Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.
Fig. 1 shows an impedance measuring apparatus 100 according to an embodiment of the present invention. The following embodiment explains the structure of the impedance measuring apparatus 100.
As shown in fig. 1 and 2, the impedance measuring device 100 includes a device body 110, a first electrode assembly 120, and a second electrode assembly 130. The device body 110 has a first end surface 111 and a second end surface 112 facing away from each other, wherein the first end surface 111 is a surface that is close to the object to be measured in use. The first electrode assembly 120 is disposed on the first end surface 111, and the second electrode assembly 130 is disposed on the second end surface 112. And the area of the first electrode assembly is larger than the area of the second electrode assembly, which is an area for contact with the object to be measured.
The impedance measuring apparatus 100 may be used to perform bio-impedance measurement on a subject to be measured, which may be a human body, and the impedance measuring apparatus 100 may perform body fat measurement on the human body, as one mode. The impedance measuring device 100 may include an impedance measuring circuit provided inside the device body 110 and electrically connected to the first electrode assembly 120 and the second electrode assembly 130, respectively. When bio-impedance measurement is performed on a human body, different parts of the human body are respectively in contact with the first electrode assembly 120 disposed on the first end surface 111 of the device body 110 and the second electrode assembly 130 disposed on the second end surface 112 of the device body 110, and at this time, the human body impedance measurement can be completed through the impedance measurement circuit.
The apparatus body 110 includes a display portion 113 and a mounting portion 114, wherein the mounting portion 114 is disposed around the display portion 113. The first end surface 111 is a surface that is close to the measured object in use, that is, the first end surface 111 is located on a side of the device body 110 away from the display portion 113, the second end surface 112 is located on a side of the device body 110 close to the display portion 113, and in some embodiments, the second end surface 112 is disposed on the mounting portion 114. In the case of performing the bioimpedance measurement, the first end surface 111 is closer to the object to be measured than the second end surface 112, and in the case of performing the bioimpedance measurement, the contact area between the first end surface 111 and the object to be measured is larger than the contact area between the second end surface 112 and the object to be measured. For example, when the impedance measuring apparatus 100 is applied to a wearable device, in a case of not performing a biological impedance measurement, a user may wear the impedance measuring apparatus 100, where the first end surface 111 is a wearing surface that is close to and in contact with the user in a wearing state, and the second end surface 112 is a non-contact surface that is not in contact with the user in the wearing state; in the case of performing the bio-impedance measurement, the user may press the second electrode assembly 130 disposed on the second end surface 112 by a finger, when both the first end surface 111 and the second end surface 112 are in contact with the user, but since the first end surface 111 is in full contact with the user and only the second electrode assembly 130 of the second end surface 111 is in contact with the user, the contact area of the first end surface 111 with the user is larger than the contact area of the second end surface 112 with the measured object.
In this embodiment, since the area of the first electrode assembly 120 is larger than that of the second electrode assembly 130, the first electrode assembly is stably contacted with the measured object when the bio-impedance measurement is performed, so that the first electrode assembly 120 on the first end surface 111 of the device body 110 is ensured to be in a larger contact area with the measured object, and since the contact area of the electrode assembly with the measured object is negatively correlated with the contact impedance, the contact impedance between the first electrode assembly 120 and the measured object is lower, thereby ensuring the accuracy of the measurement result.
In some embodiments, the area of the first electrode assembly 120 is at least twice the area of the second electrode assembly 130. Therefore, the first electrode assembly can be ensured to have good contact effect with the measured object when the biological impedance measurement is carried out.

The third electrode 131 and the fourth electrode 132 are spaced apart from each other by a second predetermined distance. The third electrode 131 and the fourth electrode 132 are a pair of excitation electrodes and measurement electrodes. When the third electrode 131 is an excitation electrode, the fourth electrode 132 is a measurement electrode; when the third electrode 131 is a measurement electrode, the fourth electrode 132 is an excitation electrode. In some embodiments, the third electrode 131 and the fourth electrode 132 are disposed on the mounting portion 114 and are oppositely disposed on two sides of the display portion 113, so that a user can conveniently touch the third electrode 131 and the fourth electrode 132.
The area of the first electrode assembly 120 includes a first area of the first electrode 121 and a second area of the second electrode 122. In some embodiments, the first area of the first electrode 121 is the same as the second area of the second electrode 122. In a specific embodiment, the first area of the first electrode 121 and the second area of the second electrode 122 may be 80 to 120 square millimeters. For example, when the area of the first electrode assembly 120 is 100 square millimeters, the first area of the first electrode 121 and the second area of the second electrode 122 are 50 square millimeters. In some other embodiments, the first area of the first electrode 121 and the second area of the second electrode 122 may not be the same. The area of the second electrode assembly 130 includes a third area of the third electrode 131 and a fourth area of the fourth electrode 21. In some embodiments, the third area of the third electrode 131 is the same as the fourth area of the fourth electrode 132. For example, when the area of the second electrode assembly 130 is 60 square millimeters, the corresponding third area of the third electrode 131 and the fourth area of the fourth electrode 132 are 30 square millimeters.
In some embodiments, the first electrode 121 and the third electrode 131 can be the same electrode, e.g., both the first electrode 121 and the third electrode 131 are measurement electrodes, or both the first electrode 121 and the third electrode 131 are excitation electrodes. The first area of the first electrode 121 is greater than the third area of the third electrode 131. The second electrode 122 and the fourth electrode 132 may likewise be the same electrode, for example, the second electrode 122 and the fourth electrode 132 are both measurement electrodes, or the second electrode 122 and the fourth electrode 132 are both excitation electrodes.
