Prosthetic Control and Sensory Feedback for Upper Limb Amputees

Hand amputation could dramatically degrade the life quality of amputees. Many amputees use prostheses to restore part of the hand functions. Myoelectric prosthesis provides the most dexterous control. However, they are facing high rejection rate. One of th ...

PCA and deep learning based myoelectric grasping control of a prosthetic hand

Huaiqi Huang

Background: For the functional control of prosthetic hand, it is insufficient to obtain only the motion pattern information. As far as practicality is concerned, the control of the prosthetic hand force is indispensable. The application value of prosthetic ...

Multi-modal Sensory Feedback System for Upper Limb Amputees

Christian Enz, Claudio Bruschini, Jörn Justiz, Huaiqi Huang, Tao Li

Providing sensory feedback for myoelectric prosthetic users can not only increase the manipulation ability but can also introduce a feeling of embodiment. Previous research has demonstrated the feasibility of providing mechanotactile or vibrotactile feedba ...

A Miniature Multimodal Actuator for Effective Tactile Feedback: Design and Characterization

Huaiqi Huang, Tao Li

We designed a miniature multimodal actuator by combining servomotors and vibrators. The actuator is mainly designed to non-invasively deliver tactile information to human skin by high-frequency vibration and low-frequency pressures simultaneously. By utili ...

EMG Pattern Recognition Using Decomposition Techniques for Constructing Multiclass Classifiers

Christian Enz, Claudio Bruschini, Jörn Justiz, Huaiqi Huang, Tao Li

To improve the dexterity of multi-functional myoelectric prosthetic hand, more accurate hand gesture recognition based on surface electromyographic (sEMG) signal is needed. This paper evaluates two types of time-domain EMG features, one independent feature ...

Experiment and Investigation of Two Types of Vibrotactile Devices

Christian Enz, Jörn Justiz, Huaiqi Huang, Tao Li

Tactile displays have a wide range of applications in assistive technology, prosthetics, and rehabilitation. Vibrotactile stimulation shows potential to be integrated into wearable devices because of its small size, low power consumption, and relative fast ...

Automatic Hand Phantom Map Detection Methods

Christian Enz, Claudio Bruschini, Jörn Justiz, Huaiqi Huang, Tao Li

Many amputees have maps of referred sensation from their missing hand on their residual limb (phantom maps). This skin area can serve as a target for providing amputees with tactile sensory feedback. Providing tactile feedback on the phantom map can improv ...

Data fusion for a hand prosthesis tactile feedback system

Christian Enz, Jörn Justiz, Huaiqi Huang, Ozan Unsal, Tao Li

Current myoelectrically controlled hand prostheses normally lack tactile feedback, thus limiting their functionalities and user acceptance. We propose a non-invasive tactile sensory feedback system, consisting miniaturized sensors, wireless communication m ...
