Segmentation by types distinguishes four technological families that determine product differentiation and cost structure. Contact‑based detectors, such as ECG electrodes and pulse oximeter probes, represent the traditional core, commanding the largest volume due to their established clinical efficacy and integration with legacy systems. Non‑contact solutions, including infrared thermography and radar‑based respiration monitors, are gaining traction for infection‑control settings, contributing an expanding share of the market despite higher unit costs. Wearable devices—smart watches, patches, and textile‑integrated sensors—are reshaping consumer adoption patterns, driven by continuous monitoring demands and data‑analytics ecosystems. Implantable detectors, though niche, address long‑term monitoring for cardiac rhythm disorders and chronic pulmonary conditions, commanding premium pricing and specialized reimbursement pathways. The relative weight of each type reflects technology maturity, regulatory clearance timelines, and end‑user acceptance, collectively influencing the overall market valuation and investment priorities.
