Fig. 5: Numerical indicator based on bistable ERPC.

a schematic diagram of the numerical indicator composed of seven parts of independently controlled SiO₂/PCb-PEG-EG ERPC (30/60/5/5 vol%); b the voltage profiles of Channel 1–7 for the sequent display of ten digits; c displaying the digits from 9 to 0 in the absence of E-field.
