Buckling‐Resistant and Trace‐Stacked (BRATS) Design Enables Aid‐Free Implantation of Flexible Multielectrode Array with Minimized Inflammatory Tissue Response

Advanced Functional Materials, EarlyView.
Buckling‐resistant and trace‐stacked (BRATS) intracortical microelectrode arrays (MEAs) eliminate the need for insertion aid and complex surgical setup, resulting in minimal inflammatory tissue response, compared to conventional flexible MEAs inserted with aid. Trace stacking effectively doubled the channel count without increasing the MEA shank width,

High‐Spatiotemporal‐Resolution Transparent Thermoelectric Temperature Sensor Arrays Reveal Temperature‐Dependent Windows for Reversible Photothermal Neuromodulation

Advanced Functional Materials, EarlyView.
Thermoelectric temperature sensors are developed that directly measure heat changes during optical‐based neural stimulation with millisecond precision. The sensors reveal the temperature windows for safe reversible neural modulation: 1.4–4.5 °C enables reversible neural inhibition, while temperatures above 6.1 °C cause permanent thermal damage.
