A BPS for spatiotemporal decoding of haptic and pain stimuli in prostheses. (IMAGE)
Caption
(A) Schematic comparison of the BPS architecture and its tactile sensing system with the biological haptic and pain sensory system in human skin. (B) Detailed structure of BPS comprising a piezoelectric-based haptic sensing module for real-time localization and intensity detection, and a piezoresistive-based pain sensing module integrated with electrolyte-gated transistors to achieve pain-related temporal integration and synaptic plasticity. (C) Comparison of the sensory functionality between our BPS and previously reported sensing systems, highlighting the more comprehensive and robust sensory performance of our design. (D) Implementation schematic and feasibility trials showing the BPS integrated into prosthetic limbs, providing accurate quantitative evaluation of haptic sensations and pain stimuli, thus aiding in prosthesis fitting, limb health monitoring, and rehabilitation for individuals with limb amputation.
