In this review, the concept, design, performance, and a functional demonstration of multifunctional complementary metal-oxide-semiconductor (CMOS) image sensors dedicated to on-chip biosensing applications are described. We developed a sensor architecture that allows flexible configuration of a sensing pixel array consisting of optical and electric sensing pixels, and designed multifunctional CMOS image sensors that can sense light intensity and electric potential or apply a voltage to an on-chip measurement target. We describe the sensors' architecture on the basis of the type of electric measurement or imaging functionalities.

In this study, we describe a low-noise complementary metal-oxide semiconductor (CMOS) image sensor (CIS) with a 10/11-bit hybrid single-slope analog-to-digital converter (SS-ADC). The proposed hybrid SS-ADC provides a resolution of 11 bits in low-light and 10 bits in high-light. To this end, in the low-light section, the digital-correlated double sampling method using a double data rate structure was used to obtain a noise performance similar to that of the 11-bit SS-ADC under low-light conditions, while maintaining linear in-out characteristics.

Optical neural networks are considered next-generation physical implementations of artificial neural networks, but their capabilities are limited by on-chip integration scale and requirement for coherent light sources. This study proposes a spectral convolutional neural network (SCNN) with matter meta-imaging. The optical convolutional layer is implemented by integrating very large-scale and pixel-aligned spectral filters on CMOS image sensor.

Nocturnal and crepuscular fast-eyed insects often exploit multiple optical channels and temporal summation for fast and low-light imaging. Here, we report high-speed and high-sensitive microlens array camera (HS-MAC), inspired by multiple optical channels and temporal summation for insect vision. HS-MAC features cross-talk-free offset microlens arrays on a single rolling shutter CMOS image sensor and performs high-speed and high-sensitivity imaging by using channel fragmentation, temporal summation, and compressive frame reconstruction.

Comparison of radiographic imaging quality/accuracy using photostimulable phosphor plates and metal oxide semiconductor receptors.

J Dent Educ

December 2024

Instituto de Odontoestomatología, Escuela de Odontología, Facultad de Medicina, Universidad Austral de Chile, Valdivia, Chile.

Aim: To compare thequality and accuracy of radiographic images obtained by dentistry students from a Chilean university using photostimulable phosphor plates (PSP) and complementary metal oxide semiconductor (CMOS) receptors.

Materials And Methods: An experimental study was carried out in which 31 dental students used PSP and CMOS receptors to acquire radiographic images with the aid of a phantom. The time required to generate a radiograph was recorded.

Article Synopsis
  • Hyperspectral imaging (HSI) combined with machine learning (ML) offers a promising method for evaluating the freshness of meat by measuring fluorescence, which is closely linked to bacterial density.
  • The study introduces a freshness index (FI) as a quantifiable metric for meat freshness, enabling the processing of hyperspectral data to estimate freshness even in unknown states.
  • This technology could revolutionize consumer electronics, enhancing devices like refrigerators and smartphones with advanced sensing capabilities for more personalized user experiences.
