Phenotypic variation and thermoregulation of the human hand
The hand has the highest surface area-to-volume ratio of any body part. This property offers the potential for the hand to serve an important function in thermoregulation through radiative heat loss. Theoretically, the capacity for heat loss may be influenced by hand and digit proportions, but the …

Prediction of Human Hand Motions based on Surface Electromyography
Tracking human hand motions has raised more attention due to the recent advancements of virtual reality (Rheingold, 1991) and prosthesis control (Antfolk et al., 2010). Surface electromyography (sEMG) has been the predominant method for sensing electrical activity in biomechanical studies, and has …

A study of vibration response characteristics of the human hand-arm system
… to vibration transmitted to the operators of hand-held power tools has been related to symptoms of vibration white finger (VWF) disease, also known as "Raynaud's Phenomenon of Occupational Origin". Many subjective and objective epidemiological, and clinical studies have established the …

From Rest to Action: Functional Connectivity Architecture of the Human Hand Motor Network
Skillful hand motor control relies on complex interactions within a distributed brain network. Over the past two decades, neuroimaging (fMRI) and neurostimulation (TMS) techniques have greatly advanced our understanding of the functional contributions of individual regions. Yet, a central open …

Cost-Effective Prosthetic Hand Controlled by EMG
<p>A cost-effective five-finger prosthetic hand is designed from aluminum, modeled and controlled using surface Electromyography (EMG) signals, which are obtained from the human body. Force sensors are used to control required forces needed to grasp and pick objects. A prototype hand is developed …

Design of a humanoid hand using segmented shape memory alloy actuators
… field of robotics has yet to produce a robotic hand with the same dexterity as the human hand. There has yet to even be a functioning robotic hand of the same size and weight as the human hand. These deficiencies can be attributed to the size, weight and complexity of the actuators used in these …

An intelligent prosthetic hand using hybrid actuation and myoelectric control
… and development of an intelligent prosthetic hand based on hybrid DC and Shape Memory Alloy (SMA) actuation and controlled by only two myoelectric sensors. A prosthesis as a tool makes no pretence of trying to replace the lost limb physiologically but it works as an aid to help provide some of …
