The proposed system incorporates an underactuated, cable-driven mechanism combining rigid and compliant elements to achieve passive adaptability and embodied intelligence, supporting intuitive user interaction. Results indicate that the prosthesis successfully mimics natural finger flexion and adapts effectively to a variety of grasping tasks with minimal effort. This study was conducted in accordance with ethical standards and approved by the Institutional Review Board (IRB), Project No. 670161, titled \u201cBiologically-Inspired Synthetic Finger: Design, Fabrication, and Application.\u201d The findings suggest that the device offers a viable and practical solution for individuals with partial hand loss, particularly in settings where electrically powered systems are unsuitable or inaccessible.<\/jats:p>","DOI":"10.3390\/robotics14080107","type":"journal-article","created":{"date-parts":[[2025,8,1]],"date-time":"2025-08-01T06:37:47Z","timestamp":1754030267000},"page":"107","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Body-Powered Underactuated Prosthetic Finger Driven by MCP Joint Motion"],"prefix":"10.3390","volume":"14","author":[{"given":"Worathris","family":"Chungsangsatiporn","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, Faculty of Engineering, Chulalongkorn University, Bangkok 10330, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0285-2090","authenticated-orcid":false,"given":"Chaiwuth","family":"Sithiwichankit","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Faculty of Engineering, Chulalongkorn University, Bangkok 10330, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0409-3860","authenticated-orcid":false,"given":"Ratchatin","family":"Chancharoen","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Faculty of Engineering, Chulalongkorn University, Bangkok 10330, Thailand"},{"name":"Human-Robot Collaboration and Systems Integration Research Unit, Faculty of Engineering, Chulalongkorn University, Bangkok 10330, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5002-7568","authenticated-orcid":false,"given":"Ronnapee","family":"Chaichaowarat","sequence":"additional","affiliation":[{"name":"International School of Engineering, Faculty of Engineering, Chulalongkorn University, Bangkok 10330, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nopdanai","family":"Ajavakom","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Faculty of Engineering, Chulalongkorn University, Bangkok 10330, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6518-0992","authenticated-orcid":false,"given":"Gridsada","family":"Phanomchoeng","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Faculty of Engineering, Chulalongkorn University, Bangkok 10330, Thailand"},{"name":"Human-Robot Collaboration and Systems Integration Research Unit, Faculty of Engineering, Chulalongkorn University, Bangkok 10330, Thailand"},{"name":"Center of Excellence in Applied Medical Virology, Chulalongkorn University, Bangkok 10330, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,31]]},"reference":[{"key":"ref_1","unstructured":"Owings, M.
