a Schematic illustration of the full-duplex fiber-based wearable LiFi system based on a light-emitting-detecting bi-functional perovskite fiber. The transceiver on the left represents the mobile wearable terminal (MWT) based on perovskite bi-functional fibers; another transceiver represents the terminal that MWT interact with, which is consist of a commercial photodiode (PD) and a laser diode (LD) as the receiver (RX) and transmitter (TX), respectively. Two sets of signals are used to testify its capability of simultaneously transmitting and receiving information. Signal 1 (sine wave) is applied on the fiber to transmit data; Signal 2 (square wave) is applied on the LD to the provide the incoming data that the fiber needs to identify. A superimposed signal which contained the information of the above-mentioned two set of signals is acquired by an oscilloscope, which is clearly distinguishable.
