1. Apparatus for transcutaneous electrical stimulation in a user, said apparatus comprising:
a stimulation unit for electrically stimulating body tissue of said user using electrical pulses;
a sensing unit for measuring body temperature of said user; and
a control unit connected to said stimulation unit and said sensing unit, said control unit being configured to (i) record a first body temperature from said sensing unit before electrical stimulation; (ii) apply electrical stimulation at a first stimulation intensity for a period of time and monitor body temperature change from the first body temperature; (iii) automatically increase the stimulation intensity when the body temperature change is within a temperature change threshold; and (iv) determine an electrotactile sensation stimulation intensity of said user as the lowest stimulation intensity causing the body temperature change to exceed the temperature change threshold.
