PLCL from PolySciTech used in development of Neural Interface system

 

Developing the ability to interface between brain signals and digital equipment can be highly useful for patients suffering from paralysis or other disease states limiting their bodily mobility. Researchers at Seoul National University, Dankook University, University of Ulsan, Kwangwoon University, Korea University, Northwestern University, Gyeongsang National University, Sungkyunkwan University used PLCL (AP067) from PolySciTech Division of Akina, Inc. (www.polyscitech.com) to create a biocompatible and flexible structure for minimally invasive implantation of a neural interface. This research holds promise to provide for improved prosthetics and other human-digital interfaces in the future.

“High-density, large-area electronic interfaces are a key component of brain–computer interface technologies. However, current designs typically require patients to undergo invasive procedures, which can lead to various complications. Here, we report a biodegradable and self-deployable tent electrode for brain cortex interfacing. The system can be integrated with multiplexing arrays and a wireless module for near-field communication and data transfer. It can be programmably packaged and self-deployed using a syringe for minimally invasive delivery through a small hole. Following delivery, it can expand to cover an area around 200 times its initial size. The electrode also naturally decomposes within the body after use, minimizing the impact of subsequent removal surgery. Through in vivo demonstrations, we show that our cortical-interfacing platform can be used to stimulate large populations of cortical activities.”
