Figure Lengend Snippet: The hardware of the DMFcontrol system included three operation layers: DMF chip holder (top layer), field-programmable gate array (FPGA) board (FPGA, mid layer) and control electronics board (PCB, bottom layer) and The DMF chip holder was to mount the DMF chip. The control electronics on the printed circuit board (PCB) was used to apply driving voltages (acquire capacitance information) to (from) the DMF chip. The FPGA acquired the signal from the control electronics and transferred it to the computer. The IC testing clips connectwed the DMF chip to the control electronics. The relay array and multiplexers switched the DMF chip between the driving voltages (actuation) and oscillator (sensing).
