Embedded Technology Integrated into an ECG Device
THE SCENARIO:
Embedded electronics have never been so popular within the design of new products, especially when operators require touch screen technology for interaction and quick start operation. Based on this "mobile phone" style approach, customers in the medical market have started requesting new features for their devices, including capacitive touch screens, modern Graphical User Interfaces and Wi-Fi capabilities for remote control and monitoring.
THE CONTEXT:
One of the key medical areas where this technology is being utilised is in the design of ECG machines. Also known as an electrocardiogram or an EKG, an ECG is a test that detects and records the strength and timing of the electrical activity in your heart. ECG devices are available across the entire healthcare system, and the very latest ECG devices have been designed to take advantage of the availability of new technologies including advanced GUI interfaces, capacitive touch screens, Wi-Fi and 4G communication and cloud-based platforms.
Thanks to these advances in technology it is now possible to rent ECG devices and pay only for the reports, enabling small medical offices and pharmacies to have access to accurate and cutting-edge devices. In order to reach this optimum level of access, it is fundamental to integrate within the device not only the capability to monitor the heart activity accurately, but also to communicate the data safely.
DAVE Embedded Systems' KEY ROLE:
DAVE Embedded Systems, thanks to its significant experience in designing and developing embedded systems, has proven expertise in all these areas giving them the capability to propose complete solutions for both physical devices and cloud interaction. DAVE Embedded Systems' specific knowledge in this industry includes the ability to
propose the right System On Chip (SoC) solution, and using this as a basis they can design and develop a system able to support a rich and modern user experience including Wi-Fi or 4G connectivity, which provides access to the cloud through secure certificates and secure boot.
