New Type of Flexible Electronics Turns Soft When Implanted Into Body
Electronic devices that become Soft on command*can be extremely useful*for medical implants that would be able to wrap around different types of Body tissues. Surgeons would be able to position the implant while it’s still stiff to let it gently wrap around the target tissue as it becomes soft. Researchers from the University of Texas at Dallas and the University of Tokyo have created mechanically Flexible organic transistors able to do just that.
The investigators used shape-changing memory polymers that respond to the environment around them, staying tough initially at room temperature and becoming softer When warmed up to Body temperature. The wiring within was made of a Flexible foil that conforms to the shape of the device itself. Though they used an organic semiconductor, the scientitsts applied techniques **rmally meant for silicon-based Electronics to build the device, to keep the complexity and cost down. The team tested the tech**logy in the laboratory, successfully wrapping the device around a 2.25 mm wide rod and implanting it Into rats without a loss of electrical properties. In the animal model, the device morphed to the shape of the tissues it found itself pushed around by, demonstrating the real world potential of the tech**logy.
Here’s a video demonstrating the new adaptable Flexible electronic tech**logy:
