A collaborative research effort between Singapore and China has resulted in a groundbreaking development: an artificial retina device capable of perceiving and encoding mid-infrared radiation. Inspired by the intricate structure of the human retina, this innovation has enormous potential for various applications, including medical diagnosis, autonomous driving and advanced night vision systems.
The artificial retina is constructed as a compact two-dimensional (2D) heterostructure composed of boron arsenide (b-AsP) and molybdenum diselenide (MoTe2). The b-AsP layer functions as an absorber, selectively capturing mid-infrared radiation, while the MoTe2 layer generates the corresponding electrical signals. These electrical signals are then effectively encoded into a series of spikes, facilitating subsequent decoding by a neural network to form a coherent image.
Compared to conventional mid-infrared sensors, the artificial retina offers several advantages. In particular, its compact size and higher efficiency make it an ideal solution for applications with strict space and power limitations. Additionally, its ability to detect objects beyond the range of human perception makes it invaluable in a multitude of scenarios. In addition, the device shows adaptability to fluctuations in light intensity, an indispensable attribute for applications such as autonomous driving.
The successful development of the artificial retina represents an important advance in imaging technologies. Its potential to revolutionize various industries, including medical diagnostics, security and manufacturing, is truly remarkable.
Artificial retina: applications
- Medical diagnosis: By detecting mid-infrared radiation, the artificial retina can help identify diseases that emit such radiation, such as cancer and heart disease.
- Autonomous driving: Enhanced artificial retinal perception enables autonomous vehicles to detect pedestrians, cyclists, and other objects that elude human vision, significantly improving safety.
- Advanced Night Vision: The capabilities of the artificial retina offer the potential for night vision devices that surpass current models in both efficiency and effectiveness.
- Military Defense: The ability of the artificial retina to detect and track targets that emit radiation in the mid-infrared, such as missiles and drones, has important implications for military defense applications.
Although still in the nascent stages of development, the artificial retina holds immense potential to reshape a wide range of industries. Future research and development efforts will undoubtedly transform this device into an essential tool for numerous applications.
The artificial retina is a promising new technology with the potential to significantly improve the lives of millions of people. Through continued research and development, this device can evolve into an invaluable tool in a wide range of applications. Its potential impact spans multiple industries, including medical diagnostics, security, and manufacturing.
