“…The design of the wireless image sensor node can depend on the specific application. In the case of ensuring energy supply, if the specific application field has higher requirements for data processing capabilities, you can use highperformance processors [13] and other related hardware. For example, SensEye has made some attempts in this regard.…”

Diabetes is a chronic metabolic disease with abnormal blood glucose and lipid metabolism caused by insufficient insulin secretion, which seriously affects human health. For solving the problem of treating diabetes, it is particularly important to observe the research progress of the molecular mechanism of EGCG3 ″ Me in the treatment of diabetes based on visual sensor images. This research has not been verified in practice, but many scientists are already studying it. This article is aimed at studying the molecular mechanism of using EGCG3 ″ Me to treat diabetes based on visual sensor images. This article introduces the concept and application of visual image sensor in detail, using a superpixel segmentation method to realize image observation. The EGCG3 ″ Me was extracted and used in diabetes treatment experiments. The experimental results showed that the blood glucose of the mice in the experimental group had returned to normal 60 minutes after the administration of glucose in the blank control group, and the blood glucose of the mice in the control group had basically returned to normal after 120 minutes. Compared with the model group, the number of acinar paging and the number of cells in the pancreatic islets increased in the mice after EGCG3 ″ Me treatment, indicating that EGCG3 ″ Me has the effect of protecting and repairing pancreatic islet cells.

Digital media art is a new type of art with rich sensory experience. Nowadays, digitization is flooding many areas of life. Under the sprint of a large amount of information, human beings have once again entered the digital age. This article is aimed at studying the fusion of oil painting art and digital media based on visual sensors, analyzing the application of digital imaging art using sensor technology in various fields, especially in the field of oil painting art, and analyzing the effects of digital media with the support of sensor technology. The artistic characteristics and rich forms of presentation are presented, and then, the key points of digital media design are summarized. This paper proposes to bring advanced sensor technology into the field of art for research, turning boring and difficult technical data into an interesting art form, making human-computer interaction more compact and humane, and creating better works of art, so that more and more people and different fields can enjoy the scientific and technological achievements. The sensor is a kind of bionics in modern science, which enables machinery to perceive the human environment like human or animal sensory organs, through the perception and detection of this environmental change, and writing a certain program, the signal data is converted into electricity or signal, and at the same time transmit these signals to receiving organs or devices, such as device sensors that simulate organs. The art of digital photography requires the intervention of sensor technology to make interaction and virtue more complete. The sensor technology also requires the art of digital photography to provide an external display window, which can better serve mankind and create greater social value. The combination of technology and art makes the presentation of art more distinctive. The experimental results of this paper show that the integration of oil painting art and digital media based on visual sensors has made digital media have an impact on more than 58% of oil painting art works and made many oil painting art works show an unprecedented sense of science and technology, which is important for future oil painting art. The development of the company has positive significance.

“…In many studies, the tactile sensor was intentionally added with a compliant layer similar to the skin. Youngwoo Kim et al designed a fluid-type tactile sensor able to measure the size and depth of heterogeneous substances in elastic bodies that consisted of an image sensor, LED lights, and a touch pad filled with translucent water [10]. The University of Genoa in Italy developed a tactile sensor using piezoelectric conductive rubber as a sensitive material, which consists of 8 × 8 arrays of 64 tactile units.…”

“…In 1991, R. S. Fearing et al [ 8 , 9 ] tried to use a stress/strain distribution model of a flexible skin layer in the contact state to inversely solve the surface curvature based on Hertz contact theory. In 2017, Y. Kim et al [ 10 ] used the flexible surface of the sensor to fit the object, and used the Light Emitting Diode (LED) and Complementary Metal Oxide Semiconductor (CMOS) image sensor to reconstruct the surface contour of the sensor to measure the curvature. There are some based on other methods such as the 2016 Ran Xu et al [ 11 ] study using fiber Bragg grating (FBG) sensors to measure the curvature, but was only limited to complete tubular and cylindrical objects.…”

Object curvature plays an important role in grasping and manipulation. To be more exact, local curvature is a more useful information for grasping practically. Vision and touch are the two main methods to extract surface curvature of an object, but vision is often limited since the complete contact area is invisible during manipulation. In this paper, the authors propose an object curvature estimation method based on an artificial neural network algorithm through a lab-developed sparse tactile sensor array. The compliant layer covering on the sensor is indispensable for fitting the curved surface. Three types (plane, convex sphere, and convex cylinder) of sample and each type of sample including 30 different radiuses (1 mm to 30 mm) were used in the experiment. The overall classification accuracy was 93.1%. The average curvature radius estimating error based on an artificial neural network (ANN) algorithm was 1.87 mm. When the radius of curvature was bigger than 5 mm, the average relative error was smaller than 20%. As a comparison, the sensor array density we used in this paper was less than 9/cm2, which was smaller than the density of human SAII receptors, but the discrimination result was close to the SAII receptors. Comparison with the curvature discrimination ability of the human body showed that this method has a promising application prospect.
