Until recently, sensing has been implemented using hardwired circuits, which can be inconvenient to deploy in the areas where they are mounted. To simplify deployment, next-generation sensors are transferring the data they record using wireless technology. A microcontroller that can interface with sensors and also has wireless capabilities makes continuous monitoring of received data possible. This article explores the technology involved in interfacing of sensors for medical applications, using hospital beds as an example. Hospitals are places where all of us have felt the need for a little more comfort, and hospital beds/mattresses can be made more comfortable through technological improvements possible using sensors and microcontrollers. Making patients more comfortable helps the patients, doctors, and also medical caretakers. To read more, click the download link above, or visit Embedded.com.
