A muscle-signal “smart hand” returns daily tasks to Wang Bing

AI system

System: 'Smart hand' (智能手) muscle-signal prosthetic hand from the institute's exoskeleton robot project
Model: Not assessed
Release: Not assessed
Application developer: Chongqing Bio-Intelligent Manufacturing Research Institute (重庆生物智能制造研究院), Liangjiang New Area
Role: Not assessed
Configuration: Not assessed
Inputs and outputs: Not assessed
Autonomy: Not assessed
Workflow: Electrical signals detectable at suitable muscle sites on the residual forearms. An algorithmic scheme that identifies those signals and maps them to hand and wrist movements. Institute researchers fitting and tuning the device for one user, with district fiscal grants converted to equity.
Human oversight: Not assessed
Relation to AI: The only description of the technology is institute director Xie Haiqiong's, as quoted by Guangming Daily. It is a scheme that detects and identifies electrical signals at suitable muscle sites and processes them by algorithmic analysis. That lets the user control the hand by intention. No source names a machine-learning method, model, training procedure or accuracy figure. The Monitor's “AI-driven” label rests on that description. The functional gains are Wang Bing's own account in a newspaper feature about the district's commercialization policy. No clinician or independent evaluation is cited.

Benefit: Guangming Daily (13 August 2024): Wang Bing, who lost both hands, uses the institute's algorithm-decoded “smart hand” to eat with a spoon, drink, shake hands, rotate his wrist and write his name.

Assessed benefits: People.
Depth: People: 3.
Reasons: People: Per Guangming Daily, Wang Bing, who lost both hands, says he eats with a spoon, drinks from a cup, shakes hands and rotates his wrist. He writes his name and manages daily life alone with the device. A capability restored, reported in his words without clinical assessment.

Field: Healthcare / prosthetics and rehabilitation. Upper-limb prosthetics.
Purpose: Built to let a person with amputated hands control a prosthetic hand through muscle signals. The daily-task function Wang Bing describes is that purpose. The feature frames the project as an example of the district's policy for commercializing research.
