Neck massager is widely used in daily life, it has become an important tool for many people to relieve neck fatigue and improve cervical spine health. With the advancement of technology, more and more innovative technologies are being applied to neck massagers, in addition to the common massage and hot pack functions, there is also pulse massage technology.

During the iterative process, pulse technology in neck massagers has gradually become is a key functional component that provides a massage effect by emitting pulsed currents to stimulate the muscles and nerves in the neck. This technology relies on a series of electrical impulses generated by a chip, so a chip containing pulse technology plays a critical role in a neck massager.

The Stim Engines Series NS4 Multi-functional Neurostimulation Chip is an advanced single-chip TENS/EMS current pulse device that delivers effective stimulation of the body's nerves and muscles by means of transcutaneous nerve/muscle electrical stimulation. This technology is not only highly integrated, but also has strong functionality expandability, providing strong technical support for the development of neck massagers.

The principle of Nanochap Nanochap Stim Engines Series NS4 in neck massager:

• A neck massager containing the Stim Engines Series NS4 chip generates sufficient energy for subsequent stimulation waveforms through the built-in boost module, which in turn generates a series of electrical pulse signals;

• These signals are regulated by an internal current source and delivered to the electrode pads;

• The electrode pads convert the electrical energy into magnetic energy and deliver it in the form of pulses to the cervical spine area of the body;

• When the magnetic energy reaches the tissues of the cervical spine, it is able to propagate gradually through the skin, muscles and nervous system to produce stimulation;

Stim Engines Series NS4 chip TENS current pulse device is different from the traditional pulse device can be more effective in stimulating the neck muscles and nerves, simulating a variety of simulation massage, to achieve the effect of deep relaxation of the cervical spine. The device is able to accurately target specific areas of the neck by adjusting the frequency and intensity of the pulses to provide a personalized massage experience for the user. At the same time, the electrical pulses sent by the TENS current pulse device are low-voltage and small-scale, and will not cause harm to the human body.

The NS4 chip's multi-modal stimulation module supports 3 major functions and 12 modes, providing a wealth of massage options for the Microcurrent Massage Belt. Whether it is for analgesia, muscle building or rehabilitation, users can choose the right mode according to their needs, thus realizing a personalized massage experience.

In addition, the NS4 chip also has a unique constant current source output and low standby power consumption technology. The constant current output ensures the stability of the current during the massage process, while the low standby power consumption allows the belt to save energy and prolong its service life when it is idle.
