Intrabody Signaling

What Does Intrabody Signaling Mean?

Intrabody signaling uses the human body to transmit low-powered, electrical frequency signals, allowing a person to interact and exchange data with nearby objects. This technology is used to interface between wearable computers and devices, but it is still a prototype. As of 2011, there are no prominent commercial products based on intrabody signaling.


Intrabody signaling is also known as intrabody communication.

Techopedia Explains Intrabody Signaling

The low power used in intrabody signaling ensures that the signals are not felt by and do not propagate to the devices being used by the person.

The communication medium of human touch between devices has the potential for a wide variety of innovative applications. One such example is the Touch and Play Protocol, where the user’s required operation context is provided by touch. This might involve a digital camera user who taps a printer to initiate a printout of camera images via a wireless channel or human transmission. Another implementation example is user interaction with wearable computers via a mouse and keyboard, where intrabody signaling is the interface medium.

Continued safety testing of the effects of low-voltage signal transmission on humans must be analyzed before implementations are established and become available.

Intrabody signaling has many advantages over RF-bands, ISM bands, infrared or conductive fabric:

  • It is touch-sensitive
  • It is less constrained
  • It does not have interception difficulties
  • It can operate on low power
  • It consumer less of a transmission channel
