Title: SENDING/RECEIVING DEVICE, METHOD FOR SENDING/RECEIVING, AND PROGRAM
Abstract:
The present disclosure relates to a sending/receiving device, a method for sending/receiving and a program with which it is possible, in body-area communication, to send and receive in either a two-pole formation or a three-pole formation by switching therebetween in the same circuit configuration. There are provided a first switch for switching connection with a human body-side electrode on and off that is connected to one transmission driver for transmitting a signal by differential output, and a second switch for switching connection with a space-side electrode on and off that is connected to the other transmission driver. In a two-pole formation, the switch having no electrode connected thereto is fixed to off while in use and the switch having an electrode connected thereto is turned on at transmission time and turned off at reception time, and a terminal having no electrode connected thereto among the terminals connected to a receiving unit is grounded to earth. In a three-pole formation, both switches are turned on at transmission time and turned off at reception time. The present disclosure can be applied to a body-area-network device.
