Detailed Description
Referring to fig. 1, a usage status of the pulse-taking finger-force sensing device 100 according to an embodiment of the present disclosure is schematically illustrated, and the pulse-taking finger-force sensing device 100 is used for sensing a pressing force of a pulse-taking person to a pulse-taking person.
Referring to fig. 1 and fig. 2 together, fig. 2 is a circuit schematic diagram of a pulse-taking finger force sensing device 100 according to an embodiment of the present disclosure. The pulse-taking finger force sensing device 100 includes at least one thin film piezoresistive detector 110, a resistance detection circuit 120 and a processor 130. Here, the number of the thin film piezoresistive detectors 110 is three, and they are respectively configured to be placed on three positions of the cun, guan, and chi on the wrist of the subject. In some embodiments, the number of thin film piezoresistive detectors 110 may be reduced by placing the thin film piezoresistive detectors 110 only at the locations where measurements are desired. The thin film piezoresistive detector 110 changes its resistance value according to its stress.
The resistance detection circuit 120 is electrically connected to the thin film piezoresistive detector 110, and generates a resistance detection signal according to the resistance of the thin film piezoresistive detector 110. The processor 130 is electrically connected to the thin film piezoresistive detector 110 to receive the resistance detection signal. The pressing force of the doctor on cun, guan and chi parts can be returned by the resistance detection signal.
Here, the resistance detection circuit 120 includes at least one voltage divider circuit 140. Each voltage divider circuit 140 includes a first resistor 141 and a second resistor 142 connected in series, wherein the second resistor 142 is the equivalent resistor of the thin film piezoresistive detector 110. Here, the resistance detection signal is a voltage signal, i.e., a voltage value of a node between the first resistor 141 and the second resistor 142. The voltage value reflects the resistance of the second resistor 142, and the pressing force can be derived accordingly.
In some embodiments, the resistance detection circuit 120 can detect the current value passing through the first resistor 141 and the second resistor 142. The current value reflects the change of the resistance value of the second resistor 142, so as to deduce the pressing force.
As shown in fig. 2, the pulse-taking finger force sensing device 100 further includes a storage medium 150 electrically connected to the processor 130 for storing the history of the resistance detection signal as a record. The storage medium 150 may be a non-transitory storage medium such as a memory card, a flash memory, etc. The pulse-taking finger force sensing device 100 further comprises an output interface 160 electrically connected to the processor 130 for outputting the record. The output interface 160 can be a communication interface such as UART, I2C, SPI, USB, etc. for an electronic device to connect. The electronic device may be, for example, a mobile phone, a computer, etc. The electronic device can convert the resistance change in the record into a change in force.
In summary, the pulse-taking finger force sensing device 100 of the present embodiment can measure the force application state of the user during pulse taking, and can provide objective measurement basis.
