Technical details and manufacturing context for Physiological Sensor Array

Definition

A physiological sensor array is a critical component within medical monitoring devices that integrates multiple specialized sensors to capture, process, and transmit real-time data on vital signs and other physiological parameters. It functions as the primary data acquisition interface, enabling comprehensive patient monitoring in clinical, ambulatory, and remote healthcare settings. The array typically comprises electrodes for electrical activity (e.g., ECG, EEG), optical sensors for blood oxygen saturation, and pressure transducers for force or pressure measurements. These sensors are mounted on a flexible polyimide substrate and encapsulated with medical-grade silicone and epoxy for biocompatibility and protection. The analog signals from each sensor are conditioned through amplification and filtering, then digitized by an analog-to-digital converter (ADC) with a resolution of 16 to 24 bits. A microcontroller or system-on-chip processes the digital data, which is then transmitted via USB 2.0/3.0 or optional Bluetooth to a host device for display, analysis, and storage. The array supports 8 to 32 channels, with sampling rates from 250 to 1000 Hz per channel, and offers high input impedance (≥10 MΩ) and common mode rejection ratio (≥100 dB) to ensure signal fidelity. It operates within a temperature range of 0–45 °C and can be stored between -20 and 60 °C, with relative humidity limits of 10–90% non-condensing. The device is rated IP22 to IP44 for dust and water resistance, powered by 3.3–5 V DC, and consumes 0.5–2.5 W depending on active channels and sampling. Its compact design, weighing 200–500 g and measuring 100×60×20 to 150×80×30 mm, makes it suitable for portable monitoring. Always verify model-specific specifications and applicable standards with the legal manufacturer or supplier before procurement or use.

Working Principle

The array operates by utilizing individual sensors (e.g., electrodes, optical sensors, pressure transducers) to detect specific physiological phenomena (electrical activity, light absorption, force). These analog signals are conditioned (amplified, filtered), digitized by an analog-to-digital converter (ADC), and processed by a microcontroller or system-on-chip (SoC). The processed data is then formatted and transmitted via wired or wireless interfaces to the host monitoring device for display, analysis, and storage.
