    Bistable liquid crystal (LC) shutters have attracted much interest due to their low energy consumption and fast response time. In this paper, we demonstrate an electrically tunable/switchable biostable LC light shutter in biological optics through a three–step easy–assembly, inexpensive, multi–channel shutter. The liquid crystal exhibits tunable transparency (100% to 10% compared to the initial light intensity) under different voltages (0 V to 90 V), indicating its tunable potential. By using biomedical images, the response time, resolution, and light intensity changes of the LC under different voltages in three common fluorescence wavelengths are displayed intuitively. Particularly, the shutter’s performance in tumor images under the near–infrared band shows its application potential in biomedical imaging fields.

    In this study, a thin-film, three-dimensional (3D) opto-electro array with 4 addressable microscale light-emitting diodes for surface illumination of dorsal root ganglions (DRGs) and 9 penetrating electrodes for simultaneous recordings of light-evoked DRG activities is described for Developing a tool to better understand the relationship between spindle length-sensitive afferents from hip muscles and both interlimb coordination and gait selection. Importantly, using the origami design concept, the array can be fabricated directly on a silicon wafer in a two-dimensional (2D) configuration, which can transform into a 3D structure by folding.
