摘 要:The sense of touch is critical to dexterous use of the hands and thus an essential component of efforts to restore hand function after amputation or *** systems have addressed this goal with wearable tactile ***,such wearable sensors are suboptimal for neuroprosthetic systems designed to reanimate a patient’s own paralyzed ***,we developed an implantable tactile sensing system intended for subdermal *** system is composed of a microfabricated capacitive pressure sensor,a custom integrated circuit supporting wireless powering and data transmission,and a laser-fused hermetic silica *** miniature device was validated through simulations,benchtop assessment,and testing in a primate *** sensor implanted in the fingertip accurately measured applied skin forces with a resolution of 4.3 *** output from this novel sensor could be encoded in the brain with microstimulation to provide tactile *** broadly,the materials,system design,and fabrication approach establish new foundational capabilities for various applications of implantable sensing systems.
