“…To be used as a prosthetic hand, an actuator, battery, and controller should be integrated into the hand, and the fingers should be easily replaceable for repair. Although our research group reported a three-fingered prosthetic hand in 2013 [22], its effectiveness as a prosthetic hand was not sufficiently demonstrated.…”

Forearm amputees can use body-powered hooks and myoelectric hands for their daily activities. The body-powered hooks are suitable for delicate manipulation. However, their appearance is not always preferred by amputees, and a harness to pull a control cable is not easy to wear. Although the myoelectric hands have a natural appearance similar to the human hand and can be intuitively controlled by a myoelectric control system, they are not easy to try out and are heavy. This paper reports on the Finch, a prosthetic arm with three opposing fingers controlled by a muscle bulge. The aim of developing the Finch is to realize a lightweight prosthetic arm that is easy to wear and use. Three opposing fingers are controlled according to the degree of muscle bulge measured with a muscle bulge sensor on the user's forearm caused by muscle contraction. A supporter socket, consisting of a resin socket frame and a fabric supporter, allows easy fitting. A simple design using a linear actuator and 3D-printed parts achieved light weight (330 g) and low cost. Six functional tests and user tests using Southampton Hand Assessment Procedure showed that the Finch had a practical function that could be used in daily activities.

“…In spite of the fast progress in medical science over recent decades, patients of upper limb amputation have only little change in the daily life [1]. In fact, the amputees thought that most of the upper limb prostheses are still as a hook at the end of the arm [2]. According to the statistical study that has been made on 2477 amputees of upper limb mutilation [3], the basic requirement of the typical upper limb prostheses are: (i) enable the users to perform their daily life activities with less visual attention required, (ii) allow the patients to manipulate different sizes of objects as easy as possible, and (iii) design a prosthetic hand which has the highest similarity to the healthy human hand in overall appearance and functionality.…”

Myoelectric prostheses have seen an increased application in clinical practice and research, due to their potential for good functionality and versatility. Yet, myoelectric prostheses still suffer from a lack of intuitive control and haptic feedback, which can frustrate users and lead to abandonment. To address this problem, a prosthetic arm was designed to help the amputees, who unfortunately lost their upper limb. Then, the prosthetic arm was equipped with a hybrid haptic feedback stimulation system to compensate for the missing sensation and enable the amputees to easily perform their normal life activities. The tracking system between the elbow joints of the human and the prosthetic arms was required to accomplish the experimental tests with the able-body subjects. Accordingly, this study is a platform for the main project. The major problem is to synchronize the movements of the prosthetic arm's elbow joint with the human arm's elbow joint within a high response, acceptable accuracy, and low error. Therefore, the PID controller was used to control the tracking system and the flexible bending sensor was attached to the volunteer's elbow joint to record its rotational movements. The results verified the functionality of the proposed tracking system to synchronize the joints movements and enable the prosthetic arm to follow the movements of the volunteer's arm within 0.062 sec. Finally, the effectiveness of the proposed elbow joints tracking system to synchronize the motions of the volunteer and he prosthetic arms was concluded.

“…Many researches in prosthetic hand are aimed to get the prosthesis more lightweight, easy to maintenance, and low cost. Low cost myoelectric prosthetic hands for transradial prosthesis have been studied and developed based on 3D print technology [1][2][3][4]. The prosthetic hands show the promising results in object manipulation task such as grasp and hold an object in different size and shape.…”

This paper presents the development of new type of wearable robot namely Supernumerary Robotic Finger (SRF) as an assistive robot for healthy people or people with hemiparesis or hemiplegia. SRF comprises of two manipulators attached in user's wrist. Three flex sensors are utilized to measure the finger bending of the user's finger. The posture of SRF is driven by modified glove sensor. The kinematics of both robotic thumb (RT) and robotic finger (RF) is studied using D-H parameter method and RoboAnalyzer software in order to understand the kinematic behavior of this robot. Each of RT and RF has three degrees of freedom (DOF). The posture of RT and RF is controlled using bending angles of thumb and finger from the user that are read by flex sensor. Based on the experimental results for people with healthy hand, the proposed SRF can assist object manipulation task in grasping, holding, and manipulating an object by using single hand when normally it only can be done by using two hands. From the experimental results on a person with healthy hand, the proposed of SRF can be employed as an assistive device for people with hemiparesis or hemiplegia. This device will enable people with diminished hand function work more independently.
