    Abstract: The present disclosure relates to a battery, including a first electrode layer, a second electrode layer, and an electrolyte disposed between the first and second electrode layers. The first electrode layer at least comprises a first electrode and a second electrode, which are spaced apart from each other. An electrolyte is disposed between the first electrode and the second electrode. A polarity of the first electrode is opposite of a polarity of the second electrode. The second electrode layer includes a third electrode disposed on an end opposite to the first electrode and a fourth electrode disposed on an end opposite to the second electrode. An electrolyte is disposed between the third electrode and the fourth electrode. A polarity of the third electrode is the same as that of the second electrode, and a polarity of the fourth electrode is the same as that of the first electrode.

    Abstract: A data caching circuit includes a ring signal counter, a switch, and a first latch. An output terminal of the ring signal counter is connected to a control terminal of the switch. An output terminal of the switch is connected to a control terminal of the first latch. The ring signal counter is configured to input a data transmission starting signal and a clock signal to generate and output a count control signal. A clock signal terminal of the switch is configured to input the clock signal, and the switch is configured to generate and output a data caching control signal according to the input count control signal and clock signal. A data signal input terminal of the first latch is configured to input a data signal. The first latch is configured to latch the data signal according to the data caching control signal input from the control terminal of the first latch. An output terminal of the first latch is configured to output the data signal.

    Abstract: The present disclosure proposes a micro power generation device including a plurality of generators stacked one above the other. Each of the plurality of generators includes: an upper electrode and a lower electrode spaced up and down; a spacer provided between peripheral edges of the upper electrode and the lower electrode; an upper friction material layer provided on a side of the upper electrode facing the lower electrode; and a lower friction material layer provided on a side of the lower electrode facing the upper electrode. The upper friction material layer, the lower friction material layer and the spacer together form a cavity. An intermediate spacer is provided between each adjacent two generators, each adjacent two generators and the intermediate spacer together form an intermediate cavity, and the intermediate cavity is filled with gas. A cavity of an upper one of any two adjacent generators communicates with the intermediate cavity between the two adjacent generators.
