural design, interface engineering, and material optimization to enhance electrical output, ensure long-term stability, and improve biocompatibility. Through these efforts, we aim to establish next-generation bioelectrical stimulation platforms that enable safe, efficient, and clinically translatable therapies.
Self-Powered (Bio)Chemical Sensors
Our lab focuses on designing self-powered chemical and biosensing platforms that autonomously harvest mechanical or thermal energy to operate without external power. By exploiting triboelectric and thermoelectric effects, we create ultra-sensitive sensors for real-time detection of chemical analytes and biomarkers. These autonomous sensing systems have applications in environmental monitoring, healthcare diagnostics, and wearable interfaces for continuous health tracking.
Biomedical Diagnostic Devices
We engineer innovative biomedical diagnostic devices that provide rapid, accurate, and minimally invasive health assessment. By integrating advanced materials, sensing technologies, and intelligent signal processing, our devices aim to improve disease detection, patient monitoring, and clinical decision-making.
Wearable Healthcare Electronics and Remote Intelligent Monitoring Platforms
We develop wearable healthcare electronics and remote monitoring systems capable of continuously tracking physiological signals in daily life. Through seamless integration of flexible sensors, wireless communication, and AI-based analytics, our platforms enable personalized health management and smart telemedicine applications.
Non-Photoactive Nanocatalysts for Disinfection and Biomedical Applications
The highly reactive nature of reactive oxygen species (ROS) is the basis for widespread use in healthcare and biomedical research fields. Conventionally, there is only one kind of catalysts used for ROS generation: photocatalysts (like TiO2). However, its usage has been limited due to various environmental and physical factors. To address this problem, Dr. Lin’s group reported triboelectric (like PTFE), piezoelectric (like MoS2) and thermoelectric (like Bi2Te3, Sb2Te3 and PbTe) materials as piezocatalysts and thermocatalysts which can produce ROS (like ·OH, ·O2- or H2O2) under a vibration or surrounding temperature difference, respectively. Being prevalent environmental factors in daily life, related mechanical stimuli and thermal effects have tremendous potential for practical applications. Vibration triggered ·OH/·O2- formation by piezocatalysts or temperature difference induced H2O2 generation by thermocatalysts results in the effectively oxidative damage of bacteria, which makes both of them highly promising for real-time disinfection applications. As a whole, the concepts presented here highly promote the merits of piezocatalysts and thermocatalysts for round-the-clock ROS generation that can open a new direction towards sustainable environmental remediation and biomedical applications.
