Connected care transforms healthcare with rapid growth in wearable and hospital technology

A year after Jim Carroll’s ‘Human Technology Integration’ megatrend was outlined, market data shows rapid advances in wearable medical devices and hospital digital systems are reshaping healthcare, moving beyond speculation to real-world operational impact.

A year after Jim Carroll set out his “Human Technology Integration” megatrend, the case for it looks less speculative and more operational. Carroll argues that the most important shift is not a futuristic brain implant but the wider spread of connected devices already embedded in everyday care. That framing is reinforced by market data showing wearable medical devices grew to $68.1 billion in 2026 and are projected to reach $330.5 billion by 2033, far ahead of the $37.4 billion Carroll said he expected by 2028.

The broader wearable technology market is also expanding quickly, with wrist-worn devices still dominating. Grand View Research estimates the category at $103.1 billion in 2026, rising to $229.9 billion by 2033, while wrist wear accounted for 51.4% of revenue in 2025. The same report says North America held a 33% share of the market in 2025, underlining how much of this shift is being driven by health monitoring, not novelty electronics.

The hospital side of the trend is moving just as quickly. Stryker has launched its SmartHospital platform, describing it as a digital system designed to connect devices, data and care teams across clinical settings. UChicago Medicine has also moved ahead with a smart hospital rollout with Artisight, installing more than 1,800 devices across operating rooms, patient rooms and post-anaesthesia care units, including in a new 575,000-square-foot cancer facility.

That matters because the business case is no longer theoretical. Carroll says wearables could reduce hospital costs by as much as 16% over five years and remote patient monitoring could save the health system $200 billion over 25 years. Independent market forecasts point in the same direction, with one analysis projecting the wearable medical devices market at $523.58 billion by 2035 and another estimating $153.53 billion by 2033, both driven by chronic disease management, home-based care and rising demand for continuous monitoring.

Drug delivery is starting to reflect that shift too. Carroll points to Medtronic’s FDA clearance for its MiniMed Go app in January and Insulet’s February launch of an automated insulin delivery system in the Middle East as examples of connected monitoring moving into real-world treatment. Neural interfaces remain the smallest part of the story: Neuralink has expanded its trial, and China approved a commercial brain-computer interface device in March, but there is still no commercially available BCI in the US. On Carroll’s own evidence, the headline is less about implants than about the everyday infrastructure of connected care.
