Here is a simple capacitive touch switch circuit for electronics hobbyists. Even though the circuit uses smd components, construction of the touch sensor switch is not very hard because the whole ...

You can’t have a touch sensitive switch without a way to detect the presence of a finger! A touch sensor, especially a capacitive touch sensor, has some surprisingly sophisticated electronics to ...

A new sensor that mimics human touch is placed on a man's wrist to test the device's sensitivity. It is no longer science fiction, we really do have the technology to rebuild veterans who have lost ...
