Changsheng WU

Dr. Changsheng WU obtained his Bachelor in Engineering Science from NUS and PhD in Materials Science and Engineering from Georgia Tech, with his thesis focusing on nanogenerator-based electromechanical systems for energy harvesting and sensing. He carried out postdoctoral research in the Querrey Simpson Institute for Bioelectronics at Northwestern University (US), where he developed wireless wearable biosensors for clinical-grade health monitoring and 3D multi-scale metastructures for soft skin-electronics interface. He has published more than 50 papers and holds 5 patents. His works have won awards including the TechConnect 2018 Innovation Award and the 56th R&D 100 Award.  

Research Interests

The rapid pace of population ageing and the global outbreak of pandemics have highlighted the deficiency of medical resources and inefficiency of health systems, thus calling for imminent advancement of biomedical technologies. The Wu group focus on developing wireless wearables and intelligent robots for energy harvesting, biosensing and therapeutic applications, leveraging bioelectronics, materials science, and advanced manufacturing to create continuous, pervasive, and personalized digital health solutions. The research areas we are interested in include: 

Bioelectronics  

• Wireless soft devices for health monitoring or therapy 
• Advanced signal processing and analysis of bio-signals  
• Closed-loop sensing & therapeutic systems  

Electromechanical Systems  

• Triboelectric nanogenerator (TENG) & piezoelectric nanogenerator (PENG)  
• Biomechanical energy harvesters and sensors 
• Self-powered biosensing systems  

3D Multiscale Structures for Soft Tissue-Electronics Interface 

• Novel metastructures for soft biosensors and energy harvesters  
• Programmable metamaterials for actuation and sensing 
• Wirelessly controllable and reconfigurable soft robots
