Shaping high-performance wearable robots for human motor and sensory reconstruction and enhancement

Nature Communications, Год журнала: 2024, Номер 15(1)

Опубликована: Фев. 26, 2024

Abstract Most wearable robots such as exoskeletons and prostheses can operate with dexterity, while wearers do not perceive them part of their bodies. In this perspective, we contend that integrating environmental, physiological, physical information through multi-modal fusion, incorporating human-in-the-loop control, utilizing neuromuscular interface, employing flexible electronics, acquiring processing human-robot biomechatronic chips, should all be leveraged towards building the next generation robots. These technologies could improve embodiment With optimizations in mechanical structure clinical training, better facilitate human motor sensory reconstruction enhancement.

Conductive polymers are of great interest in the field neural electrodes because their potential to improve interfacial properties electrodes. In particular, conductive polymer poly (3,4)-ethylenedioxithiophene (PEDOT) has been widely studied for applications.Objective:This review compares methods electrodeposition PEDOT on metal electrodes, and analyses effects deposition morphology electrochemical performance.Approach:Electrochemical performances were analysed against several method choices, including charge density co-ion, correlations explained morphological structural arguments as well characterisation choices.Main results:Coating thickness storage capacity positively correlated with density. We also show that coated electrode impedance at 1 kHz, only consistently reported quantity, is strongly dependent upon radius across a wide range studies, coatings reduces reactance complex impedance, conferring more resistive behaviour (at kHz) dominated by solution resistance geometry. This summarises how co-ion choice affects coating structure shows co-ions notably influence injection limit but have limited impedance. Finally we discuss possible assess robustness comparisons between published results using different characterisation.Significance:This aims serve common basis researchers working showing performance, set standard accurate uniform reporting methods.
