What's the Difference Between Square Wave and Sine Wave in PEMF Therapy?
One of the most common questions we receive is:
"Should I choose a square wave or a sine wave?"
The answer depends on your application.
Square Wave
✅ Rapid rise and fall time
✅ Fast magnetic field switching (high dB/dt)
✅ Strong stimulation effect
✅ Widely used in professional PEMF therapy systems
Because the magnetic field changes quickly, square waves can generate stronger electromagnetic stimulation, making them a popular choice for rehabilitation, recovery, and wellness applications.
Sine Wave
✅ Smooth and continuous waveform
✅ Gentle magnetic field transition
✅ Comfortable treatment experience
✅ Commonly used in low-intensity wellness applications
The magnetic field changes gradually, producing a softer and more natural stimulation.
Which is Better?
There is no single "best" waveform.
The right choice depends on:
• Treatment goals
• Magnetic field intensity
• Frequency settings
• Coil design
• Overall system engineering
At UTK Technology, we can develop both square wave and sine wave PEMF systems according to your product requirements, helping brands create solutions that match their target market.
