That will generate a high voltage, extremely low amperage static electric buildup along the friction surfaces.
We’re talking about 4KV, 1.2 mJoules for 10-5 amp seconds.
Phone chargers contain 2400mAh of charge running 5 volts at 3A.
So somehow, you need to convert an ultrahigh voltage and minuscule amperage to a low voltage and relatively high amperage over an extended period of time. You’ll lose some energy in the conversion, and as a result, you’d have to have around 300 people feeding power into the charging circuit with their feet, over an extended period, to build up enough power for a measurable charge.
You’d do better to charge it using a stationary bike and a dynamo, which results in significantly less conversion loss. Or, for that matter, a swing dynamo that generates current from the swing of your walk (some old watches do this).
