The smart bracelet (100) has a length direction, and includes: a first pulse detector (12) and a blood flow sensor (11) sequentially arranged along the length direction, wherein, the blood flow sensor (11) is configured for identifying a blood flow direction and sending a blood flow direction signal; the first pulse detector (12) is configured for detecting a pulse signal. The smart bracelet (100) can intelligently detect whether it is worn on a left hand or a right hand and avoid manually input. ## Claims ### Claim 1 A smart bracelet, having a length direction, comprising: a first pulse detector and a blood flow sensor sequentially arranged along the length direction, wherein, the blood flow sensor is configured for identifying a blood flow direction and generating and sending a blood flow direction signal, the blood flow direction is a direction away from the smart bracelet or a direction that flows to the smart bracelet; the first pulse detector is configured for detecting a pulse signal, the smart bracelet further comprises a processor in communicatively connection with the blood flow sensor and the first pulse detector, the processor being configured for receiving the blood flow direction signal sent by the blood flow sensor, and determining whether the smart bracelet is worn on a left hand or a right hand of a human body according to both of the received blood flow direction signal and whether or not the first pulse detector detects a pulse signal. ### Claim 2 (depends on 1) The smart bracelet according to claim 1, wherein, the first pulse detector is configured to have a left-hand overlapping position which overlaps with a left-hand pulse line in a case where the smart bracelet is worn on a left hand of a human body, and have a right-hand overlapping position which overlaps with a right-hand pulse line in a case where the smart bracelet is worn on a right hand of a human body. ### Claim 3 (depends on 1) The smart bracelet according to claim 1, wherein, the first pulse detector is further configured for transmitting information that no pulse signal is detected to the processor in a case where no pulse signal is detected; or, the first pulse detector is further configured for transmitting no information to the processor in a case where no pulse signal is detected. ### Claim 4 (depends on 1) The smart bracelet according to claim 1, further comprising: a second pulse detector, wherein, the first pulse detector, the blood flow sensor, and the second pulse detector are sequentially arranged along the length direction, and the second pulse detector is configured for detecting a pulse signal. ### Claim 5 (depends on 4) The smart bracelet according to claim 4, further comprising: a processor communicatively connected with the blood flow sensor, the first pulse detector, and the second pulse detector, the processor being configured for receiving a blood flow direction signal sent by the blood flow sensor, and determining whether the smart bracelet is worn on a left hand or a right hand of a human body according to the received blood flow direction signal and whether or not the first pulse detector and the second pulse detector detect a pulse signal. ### Claim 6 (depends on 4) The smart bracelet according to claim 4, wherein, the second pulse detector is configured to have a left-hand overlapping position which overlaps with a left-hand pulse line in a case where the smart bracelet is worn on a left hand of a human body, and have a right-hand overlapping position which overlaps with a right-hand pulse line in a case where the smart bracelet is worn on a right hand of a human body. ### Claim 7 (depends on 5) The smart bracelet according to claim 5, wherein, the second pulse detector is further configured for transmitting information that no pulse signal is detected to the processor in a case where no pulse signal is detected; or, the second pulse detector is further configured for transmitting no information to the processor in a case where no pulse signal is detected. ### Claim 8 (depends on 1) The smart bracelet according to claim 1, wherein, the smart bracelet can be spread out as a flat band. ### Claim 9 (depends on 4) The smart bracelet according to claim 4, wherein, the blood flow sensor, the first pulse detector, and the second pulse detector are located on one end of the smart bracelet in the length direction. ### Claim 10 (depends on 1) The smart bracelet according to claim 1, wherein, the blood flow sensor is a Doppler blood flow sensor. ### Claim 11 (depends on 1) The smart bracelet according to claim 1, further comprising: an information transmitter in connection with the processor; the information transmitter is configured for receiving information that the smart bracelet is worn on a left hand or a right hand of a human body which is determined by the processor, and transmitting the information to a terminal. ### Claim 12 (depends on 1) The smart bracelet according to claim 1, further comprising: an information receiver in connection with the processor; the information receiver being configured for receiving information transmitted by the terminal, and transmitting the information to the processor. ### Claim 13 (depends on 1) The smart bracelet according to claim 1, further comprising: a display screen connected with the processor and configured for displaying information determined by the processor; the information at least including an information determined by the processor that the smart bracelet is worn on a left hand or a right hand of a human body. ### Claim 14 (depends on 1) The smart bracelet according to claim 1, wherein, the first pulse detector is configured to have a left-hand overlapping position which overlaps with a left-hand pulse line in a case where the smart bracelet is worn on a left hand of a human body, and have a right-hand overlapping position which overlaps with a right-hand pulse line in a case where the smart bracelet is worn on a right hand of a human body. ### Claim 15 (depends on 1) The smart bracelet according to claim 1, further comprising: a second pulse detector, wherein, the first pulse detector, the blood flow sensor, and the second pulse detector are sequentially arranged along the length direction, and the second pulse detector is configured for detecting a pulse signal. ### Claim 16 (depends on 2) The smart bracelet according to claim 2, further comprising: a second pulse detector, wherein, the first pulse detector, the blood flow sensor, and the second pulse detector are sequentially arranged along the length direction, and the second pulse detector is configured for detecting a pulse signal. ### Claim 17 (depends on 3) The smart bracelet according to claim 3, further comprising: a second pulse detector, wherein, the first pulse detector, the blood flow sensor, and the second pulse detector are sequentially arranged along the length direction, and the second pulse detector is configured for detecting a pulse signal. ### Claim 18 (depends on 5) The smart bracelet according to claim 5, wherein, the second pulse detector is configured to have a left-hand overlapping position which overlaps with a left-hand pulse line in a case where the smart bracelet is worn on a left hand of a human body, and have a right-hand overlapping position which overlaps with a right-hand pulse line in a case where the smart bracelet is worn on a right hand of a human body. ### Claim 19 (depends on 5) The smart bracelet according to claim 5, further comprising: an information transmitter in connection with the processor;
