Using mid-field wireless powering, investigators can transfer power from outside the body to electronics in the gastrointestinal tract. Imagers, gastric pacemakers and other diagnostic and therapeutic tools could someday transform the way diseases of the gastrointestinal tract are measured and treated. But in order for these electronic devices to work, they need a power source. Traditional power sources, eg. batteries, can be incompatible with the mucosal lining and have a limited lifespan within the body. A more promising possibility is to power electronic devices from outside the body...
