If the accuracy of the work done by any gadget is precision, then the cost of manufacturing the gadget becomes directly proportional to it. This in turn decreases the end users affordability or adoptability to it.
In the coming decades, the quality of work will play the role in all the fields. Too considering the Medical field, the accuracy, time, precision, adoptability, user-friendly are all to be considered.
This parameters plays the most important to develop a gadget in Medical field. So these parameters measure the cost of the gadget developed. This directly increases the cost of usage to the end user.
As far as the embedded is in action, all the above noted parameters are brought into a single chip, too a tiny gadget which reduces the cost of manufacture, user friendly, adoptability, precision etc.
As the gadget is reduced in its size but maintaining the end result with most advantages then a machine, it makes the end users to use them at cheaper costs.
