In the field of health and comfort, neurostimulation technology is gradually changing the traditional medical equipment with its unique advantages. As a leading company in the field of neurostimulation chips, Nanochap Electronics Technology Co., Ltd. has released its multifunctional neurostimulation chip NS4, which is applied in the antiemetic bracelet, reflecting the powerful advantages of this technology.

Nanochap's multi-functional neurostimulation chip, NS4, is an advanced product that stimulates the human body's nerve thick fiber network and muscle tissues through biphasic currents to achieve a variety of physiological regulatory functions. the NS4 chip integrates a power switch, a high-voltage boosting converter, and a multi-modal stimulation module, which can be used to achieve a variety of functions such as massage and analgesia, assisted muscle building, and muscle rehabilitation through the adjustment of different pulse widths, intensities, and time intervals.

The working principle of the NS4 chip is particularly unique in the antiemetic bracelet. When the user wears the bracelet, the chip delivers weak but steady current pulses to the nerve areas associated with nausea and vomiting through Transcutaneous Electrical Nerve Stimulation (TENS) technology. This current stimulation inhibits the over-excitation of the nervous system, which reduces the feeling of nausea and even achieves an antiemetic effect.

The core technical advantages of NS4 chip in antiemetic bracelet are mainly reflected in the following aspects:

- Highly integrated, low power consumption: NS4 chip adopts highly integrated design, which makes the size of the bracelet more compact and convenient for users to carry.

- Personalized stimulation adjustment: NS4 chip supports a variety of stimulation modes and intensity adjustment, users can personalize the settings according to their own physical condition and the degree of nausea, so as to more accurately meet their needs.

- High safety: NS4 chip adopts biphasic constant current source stimulation, the current output is more stable and not affected by resistance, while the high degree of charge matching reduces the risk of charge imbalance inside the human body and ensures the safety of use.

- Remarkable effect: Compared with traditional antiemetic methods, NS4 chip acts directly on the relevant nerve area through nerve stimulation technology, which has a faster onset of action and a more significant effect.

Compared with traditional antiemetic devices, the application of NS4 chip in antiemetic bracelet has significant advantages. Traditional antiemetic devices usually use drugs or physical pressure to relieve nausea and vomiting, which are effective to a certain extent but often have side effects or inconvenient to use. For example, drugs can cause allergies or dependence, while physical pressure requires the user to apply constant pressure, which makes it inconvenient to use.

In contrast, the NS4 chip can stop vomiting through neurostimulation without the need for drug intervention, avoiding potential side effects. At the same time, its small size and convenient use greatly improve the comfort of the user. In addition, the NS4 chip also supports personalized stimulation adjustments, which can be precisely set according to the user's actual needs to ensure that the best results can be achieved every time the device is used.

In addition to antiemetic bracelets, the NS4 chip has a wide range of applications. It can be used in a variety of products such as smart massage patches, large-scale physical therapy devices, nursing beds, massage chairs, etc., helping to realize miniaturized, low-cost, low-power solutions.
