The platform revolutionizes well being and health know-how evaluation, effectively monitoring movement, temperature, and biopotentials and adapting to future improvements.
Maxim creates subtle options for medical and superior health industries, primarily from its numerous product strains. To expedite buyer analysis of those options and help with their design processes, Maxim launched the “hSensor” platform. This built-in sensor platform permits clients to shortly and simply assess Maxim’s software choices. It’s additionally designed to be adaptable, integrating upcoming options, whether or not at the moment in design or deliberate for future improvement.
The hSensor platform is provided to deal with an array of measurements crucial to healthcare and health applied sciences. These embody movement monitoring, exact pores and skin temperature measurement, and varied biopotential assessments reminiscent of electrocardiography (ECG), electromyography (EMG), and electroencephalography (EEG). Moreover, it helps a number of reflective photoplethysmography measurements like pulse oximetry and coronary heart charge detection, using three wavelengths: 880nm (infrared), 660nm (pink), and 537nm (inexperienced).
For health functions, the platform accommodates chest-based techniques reminiscent of chest straps geared up with coronary heart charge (HR) displays and people who mix HR with electrocardiography (ECG). Wrist-based functions embody smartwatches with optical HR sensors. Moreover, ear-based functions, reminiscent of headphones built-in with optical HR monitoring, are supported.
The platform can be utilized in scientific settings for chest-based functions like 1-lead ECG patches designed for arrhythmia detection, which observe each ECG and HR. It additionally helps pores and skin temperature measurements. Finger-based functions on the platform embody optical SpO2 measurement, and each ear-based and head-based functions can measure optical HR and SpO2. Lastly, arm-based functions are lined with armbands that incorporate ECG capabilities. These versatile functions spotlight the platform’s broad adaptability in monitoring and diagnostic contexts.
The platform is suitable with GUI functions on each Home windows-based PCs and Android gadgets, facilitating accessible knowledge assortment and visualization. It helps a direct USB connection by way of a USB Kind-C connector and Bluetooth Low Vitality (BLE) for configuring and gathering knowledge. Moreover, the platform gives a direct-to-flash reminiscence mode for knowledge assortment, which might learn flash reminiscence by way of a USB connection.
On the coronary heart of the hSensor platform is the MAX32620 microcontroller. This method is provided with a variety of sensors, together with the MAX30003/MAX30004 biopotential analogue front-end (AFE) for biopotential measurements, the MAX30205 sensor for human physique temperature, and the MAX30101 for pulse oximetry and coronary heart charge monitoring. It additionally consists of the LIS2DH 3-axis accelerometer, the LSM6DS3, which mixes a 3D accelerometer and a 3D gyroscope, and the BMP280 sensor for measuring absolute barometric strain. These elements collectively improve the platform’s functionality to watch varied well being parameters effectively.
