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.

Article Snippet: The hardware module contains a signal processing module, an electroporation module, and a data acquisition card (DAQ) module (Model USB-6343 from National Instruments Inc.).

Figure Lengend Snippet: Performance test of the electrical signal recording and electrical pulse regulating system. (A) Bode plot of the signal processing circuit. (B) Deviation of the pulse amplitude generated by DAQ. (C) Deviation of the pulse frequency generated by DAQ. In actual experiments, the frequency range of the electroporation pulses is 10–100 Hz, so the commonly used frequency points are selected for testing. (D) Deviation of pulse width generated by DAQ. (E) SNR comparison between shield box and no shield box. (F) Sensor performance test of NPMEA with PBS (Curves in different colors represented all 32 channels of a sensor).
