Invention of the Day 1

For the next two weeks there will be an invention per day, just as an exercise in keeping Lola occupied.

Today’s invention is a brain monitoring system.

The hardware is a set of in-ear headphones where the rubber earplugs contain microwires and thus also act as contact electrodes.

These headphones can be used as normal headphones for listening to music and making phone calls, but they can also be used to monitor brain signals.

A device, say a smartphone, will detect a brain signal under various conditions, say open circuit, DC and various frequencies of AC, over four quadrants of an IV curve assuming some power can be fed to the electrodes. Yada.

A detector in the phone will capture the return signal and do the signal processing.

An app will convert the signals into information that can be reported in graphs and riddles, and also used to sell stuff to the user based on their needs.

An example would be to correlate certain brain signals to stress and then use the app to flog vitamin B to the user.

If there aren’t any really useful brain signals it wouldn’t matter. People love mood stones after all.
