Abstract Flexible electronics offer a multitude of advantages, such as flexibility, lightweight property, portability, and high durability. These unique properties allow for seamless applications to curved soft surfaces, leading extensive utilization across wide range fields in consumer electronics. applications, example, span integrated circuits, solar cells, batteries, wearable devices, bio-implants, robotics, biomimetic applications. Recently, flexible electronic devices have been...
Numerous wireless optogenetic systems have been reported for practical tether-free optogenetics in freely moving animals. However, most devices rely on battery-powered or coil-powered requiring periodic battery replacement bulky, high-cost charging equipment with delicate antenna design. This leads to spatiotemporal constraints, such as limited experimental duration due life animals' restricted movement within specific areas maintain power transmission. In this study, we present a wireless,...
Understanding brain function is essential for advancing our comprehension of human cognition, behavior, and neurological disorders. Magnetic resonance imaging (MRI) stands out as a powerful tool exploring function, providing detailed insights into its structure physiology. Combining MRI technology with electrophysiological recording system can enhance the functionality through synergistic effects. However, integration neural implants presents challenges because strong electromagnetic (EM)...
Abstract Challenges in the understanding of three-dimensional (3D) brain networks by simultaneously recording both surface and intracortical areas signals remain due to difficulties constructing mechanical design spatial limitations implanted sites.

Abstract Ultrathin crystalline silicon is widely used as an active material for high‐performance, flexible, and stretchable electronics, from simple passive components to complex integrated circuits, due its excellent electrical mechanical properties. However, in contrast conventional wafer‐based devices, ultrathin silicon‐based electronics require expensive rather complicated fabrication process. Although silicon‐on‐insulator (SOI) wafers are commonly obtain a single layer of silicon, they...
Abstract Simultaneous monitoring of electrophysiology and magnetic resonance imaging (MRI) could guide the innovative diagnosis treatment various neurodegenerative diseases that are previously impossible. However, this technique is difficult because existing metal‐based implantable neural interface for not free from signal distortions its intrinsic susceptibility while performing an MRI implanted area interface. Moreover, brain tissue heating implants generated by radiofrequency field poses...
Simultaneous two-photon imaging and electrophysiological recordings offer considerable potential for advancing neurological research therapies. However, traditional metal-based neural interfaces suffer from photoelectric artifacts, while existing transparent implants rely on opaque interconnect lines to address conductivity limitations. Herein, we developed an optically poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) electrode array with electrodes lines. Through a...
Abstract As the biopharmaceutical industry continues to mature in its cost‐effectiveness and productivity, many companies have begun employing larger‐scale biomanufacturing bioprocessing protocols. While of these protocols require cells with anchorage‐independent growth, it remains challenging induce necessary suspension adaptations different cell types. In addition, although transfection efficiency is an important consideration for all cells, especially therapeutic protein production, are...
Here, we present a protocol for the fabrication of transparent implantable electrode arrays integrating optogenetics and electrophysiology. We describe steps fabricating microelectrodes using conductive polymer poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate). then detail procedures analyzing performance electrodes recording light-evoked neural activities from transgenic mouse. This utilizes photolithography rather than conventional electrodeposition. For complete details on use...
