An international research team has succeeded in manufacturing the world’s first flexible, organic transistor that will help make patient monitoring devices easier to implant and integrate with the human body, and is expected to be adopted into wearable, patch-like health monitors or implantable devices like pace makers.
Up until now, existing organic transistors had huge obstacles towards their practical usage in the health and medical field because they are not durable under high temperature sterilization. The newly developed organic transistors are capable of being sterilized under high temperatures without electrically deteriorating–almost all the bacteria died off, but the electrical characteristics of the organic transistor were left unchanged.
The innovation has far-reaching implications. The transistor can easily be manufactured and broadens the usage of the organic transistors as medical devices due to its flexibility and ability to cover large areas. Potential applications offered by the biocompatible transistors include wearable electronics that read bio-information from outside the skin, or implantable electronics that directly extract health information from the body. The invention also opens a new path to the development of thin film sensors which detect tumors, inflammations, and early cancers.
Since flexibility, large coverage, and electric stability are indispensable for implementation of these medical devices, the present invention is expected to serve as the core technology when developing the future medical devices.
