Development of ultra-thin implantable materials keeping stability and functionality inside the human body
- Expecting for the treat of injuries to the spinal cord and Parkinson’s disease -
Yusuke Yamauchi, MANA Principal Investigator of Mesoscale Materials Chemistry Group and international collaborative team of Griffith University, University of Southern Queensland, The University of New South Wales, The University of Queensland, in Australia, and JST-ERATO Project in Japan succeeded in developing an implantable and flexible electronic system as a new platform for long-term bio tissue interface.
Implantable electronic devices were expected to be a tool in the treatment of spinal injuries, Parkinson’s disease and so on, but conventional materials have problems with flexibility, heat resistance, impact resistance, and chemical stability.
To solve these problems, the research team developed flexible wide bandage materials with silicon carbide (SiC) as the contact surface and silicon dioxide as the protective encapsulation and found that the device keeps its functional stability even in a bio tissue.
This implantable and flexible electronic system will provide promising avenues for future neuroscience and neural therapies, which could offer live-saving treatments for chronic neurological diseases and stimulate patient recovery.
