Researchers Find a Hidden Cost to the Internet
Proverbs 18:24
"A man that hath friends must shew himself friendly: and there is a friend that sticketh closer than a brother."
Have you been on the internet lately? If so, it may be costing you more than you think. That's the suggestion of a study done by researchers from Carnegie Mellon University in Pittsburgh. The study...

Electric Skin

Job 42:2-3
"I know that thou canst do every [thing], and [that] no thought can be withholden from thee. Who [is] he that hideth counsel without knowledge? therefore have I uttered that I understood not; things too wonderful for me, which I knew not."

It's weatherproof, as flexible as paper, can generate electricity, serve as a microphone or radio speaker, sense your presence, act like a sponge and has some abilities that are like human skin. What could this strange material be? It's a plastic called PVDF.

PVDF has so many amazing abilities that one scientist remarked, "God was good to us." Those Electric Skinautomobile stickers saying, "unleaded fuel only" are made of PVDF. It has also been used to coat skyscraper surfaces to protect them from the weather. If you attach a few wires to the film, it will serve as a microphone. Or if you attach a speaker wire to it, it will serve as a speaker. It can sense weight, movement and infrared radiation. When bent, it generates electricity. If 220 tons of the material was formed into sheets that can be moved by sea waves, it would generate one megawatt of electricity.

It is this ability to generate electricity that makes it like your skin. Human skin and PVDF both act like an electric sponge. When you push on the sponge, electricity flows out just like water. When you release pressure on the sponge, electricity flows back in, just as water is soaked up by a sponge. Not only does this help us feel things on our skin, but also PVDF can be used in the same way to give machines the ability to feel things they touch.

The abilities of PVDF are amazing scientists. Yet its abilities are much less significant than the abilities of the skin that God has given us.

Prayer: 
Lord, I am surrounded by so many of your blessings, I cannot think of them all, no matter how long I try. I thank You and ask that I would continue to grow in my ability to see Your wonderful handiwork. Amen.
