Medical and healthcare research has been striving to find relationships between core body temperature at female genitals and certain health conditions, such as ovulation period. This paper presents a solution for intra-body temperature monitoring based on a new intra-body sensor, communication and desktop application tool. This new biosensor provides data collection that may be used to study the relation between temperature variations and women health conditions, such as, ovulation period (for both natural contraception and in vitro fertilization purposes) among others. The motivation for this work focuses on the creation of this e-Health solution that will fill the gap we realize in medical technology. The proposal was tested and validated by a medical team and it was concluded that this new biosensor performs perfectly

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
A sudden death prevention system for babies
The growth of the smartphones market share has driven the entry of a large number of new opportunities to launch new applications/mobile tools both by companies but also by individualsâ entities. The prototype solution presented here fits in the increasing emerging of smartphones applications for the health sector.
This dissertation presents a solution to prevent a sudden infant death syndrome. It includes biofeedback monitoring of babies, using body sensors to collect data that will be presented in two different mobile applications: the Main Application and the Client Application. Breathing, temperature, position, and heart rate are used, and placed to the babyâs body.
The Main Application will receive the data collected by the sensors via Bluetooth. This contains a monitoring tool, which parses and transforms raw data to be readable and understandable for users. This application will send the data to a Web service to be stored in a database that supports the entire created solution. The Client Application will consume the data stored in the database every previous second.
Both applications have an important functionality that allows the trigger of alert notifications when an error occurs with the data collected by the sensors and the caregiver is informed with an alert in a short time. This document describes in detail the whole process done to deploy a prototype that demonstrates and validates the proposed solution and is ready for use
A new wireless biosensor for intra-vaginal temperature monitoring
Wireless Body Sensors for medical purposes offer valuable contributions to improve patientsâ healthcare, including diagnosis and/or therapeutics monitoring. Body temperature is a crucial parameter in healthcare diagnosis. In gynecology and obstetrics it is measured at the skinâs surface, which is very influenced by the environment. This paper proposes a new intra-body sensor for long-term intra-vaginal temperature collection. The embedded IEEE 802.15.4 communication module allows the integration of this sensor in a Wireless Sensor Network (WSN) for remote data access and monitoring. We present the sensor architecture, the construction of the corresponding testbed, and its performance evaluation. This sensor may be used in different medical applications, including preterm labor prevention and fertility and ovulation period detection. The features of the constructed testbed were validated in laboratory tests verifying its accuracy and performance

Performance assessment of mobility solutions for IPv6-based healthcare wireless sensor networks
This thesis focuses on the study of mobile wireless sensor networks applied to healthcare
scenarios. The promotion of better quality-of-life for hospitalized patients is addressed in this
research work with a solution that can help these patients to keep their mobility (if possible).
The solution proposed allows remote monitoring and control of patientsâ health in real-time
and without interruptions. Small sensor nodes able to collect and send wirelessly the health
parameters allow for the control of the patients' health condition. A network infrastructure,
composed by several access points, allows the connection of the sensor nodes (carried by the
patients) to remote healthcare providers. To ensure continuous access to sensor nodes special
attention should be dedicated to manage the transition of these sensor nodes between
different access pointsâ coverage areas. The process of changing an access point attachment
of a sensor node is called handover. In that context, this thesis proposes a new handover
mechanism that can ensure continuous connection to mobile sensor nodes in a healthcare
wireless sensor network. Due to the limitations of sensor nodesâ resources, namely available
energy (these sensor nodes are typically powered by small batteries), the proposed
mechanism pays a special attention in the optimization of energy consumption. To achieve
this optimization, part of this work is dedicated to the construction of a small sensor node.
The handover mechanism proposed in this work is called Hand4MAC (handover mechanism for
MAC layer). This mechanism is compared with other mechanisms commonly used in handover
management. The Hand4MAC mechanism is deployed and validated through by simulation and
in a real testbed. The scenarios used for the validation reproduces a hospital ward. The
performance evaluation is focused in the percentage of time that senor nodes are accessible
to the network while traveling across several access pointsâ coverage areas and the energy
expenditures in handover processes. The experiments performed take into account various
parameters that are the following: number of sent messages, number of received messages,
multicast message usage, energy consumption, number of sensor nodes present in the
scenario, velocity of sensor nodes, and time-to-live value. In both simulation and real
testbed, the Hand4MAC mechanism is shown to perform better than all the other handover
mechanisms tested. In this comparison it was only considered the most promising handover
mechanisms proposed in the literature.Fundação para a CiĂȘncia e a Tecnologia (FCT
A biosensor and data presentation solution for body sensor networks
A Body Sensor Network can sense health parameters directly on the patientâs 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
Mobile platform-independent solutions for body sensor network interface
Body Sensor Networks (BSN) appeared as an application of Wireless Sensor Network
(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. A new BSN platform called Sensing Health with Intelligence
Modularity, Mobility and Experimental Reusability (SHIMMER) presents an excellent
opportunity to put the concept into practice, with suitable size and weight, while also
supporting wireless communication via Bluetooth and IEEE 802.15.4 standards.
BSNs also need suitable interfaces for data processing, presentation, and storage
for latter retrieval, as a result one can use Bluetooth technology 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 SHIMMER-based networks.
This dissertation proposes a mobile system solution with different versions created
to the four major smart phone platforms: Symbian, Windows Mobile, iPhone, and
Android. Taking into account that, currently, iPhone does not support Java, and Java
cannot match a native solution in terms of performance in other platforms such as
Android or Symbian, a native approach with similar functionality must be followed.
Then, four mobile applications were created, evaluated and validated, and they are
ready for use
iBalance-ABF: a Smartphone-Based Audio-Biofeedback Balance System
International audienceThis article proposes an implementation of a Kalman Filter, using inertial sensors of a Smartphone, to estimate 3D angulation of the trunk. The developped system monitors the trunk angular evolution during bipedal stance and helps the user to improve balance through a configurable and integrated auditory-biofeedback loop. A proof-of-concept study was performed to assess the effectiveness of this so-called iBalance-ABF - smartphone-based audio-biofeedback system - in improving balance during bipedal standing. Results showed that young healthy individuals were able to efficiently use ABF on sagittal trunk tilt to improve their balance in the ML direction. These findings suggest that iBalance-ABF system as a Telerehabilitation system which could represent a suitable solution for Ambient Assisted Living technologies
