The current development of smart medical devices must be seen in the context of the need to reduce healthcare costs, especially now that population aging has become a healthcare management issue for societies around the world. The issue has both social and economic dimensions, raising the awareness that modern technology can enable health care workers to perform a variety of routine health monitoring remotely, meaning that many patients can remain at home, saving significant resources. This trend towards remote diagnostics is driving the demand for portable/wearable smart medical devices. In terms of its electronic components, this means miniaturization.
