科学家用导电塑料制成人造神经元，可表现多达17种关键特性

Core Insights - A team from Linköping University in Sweden has developed artificial neurons made from conductive plastics that can simulate advanced functions of biological neurons, exhibiting up to 17 key characteristics [1][2] - This breakthrough in artificial neurons opens up vast prospects for next-generation implantable sensors, medical devices, and advanced robotics [1] Group 1: Technological Advancements - The research demonstrates that organic electronics are not merely flexible alternatives to silicon-based electronics but have the potential to achieve new forms of neuromorphic computing, effectively connecting biology and electronics [2] - The team has simplified the basic structure of artificial neurons, previously achieving 15 out of 22 key characteristics of biological neurons, but the earlier design relied on multiple components, limiting practical applications [2] Group 2: Functional Capabilities - The newly developed artificial neurons can perform a function called "anti-coincidence detection," activating only when one input signal is present while another is absent, a mechanism widely found in the human nervous system [1] - This capability enables the integration of more sensitive and intelligent tactile feedback in prosthetics or robotics in the future [1] Group 3: Biological Compatibility - The new artificial neurons are not only more powerful but also comparable in size to real human nerve cells, demonstrating high biocompatibility and integration potential [2] - This development represents one of the simplest and most biologically relevant artificial neurons reported to date, paving the way for direct integration into living tissues or soft robotic systems [2]
