In an electrochemical sensor, the potential difference applied to electrochemical batteries is increased at a certain ratio to reduce the transient current.

The invention discloses a Braille convex-concave point control structure, comprising a character post rod, a rod projection, an active board and a control device thereof, and a character post rod motion control device. The rod projection is connected at the lower end of the character post rod which moves up and down through the driving of the character post rod motion control device and the rod projection; the active board is perpendicular to the character post rod, the bottom layer of the active board is provided with a groove; the active board is controlled to translate, and the rod projection enters the groove to drive the character post rod to move up and down. The invention also discloses a progressive full-page driving Braille display, comprising a plurality of square modules each of which is composed of 6 Braille convex-concave point control structures, wherein the structure is arranged in a mode of 3 rows * 2 columns mode; the active boards of the Braille convex-concave point control structures of the square modules in the same line are connected to form an active lath moving together, a waist hole corresponding to the character post rod is arranged on the active lath; in the square modules in the same column, the electromagnetic assemblies of a first Braille convex-concave point control structure, a second Braille convex-concave point control structure and a third Braille convex-concave point control structure in the same column of the square modules are respectively connected to a first driving wire, a second driving wire and a third driving wire which are identical.

The embodiment of the present invention provides a multi-channel switching circuit and switching method, including: a multiplexing switch matrix, the control terminal of the multiplexing switch matrix is ​​connected to a controller; the multiplexing switch matrix includes a plurality of multiplexing Using a switch, each output channel of each multiplexing switch is respectively connected to a sensor circuit; the common end of each multiplexing switch is respectively connected to the first input end of the signal detection circuit; the output end of the signal detection circuit is connected to the control device, the second input end of the signal detection circuit is connected to the output end of the digital-to-analog converter DAC; the input end of the digital-to-analog converter DAC is connected to the controller; the controller is used to control the digital-to-analog conversion when the multiplexing switch switches the output channel The DAC adjusts the bias voltage applied to the input channel of the multiplexing switch according to a preset gradient function. According to the switching circuit of the embodiment of the present invention, the instantaneous current and voltage generated during channel switching can be reduced, thereby reducing the influence on adjacent channels.
