Problems solved by technology
If the instrument used in this kind of biochemical or medical testing is powered by general household electricity or hospital power generation device, it is less likely to cause the instrument to fail to work due to insufficient power.
However, a small biochemical or medical testing instrument may use a battery with a low capacity as its power source. When the battery is low, the small biochemical or medical testing instrument may lose its effectiveness and fail to achieve the detection purpose. Real-time monitoring of the patient's status and delays in emergency response when an accident occurs

Embodiment Construction
[0040] see figure 1 , figure 1 A schematic diagram of a sensing element 1 according to a specific embodiment of the invention is shown. Such as figure 1As shown, the sensing element 1 includes a flow channel 10 , a bubble generator 12 and a sensor 14 . Wherein, the flow channel 10 can accommodate the fluid 100 , and the bubble generator 12 and the sensor 14 are disposed on the inner wall of the flow channel 10 .
[0041] In this specific embodiment, the bubble generator 12 can be coupled to the power supply P to receive power provided by the power supply P to generate at least one bubble 102 . Please note that actually the power supply P can be a built-in power supply of the sensing element 1 or a power supply of another electronic device, depending on the needs of users or designers.
[0042] exist figure 1 Only one air bubble 102 is shown in the figure, but in fact, according to the different types of the air bubble generator 12 , different sizes or different numbers of...

The invention discloses a sensing element, which includes a flow channel, a bubble generator and a sensor. The flow channel includes an inner wall for containing fluid; the bubble generator is arranged on the inner wall and coupled to a power supply, and the bubble generator generates at least one bubble through the power provided by the power supply; the sensor is arranged on the inner wall and used To sense the electrical characteristics around it and generate sensing signals according to the electrical characteristics. When the bubble generated by the bubble generator approaches the sensor and affects the electrical characteristic around the sensor, the sensor adjusts the sensing signal according to the change of the electrical characteristic. The invention also discloses a power sensing device including a sensing element, which can be used to sense the power power of the electronic device.
Description
technical field [0001] The present invention relates to a sensing element and an electrical quantity sensing device using the sensing element, and in particular, the present invention relates to a sensing element affecting electrical characteristics by air bubbles and an electrical quantity sensing device using the sensing element. Background technique [0002] In the microstructure, especially the fluid-filled microchannel used in biochemical detection, the properties of the bubbles inside it are very different from those of the surrounding medium. Therefore, the position of the bubbles and the process of bubble generation can be used for different applications. [0003] For example, US Pat. No. 4,175,289 discloses a data storage device using different positions of magnetic bubbles as read-like 0 / 1 states. In addition, US Pat. No. 6,707,592 and US Pat. No. 7,206,474 respectively disclose a communication device, which uses the difference in refractive index between the bubbl...
