- A biosensor and data presentation solution for body sensor networksPublication . Neves, Paulo Alexandre; Caldeira, J.M.L.P.; Mendes, Américo; Pereira, Orlando; Rodrigues, JoelA Body Sensor Network can sense health parameters directly on the patient’s body, allowing 24/7 monitoring in an unobtrusive way. Several tiny sensors collect and route data to a special sink node. A new intra-vaginal biosensor was developed to study the relation between temperature variations and women health conditions, such as ovulation period, among others. We present a biosensor prototype and some initial results on real scenarios with a woman. One of the main issues in a body sensor network is the transformation of the sensor raw data into meaningful medical data for medical staff. Several approaches exist, from mobile device-based approaches to more powerful hardware such as a personal computer. This paper presents our current work in body sensor networks, namely a prototype for intra-vaginal temperature monitoring with initial results, and a mobile tool for data presentation of a three-tier body sensor network. The gathered results demonstrate the feasibility of the approach, contributing to the widespread application of body sensor networks.
- Body sensor network mobile solutions for biofeedback monitoringPublication . Pereira, Orlando; Caldeira, J.M.L.P.; Rodrigues, JoelBody sensor networks (BSN) appeared as an application of Wireless Sensor Networks (WSN) to medicine and biofeedback. Such networks feature smart sensors (biosensors) that capture bio-physiological parameters from people and can offer an easy way for data collection. BSNs also need suitable interfaces for data processing, presentation, and storage for latter retrieval. As a result, Bluetooth technology can be used to communicate with several more powerful and graphical user interface (GUI)-enabled devices such as mobile phones or regular computers. Taking into account that people currently use mobile and smart phones, it offers a good opportunity to propose a suitable mobile system for BSN networks. This paper presents a BSN mobile solution for biofeedback monitoring using the four major smart phone platforms: Symbian, Windows Mobile, Android, and iPhone. As case study, a sensing health with intelligence modularity, mobility and experimental reusability (SHIMMER) platform with a core-body temperature sensor enabled to construct the BSN was used. The four mobile applications were evaluated and validated, and are ready for use.
- A mobile core-body temperature monitoring system on androidPublication . Pereira, Orlando; Caldeira, J.M.L.P.; Lei Shu; Rodrigues, JoelRecently, Google launched the Android mobile operating system and several mobile devices already support it. This paper proposes a mobile Android-enabled tool for collecting, monitoring, and analyzing intra-vaginal temperature. A previous proposed intra-vaginal sensor acquires temperature values and sends the collected data to Android device over a Bluetooth connection. The Android tool allows women for real-time monitoring of their temperature with mobility support and following their daily life. Woman can control and detect their fertile and ovulation periods when this human parameter increases about 0.5ºC over their regular temperature. Other application of this solution includes the preterm labor prevention. The proposed system was evaluated and validated, and it is ready for use.
- Mobile solution for three-tier biofeedback data acquisition and processingPublication . Pereira, Orlando; Neves, Paulo Alexandre; Rodrigues, JoelWireless sensor networks span from military applications into everyday life. Body sensor networks greatly benefit from wireless sensor networks to answer the biofeedback challenges in healthcare applications. In such applications, data is of fundamental importance, it must be reliable and within easy reach. However, most solutions rely on a personal computer to process and display sensor data. In this paper we propose a mobile solution that draws on three-tier body sensor networks to dramatically improve data accessibility, through the use of a Java and Bluetooth-enabled mobile phone. The mobile tool features data monitoring and presentation. This approach allows data visualization by the patient or medical staff without a portable computer or specific monitoring hardware. We hope to contribute to the adoption of biofeedback for early detection of health abnormalities and lower the budget that governments spend each year in healthcare.
- A Symbian-based mobile solution for intra-body temperature monitoringPublication . Pereira, Orlando; Caldeira, J.M.L.P.; Rodrigues, JoelBiofeedback data acquisition is an extremely important task in body sensor networks (BSNs). Data collected by sensors need to be processed in order to be shown in an easy and meaningful way for the user. The use of mobile devices may support and offer new user experiences. When connected to a BSN they can aggregate and process data collected by each sensor, providing a mobile solution for a healthcare system. This mobility offers a better patients' quality of life allowing a regular daily routine and always under monitoring. This paper proposes a Symbian-based mobile solution for intra-body temperature monitoring. Mobile device connects wirelessly to an intra-vaginal temperature sensor and interacts with sensor for temperature data collection and monitoring. This system helps women to detect their fertile and ovulation periods by the increasing of their intra-vaginal temperature. The mobile system was tested and validated with success and it is available for regular use.
