3D Printed Flexible and Stretchable Tissue-Like Electronic Devices for Neural Recording

The utilization of neural recording technology has significantly transformed our comprehension of the brain, spinal cord, and other nervous systems. These technologies have provided essential insights into neural activity, hence facilitating the development of groundbreaking therapeutic approaches. Nevertheless, the development of neural recording devices that can match the properties of neural tissues remains a significant challenge. Furthermore, commonly used neural recording devices are usually time-consuming to fabricate and costly. This research presents a novel strategy to tackle the aforementioned obstacle, wherein we propose the utilization of 3D printable flexible and stretchable tissue-like electronic devices for the purpose of neural recording. The device exhibits a unique structure that offers remarkable characteristics like flexibility, stretchability, and conformability. These properties facilitate the seamless integration of the device with the brain and spinal cord. In addition, the 3D printing manufacturing process can allow rapid fabrication of designed neural electronic devices and is less costly than lithography-based manufacturing methods. This innovation exhibits remarkable ramifications, presenting significant prospects for the fields of brain-computer interfaces, neuromodulation, and neural prosthetics.
