Embedded devices, particularly digital ones specially designed to assist individuals with disabilities, are often seen as the next step in that particular field of technology. Such embedded devices generally have several advantages over the previous wave of embedded devices that have monitoring functions, control capabilities, and the ability to access and use communication protocols like the internet. The modern embedded applications devices do not stop monitoring, tracking, and relaying information; they almost always directly assist the user, such as a prosthetic limb or a personal transport assistance vehicle.
Embedded medical and biological application refers to using technology and computers for observing certain events or generating a response when certain events occur. Embedded points to the fact that such devices are either small or very passive or both, such that the subjects of the observations are not continuously aware of it.
