Subthreshold conduction

Some devices exploit sub-threshold conduction to process data without fully turning on or off. Even in standard transistors a small amount of current leaks even when they are technically switched off. Some sub-threshold devices have been able to operate with between 1 and 0.1 percent of the power of standard chips. Such lower power operations allow some devices to function with the small amounts of power that can be scavenged without an attached power supply, such as a wearable EKG monitor that can run entirely on body heat. ==See also==
