In the past few years, a tremendous advancement in the outcome of biomedical circuits and systems has been reported. Unfortunately, at the time of the sudden outbreak of COVID-19, the electronic engineering researchers felt dearth on their side to combat the pandemic, as no such immediate cutting-edge solutions were ready to recognize the virus with some standard and smart electronic devices. Likely, in this paper, a detailed comparative and comprehensive study on circuit architectures of the biomedical devices is presented. Mostly, this study relates the industry standard circuit schemes applicable in non-invasive health monitoring to combat respiratory illnesses. The trending circuit architectural schemes casted-off to tapeout non-invasive health-care devices available in the past literature are meticulously and broadly discussed in this study. Further, the comprehensive comparison of the state of art of the device performance in terms of supply voltage, chip area, sensitivity, dynamic range, etc. is also shown in this paper. The inclusive design processes of the health monitoring devices from Lab to Industry is thoroughly discussed for the readers. The authors think, that this critical review summarising all the trending and most cited health-care devices in a single paper will alternately help the industrialists to adapt and modify the circuit architectures of the health monitoring devices more precisely and straightforwardly. Finally, the demand for health monitoring devices particularly responsible to detect respiratory illnesses, measuring blood pressure and heart-rate is growing widely in the market after the the incident of COVID-19 and other respiratory diseases.

The last two decades have witnessed a dramatic increase in research on low‐dimensional material with exceptional optoelectronic properties. While low‐dimensional materials offer exciting new opportunities for imaging, their integration in practical applications has been slow. In fact, most existing reports are based on single‐pixel devices that cannot rival the quantity and quality of information provided by massively parallelized mega‐pixel imagers based on complementary metal‐oxide semiconductor (CMOS) readout electronics. The first goal of this review is to present new opportunities in producing high‐resolution cameras using these new materials. New photodetection methods and materials in the field are presented, and the challenges involved in their integration on CMOS chips for making high‐resolution cameras are discussed. Practical approaches are then presented to address these challenges and methods to integrate low‐dimensional material on CMOS. It is also shown that such integrations could be used for ultra‐low noise and massively parallel testing of new material and devices. The second goal of this review is to present the colossal untapped potential of low‐dimensional material in enabling the next‐generation of low‐cost and high‐performance cameras. It is proposed that low‐dimensional materials have the natural ability to create excellent bio‐inspired artificial imaging systems with unique features such as in‐pixel computing, multi‐band imaging, and curved retinas.

“…Thus, a display system driven by SWNT TFTs is highly anticipated to contribute to process margins and reliable operation, even under undesirable external illumination, compared with most semiconductors and conventional materials for display backplane TFTs that have considerable photo responses.

Active matrix (AM) quantum‐dot light‐emitting diodes (QLEDs) driven by thin‐film transistors (TFTs) have attracted significant attention for use in next‐generation displays. Several challenges remain for the realisation of AM‐QLEDs, such as device design, fabrication process, and integration between QLEDs and TFTs, depending on their device structures and configurations. Herein, we demonstrate efficient and stable AM‐QLEDs using conventional and inverted structured QLEDs (C‐ and I‐QLEDs, respectively) combined with facile type‐convertible (p‐ and n‐type) single‐walled carbon nanotube (SWNT)‐based TFTs. Based on the four possible configurations of the QLED–TFT subpixel, we compare the performance of the SWNT TFT‐driven QLEDs and the fabrication process to determine the ideal configuration, taking advantage of each structure for AM‐QLEDs. We also optimise the QLEDs and TFTs to maximise the performance of the AM‐QLEDs—the inner shell composition of quantum dots and carrier type of TFTs—resulting in a maximum external quantum efficiency and operational lifetime (at an initial luminance of 100 cd/m2) of 21.2% and 38,100,000 h for the C‐QLED, and 19.1% and 133,100,000 h for the I‐QLED, respectively. Finally, we successfully demonstrate a 5×5 AM‐QLED display array controlled using SWNT TFTs. This study is expected to contribute to the development of advanced AM‐QLED displays.This article is protected by copyright. All rights reserved
