To make people aware of not having the ability to sense the touch and prevent them from physical injuries or risks is a difficult task.


The Numb Aid comprises the feature of measuring the sense of touch using ESP32 GPIO capacitive touch sensor pins.

The second feature includes the display of the status of LED where, LED remains "on" when the object( containing the system) comes in contact with the body, it changes to "off" when there is no contact in between.
