ifingi Enhances Conductivity

Conductivity is measured by a material’s ability to pass an electrical current.

Capacitive touch screens, like the screens used on the iPad, tablets and other touch-sensitive devices, work by sensing an electrical impulse at the point(s) of contact from your fingertip. Our skin carries an electrical charge and is conductive. If you were to use a wooden or plastic chopstick on a touch screen it would not work because wood and plastic are not conductive, and the electricity from your skin does not pass through the chopstick.  If you were to use a stylus on a touch screen it works because a stylus passes the electricity from your skin through the stylus and to the touch screen.

The primary factor influencing skin’s conductivity is moisture.

The more moisture in your skin the more conductive it is. Conversely, the drier your skin, the less conductive. A secondary factor influencing skin’s conductivity is temperature. As temperature decreases so does conductivity. It follows that the responsiveness of a touch screen is dramatically impacted by the condition and temperature of the fingertip.

For many occupations, dry hands are just part of the job.

Healthcare workers for one, are constantly washing or sanitizing their hands. Many others are exposed to harsh weather that may make their hands dry and callused. A simple solution is to apply hand creams and moisturizers, though this doesn’t really help the person using a touch screen. The screen gets dirty more quickly and then the smudges start to impede the conductivity of the screen. It appears to be a ‘lose – lose’ situation.

Cold fingers impact the conductivity of the skin and the responsiveness of touch screens.

Hand warmers, rubbing hands together, putting hands in armpits or under legs are all good temporary solutions to cold hands. Unfortunately these are temporary solutions to chronic problems. Consider that countless people suffer from diabetes and blood circulation conditions that leave their hands cold all the time.

Long fingernails pose a significant hurdle to conductivity.

People with long fingernails have to adjust the way they contact a touch screen because fingernails are not conductive. That’s right, long fingernails looks great but don’t work great. Typically we see people with long fingernails using the pad of the finger,not the fingertip on touch screens. A simple solution would be to cut the fingernails, though it’s not likely people would give them up.

Many things can and do impact the conductivity of our skin on touch screens.  As outlined above, there have previously been no real, simple, acceptable solutions to the conductivity problem until now – ifingi is the solution. The special material in ifingi enhances conductivity so that cold, dry hands and long fingernails no longer impede the use of your touch screen tablet.

ifingi enhances the skin’s conductivity significantly more than natural skin.
