Core Viewpoint - A research team from the Shenyang Materials Science National Research Center has developed a biomimetic adjustable sensitivity phototransistor inspired by the human eye's visual adaptation mechanism, providing a new solution for high-sensitivity and noise-resistant detection of low-contrast targets under complex lighting conditions [1][2]. Group 1: Innovation and Design - The new phototransistor's biomimetic design addresses the challenge of detecting low-contrast targets and offers a new direction for the development of intelligent sensing devices [1]. - The core component of the device is a "gate light-sensitive window" made from specially treated molybdenum disulfide, which automatically adjusts its conductivity based on light intensity [2]. Group 2: Functionality and Performance - The device can dynamically adjust its sensitivity, akin to an "intelligent aperture," allowing it to amplify weak light signal changes while suppressing irrelevant background light or noise [2]. - Experimental data indicates that the sensitivity of this biomimetic photodetector exceeds traditional devices by over 1000 times when detecting low-contrast targets, maintaining stable and clear identification of key features even in strong and chaotic lighting conditions [4].
