Understanding Closed Loop Systems

A closed loop system, also known as an automated feedback control system, consiss of three essential considents: a sensor to collect phyological data, a procesor to analyze that data againtt predefinited targets, and an actuator to deliver a corrective action. In avable and miniaturized formats, these actuments are integrated into compact hous that can be worn body as patches, wristbands, or even implanted subcutanously.

How They Differ from Open Loop Devices

Traditionall open lop medical devices, such a a standard insulin pump, require the user to melyure their glucose level and manually program thee pump to deliver an applicate dose.
