Description: A bionic arm is an artificial limb designed to enhance or replace the function of a human arm. These advanced devices combine robotic technology with biomedical principles to provide users with greater functionality and mobility. Bionic arms can be controlled through electrical signals generated by the user’s muscles, allowing for more natural and precise movement. Additionally, some models are equipped with sensors that provide tactile feedback, enabling users to feel the pressure and texture of the objects they hold. The relevance of bionic arms lies in their ability to improve the quality of life for individuals with amputations or disabilities, giving them the opportunity to perform everyday tasks with greater ease and autonomy. These devices not only represent an advancement in engineering and robotics but also symbolize a step towards the integration of technology into the human body, opening new possibilities in the fields of medicine and rehabilitation.
History: The development of bionic arms began in the 20th century, with the first prototypes of mechanical prosthetics emerging after the world wars. However, true advancement occurred in the 1980s with the introduction of microprocessor-controlled prosthetics. In 1998, Johns Hopkins University presented a bionic arm that could be controlled by neural signals. Since then, technology has rapidly evolved, incorporating lighter and stronger materials, as well as more sophisticated control systems that allow for more natural movement.
Uses: Bionic arms are primarily used in the rehabilitation of individuals who have suffered amputations or have disabilities in their upper limbs. These devices enable users to perform daily activities such as eating, writing, and manipulating objects. Additionally, applications are being explored in various fields, including military and assistive robotics, where they can help individuals with reduced mobility.
Examples: A notable example is the ‘Luke’ bionic arm, developed by the prosthetic technology company Össur, which allows users to control the movement of the hand and fingers through muscle signals. Another case is the ‘DEKA Arm’, designed to offer a wide range of movements and has been used in clinical trials with positive results in improving the quality of life for users.
