Optogenetics is a powerful tool for controlling biological functions using light. Optical fibers have been extensively utilized in optical stimulation devices for optogenetics. However, the use of optical fibers results in a small photo-stimulation r

In this study, we propose a complementary-metal-oxide-semiconductor (CMOS) image sensor with a self-resetting system demonstrating a high signal-to-noise ratio (SNR) to detect small intrinsic signals such as a hemodynamic reaction or neural activity

In neuroscience, it is crucial to clarify the relationship between single-cell activity and neural network structure to understand brain neural activity. To this end, a device that can measure signals with high temporal resolution over a wide area is

We propose an ultra-compact lensless CMOS image sensor that comprises angle-selective pixels and normal pixels. We have demonstrated that the image resolution can be recovered from blurred images by combining this sensor with image processing.

Angle-selective pixels fabricated by using metal layers of the image sensor chip are proposed. Four incident-angle-selective pixels share one aperture. The selective pixel has a peak at 40° and full width at half maximum of ∼23°. An image sensor

Since device performance is greatly influenced by minute variations in the crystal structure of its constituent materials, reliably predicting the lattice parameters of perovskites can aid in minimizing structural mismatch and improve film integrity.
