What is inflammation and the steps in the process of inflammation? We often feel redness, heat, swelling and pain at the site of wounds.

With a little electrical help from the human body, touchscreens can tell where our fingers are pointingâ¦. Touchscreens have used a variety of techniques over the last two decades to detect the placement of a finger on a screenâranging from mechanical, optical, and electrical sensing. Todayâs capacitive electrical touchscreens have proven to be the most versatile and efficient way to sense human touch.
