Title: Innovations in Prosthetics by Tianjian Chen

Introduction

Tianjian Chen is an accomplished inventor based in Pittsburgh, PA (US), known for his significant contributions to the field of prosthetics. With a focus on enhancing the functionality and usability of prosthetic devices, he has been awarded 2 patents for his innovative designs and methodologies.

Latest Patents

Chen's latest patents include groundbreaking inventions aimed at improving amputee gait capacity assessment. The first patent presents two embodiments of a tethered ankle-foot prosthesis. One embodiment features a single toe designed to provide plantarflexion, while the other includes two independently-actuated toes that work together to deliver plantarflexion and inversion-eversion torques. This invention integrates an end-effector worn by the subject with existing off-board motor and control hardware, enabling high bandwidth torque control. The platform is particularly suitable for haptic rendering of virtual devices in human experiments, which may uncover strategies for enhancing balance or facilitate controlled comparisons of conventional prosthesis features. A similar morphology is also effective for autonomous devices.

The second patent focuses on a tethered ankle-foot prosthesis emulator that incorporates two independently-actuated forefoot digits and an independently-actuated heel. This design also aims to provide plantarflexion and inversion-eversion torques. Like the first patent, it includes an end-effector that integrates with off-board motor and control hardware for high bandwidth torque control. This platform is designed for haptic rendering of virtual devices in human experiments, potentially revealing strategies for improving balance and allowing for controlled comparisons of conventional prosthesis features.
