Thus, developing and executing strategies that optimize the learning process is the utmost importance to provide to the students some skills as pro-activity. Emphasizing the need to develop equipment for the improvement of medicine and biological sciences in general, we have that, acquire equipment capable of contributing to the technological evolution in the medical field has been comprehensive, because the advances of biological systems and apparatus that help the health professional became common worldwide. However, in general, medical equipments are really expensive. In view of this problem and

3 261 the need for a new technological approach, a search was made to find some economically viable components in order to make easier the access for some professionals interested in technologies which could turn the diagnoses more fast and effective. With this project, we intend to explore several concepts of courses from the Biomedical Engineer department of UFPA (Universidade Federal do Pará), as well as to encourage the knowledge and development of new technologies. This article presents a prototype of a low cost neonatal incubator coupled to a newborn body temperature monitoring system from an android mobile application. The prototype was developed by a software, it has been tested and it follows some technical standards of installations and works from a dome made of acrylic with several intelligent sensors such as temperature and humidity (DHT11), piezoelectric sensor and sensor Of skin, those sensors contribute to increase the incubator s performance. The control of these sensors is made by a Arduino platform which is currently considered easily accessible for the creation of projects and prototypes for the insertion of knowledge in Engineering. In addition, the Arduino enabled the monitoring process in a simplified way, a example of that is the creation of mobile applications in the Android language. For monitoring, the knowledge about the temperature of a newborn is extremely important because the baby needs a specific care, such as reading of weight and monitoring of temperature and pulse, which must be done constantly. The neonatal incubators for newborns are essential for this

Keywords: Neonatal Incubator, Health Technology, Low Cost Prototype, Arduino, Engineering Education About low cost neonatal incubator The use and creation of health technology have big importance for the realization of the comprehensive activities in health field, encompassing a set of skills to promote the health, rehabilitation, prevention and treatment of diseases. In this perspective, a multi-professional presence is so important, being one of the main the engineer, in special the Biomedical Engineer. Like this, this work s objective is to show a low cost neonatal incubator with a temperature monitoring system from an android mobile application, idealized by UFPA s Engineer Biomedical graduating. The project was direct for a conception of an incubator because of the equipment importance on neonatal field. Since this is a device specially designed to provide the newborn ideals when suitable conditions when have difficulty adapting to the external environment.

5 25.2. Methods 263 For monitoring, the knowledge about the temperature of a newborn is extremely important because the baby needs a specific care, such as reading of weight and monitoring of temperature and pulse, which must be do constantly. The neonatal incubators for newborns are essential for this process; therefore, the development of the low cost prototype aims to make the measurements minimally invasive for the newborn, which helps in the treatment and recovery Methods The project was developed for a neonatal assistance to offer a low cost incubator that offer technologies to facilitate the newborn monitoring, diagnosed by temperature e humidity (DHT11), skin sensor. The monitoring will be made by an Android Mobile application. A software developed the prototype, it has been test and it follows some technical standards of installations and works from a dome made of acrylic. This information is essential for monitoring the neonatal while in the incubator Design software on 3D A software was use, a 3D modeling platform made the acrylic dome vision possible and the sensor storage. This sensor was severally important to a newborn monitoring on the low cost incubator, because sensor was necessary for

For temperature and humidity control, DHT11 (controlled by Arduino platform) was use to read temperatures and humidity. In practical terms, Arduino is a little computer programed to process inputs and outputs between device and the components connected to it 1. The internal circuit make the sensor readings and communicate with Arduino. Especially designers and artists that want to create easily prototype, but do not need a deep understanding about the technical details behind your creations 1 use the Arduino in so many educational programs around the world. Besides that, a LCD monitor 16x2 is also part of the assembled circuit; its objective is to reach the reading of the circulating temperature for the newborn and to assist the health professional so that he is aware of the temperature control of the newborn. In picture next, this is a software of incubator and your system control built for arduino platform. The Figure 25.1 shows the incubator and your system control built for Arduino. The Figure 25.2 shows the prototype incubator on software and the Figure 25.3 shows the 3D APP Android incubator neonatal. An early warning system was also develop for accessibility in the neonatal ward. The Android application, called Baby Control, aims to send information about the temperature of the RN via Bluetooth for users who are monitoring the babies on their shift. A quick and If there is any abrupt change in temperature, the application prompts the user to check the Neonate. Help windows are

The technology ends up being restrict by the lack of professionals in the technological area. Health informatics 2 is a branch of the course with the objective of training and encouraging students to develop software, Which facilitated the creation of the application for temperature monitoring. Neonatal incubators have a high price on the market and for this reason; it has been the inspiration for the development of a low-cost prototype that can

For future improvements, other sensors are expect to be more precise and accurate in relation to numerical values. As an NTC temperature sensor, a thermocouple (electronic component capable of reading the immediate temperature of the circuit in question) and modifications in the application according to its precise values.
