Nanochap EPC001 Chip in AED, Miniaturization Greatly Reduces the Product Volume, Saving Three-fifths of the Circuit Area

Automated External Defibrillator (AED) is widely used as an emergency rescue device during cardiac arrest. It can restore normal heartbeat through electric shock and provide timely support for cardiopulmonary resuscitation (CPR). However, the traditional AED defibrillator is inconvenient to carry and difficult to operate due to its large size and complicated and numerous circuits. In order to solve this problem, the innovative use of Nanochap's EPC001 chip in AED defibrillators has realized a miniaturized design that greatly reduces product size and saves three-fifths of the circuit area.

The Nanochap Nine Senses EPC001 chip is an innovative Vital Signs Parameter Detection Chip that can efficiently process complex electrical signals and sensor data. In AED defibrillators, this chip takes full advantage of its high performance and versatility to achieve a miniaturized product design.

First of all, the Nanochap Nine Sensors EPC001 chip realizes the compression of the originally bulky AED circuitry through the optimized layout and integration of internal circuits. Traditional AED defibrillators usually use MCU + peripherals, the circuit is usually complex and cumbersome, occupying a lot of space. With the Nanochap EPC001 chip, which integrates a high-precision EEG/ECG/EMG/PPG analog front-end and a powerful RISC-V MCU, the streamlined and highly integrated circuitry reduces the overall circuit area by three-fifths, greatly reducing the size of the product.

Secondly, the high integration and low power consumption of the Nanochap EPC001 chip have changed the design of traditional AED defibrillators. In the past, in order to realize complex electrical functions and signal processing, multiple circuit boards were required, which led to the huge size of the whole device. Now, the highly integrated and low-power design of the Nanochap Nine Sense EPC001 chip makes it possible to realize complex functions with only one chip. As a result, the size of the entire AED can be greatly reduced, improving portability and operational efficiency.

In addition, the Nanochap EPC001 chip has excellent anti-interference and signal processing capabilities and is able to accurately recognize the electrical signals of cardiac arrest. In this way, the AED can respond quickly and correctly to determine the patient's heart condition, providing accurate and effective CPR support for patients with sudden cardiac arrest.
