The artificial skin incorporates sensors for different sensations like heat, cold, and pressure, similar to human skin. These sensors transmit data as a stream of activity spikes, mirroring the neural activity in the human nervous system. This approach allows the artificial skin to integrate seamlessly with specialized chips designed to run neural networks using spiking signals.
The complexity of the nervous system has long been a source of inspiration for computer scientists. The nervous system tracks sensory information using a noisy stream of activity spikes that may be transmitted to hundreds of additional neurons, where they are integrated with similar spike trains coming from still other neurons. The new artificial skin adopts some of the principles of how signals from our sensory neurons are transmitted and integrated.
While the system incorporates some non-neural features, the primary advantage is its compatibility with existing spiking neural network chips. This compatibility allows for the integration of energy-efficient hardware to run AI-based control software, potentially leading to significant advancements in robotics and artificial intelligence.
The implications of this technology extend beyond robotics. Artificial skin could be used in prosthetics to provide amputees with a sense of touch, or in wearable devices to monitor health and environmental conditions. The development also highlights the potential for creating more human-like robots that can interact with the world in a more natural and intuitive way.
The researchers are now focused on improving the sensitivity and durability of the artificial skin, as well as exploring new applications for the technology. Future developments may include integrating the artificial skin with more advanced AI algorithms to enable robots to learn and adapt to new environments more effectively.
