Most smartphones use a type of capacitive screen (Wikipedia) called “projected capacitance” or “pro-cap”. It’s a long story, but basically, it goes like this:
“When a conductive object, such as a finger, comes into contact with a PCT panel, it distorts the local electrostatic field at that point. This is measurable as a change in capacitance.
If a finger bridges the gap between two of the “tracks”, the charge field is further interrupted and detected by the controller. The capacitance can be changed and measured at every individual point on the grid (intersection).
Therefore, this system is able to accurately track touches.
Then there’s Nanotips. Claimed to be “the world’s first liquid solution that can make any glove touchscreen compatible”, it was a successful Kickstarter product that actually made it through to retail.
Nanotips is available in two versions: black for leather (or neoprene, Kevlar, Gore-Tex, rubber) gloves and blue (90% translucent) for cloth gloves.
It’s about as easy to use and takes as long to apply as reading this sentence. Shake, apply and dry. It disappears into the black leather, so you’ll never know it’s there.
Apparently, it has some kind of nano (nanotechnology) particles that give it the capacitance needed to drive a touchscreen.
It smells like — and looks like — black nail polish (not that I’ve ever used any!) and it even has a brush applicator in the bottle.
Coat the entire fingertip and either let it dry overnight or hit it with a hair dryer (or the high-endSteinel Heat Gun (review) you bought from the webBikeWorld affiliate!) and you’re ready to rock that smartphone about 3 minutes later.
