Wherein, when the first power generation layer 122 in the triboelectric sensor 120 does not form a friction interface with the human skin, one end between the two friction interfaces of the triboelectric sensor 120 can further be provided with a support block 170 to form a cantilever beam friction electric sensor. Specifically, as shown in FIG. 8 and FIG. 9 , the cantilever beam type triboelectric sensor has a first end and a second end, and the support block 170 is arranged at the first end of the triboelectric sensor 120 . Wherein, the above-mentioned first end and the second end are specifically the two ends of the cross-section of the triboelectric sensor 120, and the two are substantially opposite. In specific implementation, the above-mentioned first end can also be regarded as the second end, and the second end It can also be seen as the first end. Wherein, FIG. 8 and FIG. 9 show a structural diagram of a cantilever beam type triboelectric sensor formed by setting a support block 170 on the triboelectric sensor in which the polymer and the electrode layer are rubbed.

In specific implementation, the embedded depth of the cantilever beam triboelectric sensor is less than or equal to the thickness of the cantilever beam triboelectric sensor, so that the free end of the cantilever beam triboelectric sensor can accept external force and contact another friction interface under the action of external force Generates induced charges and outputs electrical signals through wires. Other arrangements of the cantilever beam triboelectric sensor on the glasses body 110 are similar to the arrangement of the triboelectric sensor 120 on the glasses body 110 without cantilever beam friction between the polymer and the electrode layer, and will not be repeated here.

The relevant description of the arrangement of the triboelectric sensor for electrode layer friction on the glasses body will not be repeated here.

The following describes how the above-mentioned triboelectric sensor 120 that does not form a friction interface with human skin is arranged on the glasses body: wherein, the triboelectric sensor 120 can be embedded in the contactable part of the glasses body 110 and human skin. In a specific implementation, the embedding depth of the above-mentioned various types of sensors is in the range of 200-3000 microns. Wherein, FIG. 6 shows a schematic diagram of an embedded structure of a triboelectric sensor 120 on the glasses body. As shown in FIG. 6 , the embedding depth of the triboelectric sensor 120 is equal to the thickness of the triboelectric sensor, so that the outer surface of the triboelectric layer 123 and the outer surface of the eyeglass body are in the same plane.

Further, when the triboelectric sensor is a sensor type that does not form a friction layer with the human skin, an encapsulation layer 150 may be further provided on the outer surface of the side close to the human skin to protect the internal structure of the triboelectric sensor and prevent the triboelectric The internal structure of the sensor is affected by factors such as external moisture, which reduces the accuracy of the generator sensor. In addition, optionally, the encapsulation layer 150 can be wrapped on the outer surface of the triboelectric sensor, or arranged on the outermost surface of the accessible part, so as to also protect the internal structure of the triboelectric sensor and prevent the internal structure of the triboelectric sensor from being damaged by the outside. Moisture and other factors lead to the reduction of the accuracy of the triboelectric sensor. Wherein, the material of the above-mentioned encapsulation layer 150 is a flexible material, preferably a PDMS film, and its outer surface can also be polished to form a micro-nano structure, which can improve the friction effect while ensuring the lightness of the glasses body.

Further, the way of setting the packaging layer for the piezoelectric sensor or the triboelectric and piezoelectric hybrid sensor is similar to the way of setting the packaging layer for the triboelectric sensor, which will not be repeated here.

Further, taking FIG. 6 and FIG. 7 as an example, when the triboelectric sensor 120 is provided with an encapsulation layer, the second electrode layer 123 or the second power generation layer and the second electrode layer 123 can be provided on the encapsulation layer, so that the second A gap is formed between the power generation layer and the first power generation layer or between the second electrode layer and the first power generation layer. This arrangement is more conducive to the contact separation of the friction interface and makes the electrical signal output by the sensor stronger.

In addition, in order to increase the sensitivity of the triboelectric sensor, an elastic element 160 can also be provided between the glasses body 110 and the first electrode layer 121 , and the elastic element 160 is embedded in the glasses body. As shown in Figure 7. Wherein, the number of the above-mentioned elastic elements 160 is preferably multiple, and they are preferably arranged symmetrically between the glasses body and the first electrode layer 121 . The elastic element 160 can effectively increase the contact separation speed between the friction interfaces of the sensors, thereby effectively increasing the sensitivity of the triboelectric sensor and further improving the accuracy of the sensor output sensing signal.

Further, the manner of arranging the elastic element in the piezoelectric sensor or the triboelectric and piezoelectric hybrid sensor is similar to the arranging elastic element in the triboelectric sensor, which will not be repeated here.

Since the above sensor has the characteristics of simple structure, light weight and small size, by setting the sensor on the glasses body, it can not only generate corresponding sensing signals according to the preset actions of the human body, so as to obtain the information of human body actions, but also make the smart glasses The glasses maintain a small volume and quality, simplify the structure of smart glasses, and make them more portable and beautiful. After the triboelectric sensor 120 generates the sensing signal, it outputs the sensing signal to the signal processing module through the connected wire.

