Functional Bio-integrated Electronics research team have developed a passive, bioresorbable electrode array with an ultra-thin Si encapsulation barrier. In vivo neural recordings with the bioresorbable neural sensors in adult rat animal models showed good performance associated with both action potentials and local field potentials. This particular device functions for a programmed time period and slowly dissolves in the body over time such that the secondary surgery to extract the device is not required. The National Research Foundation supported this research. The new results are published in the journal of ACS Nano.
