Reference Design For Wi-fi Coronary heart Monitor

Texas Devices (TI) has launched a wi-fi coronary heart monitor reference design for battery-powered, 3-channel ECG purposes, providing correct monitoring and BLE connectivity.


Within the quickly evolving healthcare expertise panorama, wi-fi coronary heart displays have emerged as indispensable instruments in selling proactive well being administration and distant affected person monitoring. Because the world faces unprecedented challenges, together with the continuing international pandemic and a rising give attention to private well being and wellness, correct and handy coronary heart fee monitoring options have grow to be extra important than ever. Texas Devices (TI) has launched the reference design for a wi-fi coronary heart monitor with Bluetooth Low Vitality (BLE) to simplify the design course of. The reference design empowers the shoppers to create battery-powered, 3-channel well being and health electrocardiogram (ECG) purposes. With seamless integration into an iPhone Working System (iOS) Cellular Utility, customers can effortlessly monitor their coronary heart fee information. The machine is powered by a dependable Lithium-ion battery, guaranteeing prolonged utilization with out interruptions. Geared up with Electromagnetic Interference (EMI) filters built-in into the machine, it successfully rejects interference from exterior Radio Frequency (RF) sources, guaranteeing correct and reliable measurements. Moreover, the open-source Firmware and iOS software supplied with the design allows clients to expedite their time-to-market, making it a most popular selection for well being and health purposes.

On the core of the Wi-fi Coronary heart Charge Monitor lies the ADS1293 machine, which serves because the analogue front-end (AFE), and the CC2541 machine, functioning because the BLE system-on-chip (SoC). The design permits end-users to observe a affected person’s coronary heart fee information remotely. That includes three high-resolution channels, the AFE can function at a pace of as much as 25.6 kps. Together with EMI filters on all enter pins ensures dependable sign high quality. On the similar time, a versatile routing swap facilitates unbiased lead-off detection, proper leg drive, and Wilson/Goldberger reference terminal technology, eliminating the necessity for exterior lead reconnection. Furthermore, a fourth channel caters to exterior analogue tempo detection, catering to purposes that don’t make the most of digital tempo detection.

The SoC resolution caters to each Bluetooth low vitality and proprietary 2.4-GHz purposes. Its design permits the development of sturdy community nodes with minimal complete bill-of-material prices, making it an economical choice. This highly effective SoC integrates a number one RF transceiver with an industry-standard enhanced 8051 MCU, in-system programmable flash reminiscence, 8-KB RAM, and quite a few supporting options and peripherals. The SoC options ultralow energy consumption.

The ECG information transmission makes use of a burst of six BLE notification packets each 14 ms. Every notification packet includes 20 bytes, encompassing important data similar to ECG Pattern 1 and ECG Pattern 2, comprising uncooked Analog-to-Digital Converter (ADC) information for 3 channels. Moreover, an ECG error or standing packet is shipped after each 17 ECG samples, containing a 2-byte working counter, a standing packet starting indicating a 7-byte error standing, and a standing packet finish.

TI has examined this reference design. It comes with a Invoice of Supplies (BOM), Meeting drawing, Gerber recordsdata, PCB structure, schematics, and so on. Yow will discover further information concerning the reference design on the corporate’s web site. To learn extra about this reference design, click on right here.