The signal processing module is embedded in the glasses body and is electrically connected to the sensor for collecting and processing the sensing signals output by the sensors, and controlling the smart glasses to perform corresponding intelligent operations according to the processing results. The signal processing module can be embedded in the spectacle frame or temple of the spectacle body 110, and is electrically connected to the sensor through a wire, so as to receive the sensing signal output by the sensor through the wire. In specific implementation, when setting the above-mentioned wires, the above-mentioned wires can be arranged along the inside of the frame, so that not only can the smart glasses look light and beautiful in appearance, but also can effectively protect the wires and prevent the wires from being used. During the process, wear and other conditions occur due to friction with the outside world, which affects the sensitivity and accuracy of sensor signal transmission.

Wherein, the signal processing module is used to receive and process the sensing signal output by the sensor, and control the smart glasses to perform corresponding smart operations according to the processing result.

Specifically, in order to ensure the accuracy of smart glasses control, when the signal processing module processes at least one sensing signal, the specific process may be: judge the received sensing signal output by each sensor in the at least one sensor Whether the peak value is greater than or equal to a preset threshold (the preset threshold can be a voltage threshold, etc.), if so, it means that the intensity of the sensing signal is sufficient, and then the smart glasses are controlled to perform corresponding operations. If not, it means that the sensing signal strength is too weak, and no corresponding operation is performed on the smart glasses. Wherein, the size of the above-mentioned preset threshold can be set by those skilled in the art according to the actual situation, which is not limited by the stinger in the present invention. The validity of the sensing signal can be judged through the above method, so as to ensure the accuracy of the corresponding operation performed by the smart glasses.

For example, set the peak voltage threshold as V ₀ , and the peak voltage of the received sensing signal is V _X . When V _X >V ₀ , it is determined that the output sensing signal is valid; when V _X <V ₀ , it is determined that the output Sensing signal is invalid. Among them, since the voltage peak threshold is affected by the structural characteristics of the glasses body itself and the sensor itself, in specific implementation, different voltage peak thresholds are set correspondingly for different types of smart glasses products designed, so that the The processing result of the sensing signal is more accurate. That is to say, in specific implementation, the size of the voltage peak threshold is set according to the structural features such as the size, shape and type of the glasses body, and in combination with the structural features such as the size and type of the sensor arranged on the glasses body. Personnel do not limit the specific value of the voltage peak threshold.

Wherein, when determining the signal type output by the sensor, the signal processing module respectively detects the number of times that the peak value of the sensing signal of each sensor within the preset time interval is greater than or equal to the preset threshold, and if the number of times is the same as the preset number of times, then Control smart glasses to perform corresponding operations. Wherein, when counting the number of preset thresholds, it can be realized by setting a counter in the sensor. The foregoing preset time interval and preset threshold can be set by those skilled in the art according to actual conditions, which are not limited in the present invention. In a specific implementation, the above detection process is suitable for detecting human eye blinking. For example, if the preset time interval is T, if the left eye of the human eye is set to blink twice, the camera operation will be performed. When the left eye of the human eye blinks once, the signal processing module will detect that the peak value of the sensing signal output by the sensor is greater than the preset threshold , then count once at this time, when it is detected that the peak value of the sensing signal output by the sensor again within the T time is greater than the preset threshold, then count again on the basis of the above count at this time, and the count at this time is 2 times, then the central The control module controls the smart glasses to perform a corresponding photographing operation.

When the number of sensors is at least two, and at least two sensors are arranged symmetrically on the glasses body, the signal processing module is further used to: determine whether the peak value of the sensing signal of at least one sensor on the left and right sides of the glasses body 110 is greater than Or equal to the preset threshold, that is to judge whether the left and right eyes of the user perform preset actions at the same time, for example, the user performs the action of blinking the left and right eyes, and at this time, the symmetrically arranged sensors should output sensing signals at the same time. If the determination result is yes, the smart glasses are controlled to perform corresponding operations according to the generation order of the sensing signals of the sensors on the left and right sides. In a specific implementation, a corresponding controller may be provided in the signal processing module for judging the generation sequence of the received sensing signals. Wherein, the specific implementation manner of the controller judging the generation sequence of the sensing signals can be set by those skilled in the art according to the actual situation, which is not limited in the present invention.

When there are at least two sensors, which can be symmetrically or asymmetrically arranged on the glasses body, the signal processing module is further used to: determine whether the peak values of the sensing signals of at least two sensors are greater than or equal to a preset threshold. If it is judged that the user's teeth are engaged to perform a preset action, at least two sensors should simultaneously output sensing signals. If the judgment result is yes, the smart glasses are controlled to perform corresponding operations according to the electrical signals simultaneously output from at least two sensors.

Optionally, it is also possible to process the sensing signal by judging whether the receiving time interval between two adjacent sensing signals is greater than a preset time interval threshold, and if the judgment result is yes, then judging that the sensing signal is valid And input the corresponding processing signal; if the judgment result is no, it is judged that the sensing signal is invalid, and the sensing signal is not processed. For example, set the time interval threshold as T ₀ , and the time interval of the received sensing signal as T _X , when T _X > T ₀ , it is determined that the output sensing signal is valid; when T _X < V ₀ , it is determined that the output The sensing signal is invalid.

Here, it should be noted that the above voltage peak threshold and time interval threshold can be set by those skilled in the art according to actual conditions, which is not limited in the present invention.
