The Types segment classifies fetal activity monitors by underlying sensing technology and form factor, revealing distinct value propositions and cost structures. Doppler‑based devices, which emit ultrasonic waves to capture fetal heart motion, dominate the clinical‑grade market with an estimated 40 % share due to their proven accuracy and integration with hospital information systems. Accelerometer‑based wearables, typically integrated into belts or patches, account for 35 % of sales; they offer continuous, non‑invasive monitoring suitable for home use and generate data streams compatible with mobile health platforms. Handheld units, combining a simplified Doppler probe with a smartphone interface, represent 15 % of the market, appealing to low‑resource settings where portability and ease of training are critical. Finally, AI‑enhanced analytics modules, sold as software add‑ons to existing hardware, capture the remaining 10 % and reflect a shift toward predictive analytics that can flag potential complications earlier. By delineating these technology‑based types, the market taxonomy clarifies investment focus areas, as manufacturers prioritize sensor miniaturization and data‑fusion algorithms to sustain growth across both clinical and consumer segments.
