Nanochap Programmable Universal Stimulation Chip Stim Engines Series ENS001 on Microcurrent Tinnitus Treatment Device
Driven by modern medical technology, microcurrent therapy has become an important means of non-invasive treatment for a variety of diseases. Among them, microcurrent tinnitus treatment instruments（microcurrent tinnitus treatment devices） as a new type of tinnitus treatment, is gradually by doctors and patients more and more attention and try. The addition of Nanochap's programmable universal stimulation chip, Stim Engines Series ENS001, provides strong technical support to improve the performance of the microcurrent tinnitus therapeutic instrument and optimize the therapeutic effect.
Stim Engines Series ENS001 is a highly integrated programmable current stimulator with a very different design concept from traditional circuit boards. Through the Current Mirror architecture, the chip uses a current source and current absorber to form a push-pull mechanism capable of generating multiple channels of completely independent (isolated) charge-balanced biphasic waveforms. This waveform not only does not damage tissue, but also does not corrode electrodes, ensuring long-term safety. At the same time, the current amplitude of ENS001 is controlled by a "DAC-like" digital topology, which realizes high-precision regulation and provides a solid foundation for various nerve/muscle stimulation applications.
The application of ENS001 plays a crucial role in the microcurrent tinnitus therapy device. Microcurrent Tinnitus Therapeutic Apparatus stimulates the percutaneous vagus nerve in the external auditory canal through microcurrent to regulate the excitability of the cerebral cortex and reduce the dominance of sympathetic nerves in a non-implantable form, and the ENS001 chip's programmability enables the therapeutic appliance to accurately control the stimulation parameters of the microcurrent, such as the current intensity, the frequency of stimulation, and waveforms, to meet the personalized needs of different patients.
It is worth mentioning that ENS001 chip also integrates ARM processor, LCD screen driver, multi-channel arbitrary current stimulation engine and other modules, which makes the micro-current tinnitus therapy instrument with higher intelligence and convenience. Doctors can intuitively understand the parameters of the treatment process and patient feedback through the LCD screen, so as to adjust the treatment program in a timely manner. At the same time, the support of multi-channel arbitrary current stimulation engine makes the instrument able to stimulate multiple parts at the same time, which improves the treatment efficiency.
In addition to the technical advantages, the utilization of ENS001 chip in the microcurrent tinnitus treatment instrument also brings significant improvement in treatment effect. By precisely controlling the stimulation parameters of the microcurrent, the device is able to more effectively regulate the excitability of the cerebral cortex and reduce tinnitus symptoms. At the same time, the non-implantable treatment also avoids the risks of surgery and the pain of the recovery period, allowing patients to return to normal life faster.
