Figure Lengend Snippet: Design of integrated electric signal recording and electric pulse regulating system. (A) The system structure of integrated electric signal recording and electric pulse regulating system: biosensor units, hardware module, and software module. The hardware module includes a signal processing module (blue), electroporation module (orange), and a DAQ module (green). The functions of the software module include waveform display, data storage and pulse control (pink). (Numbers in parentheses indicate the corresponding labelled components in (B,C) ) (B) Signal processing module (integrated 32-channel signal processing circuit) diagram. (C) Electroporation module (integrated 32-channel electroporation circuit) diagram. (D) The software user interface of integrated electrical signal recording and electrical pulse regulating system. (E) The internal wiring of the shielding box. The ground wire of the shielding box is connected to the ground of the power supply, which can effectively shield the interference of power frequency noise and high frequency noise. (F) The photo of the integrated electrical signal recording and electrical pulse regulating system.
