As an important branch of neurological rehabilitation, facial palsy treatment is undergoing unprecedented changes. Nanochap has revolutionized facial paralysis stimulation devices with its innovative ENS001 programmable universal stimulation chip.

The revolutionary application of the Nanochap ENS001 chip.

The introduction of the Nanochap ENS001 chip has revolutionized the face of facial palsy stimulation devices, bringing a completely new solution to the treatment of facial palsy:

• Highly integrated and programmable: The ENS001 integrates an ARM Cortex-M0 MCU, a configurable boost DC converter, and a multi-channel highly flexible stimulation driver circuit. Through the dedicated programming interface, users can flexibly configure and adjust the operating parameters of the chip, such as stimulation waveform, frequency, pulse width, amplitude, etc., according to the specific treatment needs, realizing the fine control of electrical stimulation output.

• Enhance precision and stability: ENS001 adopts constant current source technology, which can control the stimulation current more stably and ensure that the current waveform remains relatively stable after entering the human body. Compared to traditional constant voltage source technology, this greatly reduces the risk of damage to surrounding tissues.

• Wide choice of stimulation waveforms: ENS001 supports a wide range of stimulation waveforms optimized for different types of facial paralysis based on extensive clinical research and practical experience.

• Wide application potential: Thanks to the highly integrated and programmable nature of the ENS001, facial palsy stimulators equipped with the chip are not only suitable for facial palsy treatment, but can also be expanded to include neurological rehabilitation, pain management, and treatment of psychological disorders.

Limitations of Traditional Facial Palsy Stimulator

1. Traditional facial palsy stimulators mainly rely on low-frequency pulsed current to stimulate facial muscles to promote local blood circulation and relieve muscle tension and spasm, thus achieving certain therapeutic purposes. However, such devices tend to have several significant limitations:

2. Fixed parameters and lack of flexibility: the stimulation parameters (e.g. waveform, frequency, pulse width, etc.) of traditional facial palsy stimulators are usually preset and non-adjustable, making it difficult to meet the individualized treatment needs of different patients.

3. Limited precision: Due to technical limitations, traditional devices may not be precise enough in current control, waveform generation, etc., which may affect the therapeutic effect.

4. Limited scope of application: Traditional facial palsy stimulators are mainly used for mild facial palsy symptoms, and their efficacy is often limited in severe or complex cases.

Comparison Summary

Compared to traditional facial palsy stimulators, the Nanochap ENS001 chip offers significant improvements in the following areas:

• Personalized treatment: Through programmability, flexible adjustment of treatment parameters is achieved to meet the individual needs of different patients.

• Precision and Stability: The adoption of constant current source technology improves the precision and stability of current control and reduces the risk of treatment.

• Abundant waveform choices: Supports a variety of optimized design of stimulation waveforms for precise treatment of different types of facial paralysis symptoms.

• Wide application potential: not only limited to facial paralysis treatment, but also can be expanded to a number of medical fields, bringing benefits to more patients.

The application of Nanochap ENS001 chip in facial paralysis stimulator is a major breakthrough and innovative upgrade of the traditional technology. It not only improves the therapeutic effect and safety, but also expands the application scope of facial paralysis treatment, injecting new vitality into the development of neurological rehabilitation field.
