Microchip’s innovative design for portable and accurate ECG heart monitoring applications
The electrocardiogram or ECG machine design from Microchip Technology is used to monitor and record the electrical activity of the heart.
This design features the SAML22, a high-performance, 32-bit Arm® Cortex®-M0+ microcontroller with ultra-low-power technology, the BTLC1000 Bluetooth® Low Energy (BLE) 4.1 module, the ECC508A Crypto Authentication chip, and the NeuroSky® CardioChip™ ECG biosensor.
Since each heartbeat produces an electrical impulse in the heart, the generated cardiac electrical potentials can be measured with sensors placed on the body at different locations. Abnormal electrical activity can indicate conditions such as heart attack, chest trauma, reduced blood flow to the heart, arrhythmia, or heart deformities. The ECG demo measures a complex heart rate and computes other heart-related data. Patient movement is also tracked via an on-board accelerometer. The BTLC1000 BLE module on this board allows the demo to communicate with tablets, smartphones, or PCs for IoT capability.
The demand for portable and accurate ECG monitoring has grown substantially. Despite the smaller size of these portable products, ECG devices still require precision filtering, high-performance processing power, and integrated high-resolution graphics control that is separate from the main microcontroller core.
