Recent developments have led to the creation of wearable technology. Smartwatches, Google Glass and other wearable devices have been designed with a variety of uses, often connecting with users’ smartphones. The next step beyond wearing tech devices might be actually putting them into people’s bodies. And as bizarre as that idea may sound, it’s already a common part of several medical treatments. Since the late 1950s, heart doctors have been implanting electronic devices to regulate their patients’ heartbeats. These devices, called artificial pacemakers, help millions of heart patients around the world.
a variety of：各種各樣的（= all sorts of、all kinds of）
Cochlear implants, electronic devices implanted in the ear, have been helping people with hearing loss improve their perception of sound for decades. Recently, other devices have been developed for people with vision loss. Early this year, doctors at the University of Michigan’s Kellogg Eye Center performed surgeries to implant the first two artificial retinas. The device, called the ArgusⓇⅡ Retinal Prosthesis System, is designed to help patients with certain inherited retinal diseases recover partial vision. The system uses a small amount of electricity to stimulate the patient’s retina, giving them the ability to detect patterns of light.
