    Flexible neural devices is very useful since they can be conformally placed on brain and rolled upon the spine to control the movement or even treat various diseases. This technology could be utilized in the large animal body for simultaneous sensing and controlling of neural optogenetic signals. We have developed unique microLED based flexible electrocorticogram (ECoG) system for neural interactions.
