Electrochemical oxidation (ECO) processes are energy intense systems as they mostly run under continuous constant current supply mode.
The experimental setup for accelerated corrosion under constant current is similar to that used for constant voltage except that the power supply is replaced by a constant current power supply.
The on-chip pump can also be readily used as constant flow sources (equivalent to constant current supplies for electronic devices) for routine microfluid manipulations on LOC devices.
As in manual SMAW, a constant current welding power supply is used, with either negative polarity direct current or alternating current.
Shielded metal arc welding equipment typically consists of a constant current welding power supply and an electrode, with an electrode holder, a ground clamp, and welding cables (also known as welding leads) connecting the two.
Centralized ADC units connected out to field devices supplying a constant current over copper twisted pairs.
The LED luminaire was powered by using either adjustable current supply (200 340 mA) or a constant current driver (350 mA) throughout the experiments.
A typical current strength in the order of 100 μA is supplied by a constant current source integrated in a digital multimeter Keithley 2000.
The sensor was biased by a constant current of 17 mA (Isens, Figure S1, Supporting Information), supplied by a constant current generator circuit implemented directly on the acquisition device.
