TL;DR: By stimulating the median and ulnar nerve fascicles using transversal multichannel intrafascicular electrodes, according to the information provided by the artificial sensors from a hand prosthesis, physiologically appropriate sensory information can be provided to an amputee during the real-time decoding of different grasping tasks to control a dexterous hand prosthetic.

TL;DR: It is shown that texture discrimination can be artificially provided in human subjects by implementing a neuromorphic real-time mechano-neuro-transduction (MNT) process, which emulates to some extent the firing dynamics of SA1 cutaneous afferents.

TL;DR: This work compared the naturalness and efficacy of different encoding strategies to deliver neural stimulation to trans-radial amputees implanted with intraneural electrodes and found that hybrid strategies are able to provide highly sensitive and natural percepts and should be preferred.

TL;DR: This study shows that sensory substitution based on intraneural stimulation can deliver position feedback in real time and in conjunction with somatotopic tactile feedback, and paves a way to more sophisticated bidirectional bionic limbs conveying richer, multimodal sensations.

TL;DR: This study developed a leg neuroprosthesis, which provided real-time tactile and emulated proprioceptive feedback to three transfemoral amputees through nerve stimulation, and demonstrated that induced sensory feedback can be integrated at supraspinal levels to restore functional abilities of the missing leg.
