Near field communication (NFC) based multiband high-sensitivity brain wave sensing bluetooth earphone

Abstract

The invention discloses a near field communication (NFC) based multiband high-sensitivity brain wave sensing bluetooth earphone, which is characterized in that an earphone body comprises brain wave sensors, filtering and amplification units, a multichannel selection switch, an analog-to-digital converter and a brain wave acquisition and processing chip which are sequentially connected, the brain wave sensors comprise a brain wave sensor A distributed at a brain frontal region and a brain wave sensor B distributed at a brain occipital region, and each filtering and amplification unit comprises a first amplifier, a wave trap, a low-pas filter, a high-pass filter and a second amplifier, which are sequentially connected, of high-impedance differential input. The earphone body further comprises an NFC module, wherein the NFC module is connected with a bluetooth module through a bluetooth control circuit which is used for controlling the bluetooth module to realize automatic matching and communication, and the NFC module is further connected with a target terminal through an NFC transmitting and receiving antenna. The NFC based multiband high-sensitivity brain wave sensing bluetooth earphone enables users to carry out a matching operation directly through NFC, the target terminal is controlled to carry out corresponding actions through brain waves, and the manipulation is convenient.
