The paper “A biopotential optrode array: operation principles and simulations” by A. Al Abed, H. Srinivas, J. Firth, F. Ladouceur, N.H. Lovell and L. Silvestri, illustrating the concept of using Zedelef’s optical technology to monitor brain activity, has just been published on Nature Publishing Group’s journal “Scientific Reports”. The work presents evidence that optrode arrays based on pixelated liquid crystal cells could dramatically increase the number of sampled electrodes compared to traditional multi electrode array (MEA) technologies.
