A finger is a limb of the human body and a type of digit, an organ of manipulation and sensation found in the hands of humans and other primates. Normally humans have five digits, the bones of which are termed phalanges, on each hand, although some people have more or fewer than five due to congenital disorders such as polydactyly or oligodactyly, or accidental or medical amputations. The first digit is the thumb, followed by index finger, middle finger, ring finger, and little finger or pinkie. According to different definitions, the thumb can be called a finger, or not.
In medicine, a prosthesis or prosthetic implant is an artificial device that replaces a missing body part, which may be lost through trauma, disease, or a condition present at birth. Prostheses are intended to restore the normal functions of the missing body part. Amputee rehabilitation is primarily coordinated by a physiatrist as part of an inter-disciplinary team consisting of physiatrists, prosthetists, nurses, physical therapists, and occupational therapists. Prostheses can be created by hand or with computer-aided design (CAD), a software interface that helps creators design and analyze the creation with computer-generated 2-D and 3-D graphics as well as analysis and optimization tools.
The upper limbs or upper extremities are the forelimbs of an upright-postured tetrapod vertebrate, extending from the scapulae and clavicles down to and including the digits, including all the musculatures and ligaments involved with the shoulder, elbow, wrist and knuckle joints. In humans, each upper limb is divided into the arm, forearm and hand, and is primarily used for climbing, lifting and manipulating objects.
Electromyography (EMG) is an electrodiagnostic medicine technique for evaluating and recording the electrical activity produced by skeletal muscles. EMG is performed using an instrument called an electromyograph to produce a record called an electromyogram. An electromyograph detects the electric potential generated by muscle cells when these cells are electrically or neurologically activated. The signals can be analyzed to detect medical abnormalities, activation level, or recruitment order, or to analyze the biomechanics of human or animal movement. In Computer Science, EMG is also used as middleware in gesture recognition towards allowing the input of physical action to a computer as a form of human-computer interaction.
Bio robotics is an interdisciplinary science that combines the fields of biomedical engineering, cybernetics, and robotics to develop new technologies that integrate biology with mechanical systems to develop more efficient communication, alter genetic information, and create machines that imitate biological systems.
The MacRobert Award is regarded as the leading prize recognising UK innovation in engineering by corporations. The winning team receives a gold medal and a cash sum of £50,000.
Neuroprosthetics is a discipline related to neuroscience and biomedical engineering concerned with developing neural prostheses. They are sometimes contrasted with a brain–computer interface, which connects the brain to a computer rather than a device meant to replace missing biological functionality.
Biomechatronics is an applied interdisciplinary science that aims to integrate biology and mechatronics. It also encompasses the fields of robotics and neuroscience. Biomechatronic devices encompass a wide range of applications from the development of prosthetic limbs to engineering solutions concerning respiration, vision, and the cardiovascular system.
The Shirley Ryan AbilityLab, formerly the Rehabilitation Institute of Chicago (RIC), is a not-for-profit nationally ranked physical medicine and rehabilitation research hospital based in Chicago, Illinois. Founded in 1954, the AbilityLab is designed for patient care, education, and research in physical medicine and rehabilitation. The AbilityLab specializes in rehabilitation for adults and children with the most severe, complex conditions ranging from traumatic brain and spinal cord injury to stroke, amputation and cancer-related impairment. Affiliated with Northwestern University, the hospital is located on the Northwestern Memorial Hospital campus and partners on research and medical efforts.
Proto 2 is the name of the $55 million initiative of the Defense Advanced Research Projects Agency, or DARPA, to create a thought-controlled prosthetic arm. Its predecessor was called Proto 1 and was capable of reasonably complicated movements like rolling the shoulders, wrists, flexing the fingers. etc.
Targeted reinnervation enables amputees to control motorized prosthetic devices and to regain sensory feedback. The method was developed by Dr. Todd Kuiken at Northwestern University and Rehabilitation Institute of Chicago and Dr. Gregory Dumanian at Northwestern University Division of Plastic Surgery.
A visual prosthesis, often referred to as a bionic eye, is an experimental visual device intended to restore functional vision in those suffering from partial or total blindness. Many devices have been developed, usually modeled on the cochlear implant or bionic ear devices, a type of neural prosthesis in use since the mid-1980s. The idea of using electrical current to provide sight dates back to the 18th century, discussed by Benjamin Franklin, Tiberius Cavallo, and Charles LeRoy.
A hand is a prehensile, multi-fingered appendage located at the end of the forearm or forelimb of primates such as humans, chimpanzees, monkeys, and lemurs. A few other vertebrates such as the koala are often described as having "hands" instead of paws on their front limbs. The raccoon is usually described as having "hands" though opposable thumbs are lacking.
The Queen's Award for Enterprise: Innovation (Technology) (2010) was awarded on 21 April 2010, by Queen Elizabeth II.
BeBionic is a commercial prosthetic hand designed to enable amputees to perform everyday activities, such as eating, drinking, writing, typing, turning a key in a lock and picking up small objects.
David James Gow CBE is the inventor of the i-Limb prosthetic hand. He was made an honorary Doctor of Science in November 2018 by the University of Edinburgh.
The Michelangelo Hand is a fully articulated robotic hand prosthesis developed by the German prosthetics company Ottobock and its American partner Advanced Arm Dynamics. It is the first prosthesis to feature an electronically actuated thumb which mimics natural human hand movements. The Michelangelo Hand can be used for a variety of delicate everyday tasks, was first fitted to an Austrian elective-amputee in July 2010 and has been in use by military and civilian amputees in the United States and United Kingdom since 2011.
Argus retinal prosthesis, also known as a bionic eye, is an electronic retinal implant manufactured by the American company Second Sight Medical Products. It is used as a visual prosthesis to improve the vision of people with severe cases of retinitis pigmentosa. The Argus II version of the system was approved for marketing in the European Union in March 2011, and it received approval in the US in February 2013 under a humanitarian device exemption. The Argus II system costs about US$150,000, excluding the cost of the implantation surgery and training to learn to use the device.
Limbitless Solutions is a 501(c)(3) non-profit organization founded in the United States that uses additive manufacturing to create accessible, yet affordable personalized bionics and prosthetic partial arms for children with limb differences The organization says their bionic arms are manufactured for under $400, 1% of the standard production cost. Headquartered on the University of Central Florida campus in Orlando, Florida, the organization was founded by a team of engineering students, led by CEO and Executive Director Albert Manero.
Samantha Payne is the co-founder of Open Bionics, a bionics company developing affordable prosthetics for children.
