Flexible Brain-Like Chips Could Finally Make Robots Truly Adaptable
Researchers have created artificial neurons from organic materials that mimic how biological brains sense and respond to the world—potentially replacing rigid silicon-based systems. The breakthrough could enable softer, biocompatible robots and wearables that adapt in real-time, opening new markets in healthcare devices and autonomous systems where current AI hardware falls short.
Originaltitel: Organic electrochemical neurons for neuromorphic perception
<p>Neuromorphic sensing and processing has the potential to be used to create bioelectronic and robotic systems that perceive, respond and adapt to environmental changes accurately and swiftly. However, the reliance on silicon or other inorganic materials as the basis for artificial neurons in neuromorphic sensors restricts the flexibility, biocompatibility and multisensory capabilities of such systems. Here we explore the potential of organic electrochemical neurons based on organic electrochemical transistors for neuromorphic sensing and perception. We examine how neurons and systems based on organic electrochemical transistors can emulate the sensory principles of living organisms and consider the strengths and weaknesses of organic electrochemical neuron technology in mimicking biological principles. We also outline strategies for advancing the technology at the level of materials, devices, circuits and systems. This Perspective explores the potential of organic electrochemical neurons, which are based on organic electrochemical transistors, in the development of adaptable and biointegrable neuromorphic event-based sensing applications.</p>
