A wristband is simply used to ground the body since the unit is so cheaply made the unit itself is not grounded. This is a marketing gimmick when the say it is ‘to complete the circuitry’ or ‘stimulate the upper body’.
The wrist bands are designed to prevent the destruction of CMOS devices. (CMOS is the deposition of doping and etching of a Metal Oxide on Saphire device, in short an Integrated Circuit). Most units on the market use TR (Transformer Rectifier) concepts in producing their output, this concept does not utilize CMOS substrate devices. We often build static as we walk and move, this is more pronounced if we are wearing anything nylon. The wrist band is conductive and conducts the static electricity from the body to ground. This prevents the charge from going through the CMOS device. If a charge goes through a CMOS integrated circuit, it can destroy it instantly, most often it damages it which causes a diminishing deterioration until the ultimate failure. During the “slow death” of the device performance becomes unreliable, unrepeatable then ultimately the device fails.
The conductive wristbands may or may not require any liquid or gel to add to the conductivity of the band to ground. This depends on the quality of the grounding strap and the wristband.
Most circuit designers “know their stuff” and design the circuits such that the input and output pins of the integrated circuits are connected into circuitry such that they are buffered from outside forces. Our units have the proper buffering so that stray voltages cannot and do not reach the components that can be affected by static. In addition the care of our unit is electrically connected to earth ground, this will direct any stray charge that even gets to the case to ground and protect the components as well.
The ground strap is a marketing gimmick. Think about it, your computers and cell phones have large scale integration in their operating systems and you do not wear a ground strap when working with either of them. Why would you need grounding for something as simplistic as the power supplies in a footbath? The control circuitry may have some active devices that can be damages as we do, but with proper configuration this can be protected
The wristband has nothing to do with the footbath process. The key to the ionic detox footbath is the ions from the salt & water that are interacting with your body, not the current or so called ‘circuitry’ that these companies claim. WE (Optimum detox foot baths) DO NOT USE WRISTBANDS since our unit has a chassis ground for all internal assemblies to stop any voltage potential ever being on the case
