a Transmission of the message “Hi” (ASCII: “1001000 1101001'') using the bit encoding illustrated in b. Bits “11'', shown in grey, are concatenated at the beginning to signal the start of a message and define the duration of the bit interval Tb and the duty cycle α. c Comparison of demodulated signals transmitted using the platform at different bit rates, achieved by applying different transmission speed factors N ranging from 1 to 8. d Evolution of the demodulated signal width Tw with the speed factor N. The black dashed line is the average evolution of the data presented, and the red dotted line is the proportional evolution with 1/N. Solution composition and flow rates are given in the Methods and Supplementary Note 6.4.
