Nowadays current generators are used to control the delivery of electrical currents across the surface of skin to stimulate the nerves, this techniques used is known as Transcutaneous Electrical Nerve Stimulation (TENS). In this paper we are going to propose a TENS system which can be used to relieve any patient's muscular pain and sprain using electrical current. We attempt to generate two basic modes in TENS device which are conventional and burst patterns. The ADC and PWM functions in PIC18f4550 microcontroller have controlled the duty cycle of output. Specifically we describe the two main techniques in detail and further describe the fundamental principles for the use of TENS depending on each technique. Platform also focuses on increasing safety of the user.
