In recent years, many studies have focused on the development of wearable antennas, which enable us to obtain different parameters pertaining to different applications. Data acquired by sensors placed at different locations on or inside the body can be transmitted wirelessly to a central location some distance away Applications of this technology include military, health, and gaming. In medical applications,...
Sensors are widely in use because of low cost and multi functionality. Cognitive radio is nothing but intelligence in some form. Cognitive radio is a form of wireless communication in which a transceiver can detect the availability of channels. Wireless sensor networks are widely being deployed but some of the challenges that arise in wireless sensor network can be overcome by using cognitive radio...
As the global population ages, assisted living technologies for the elderly are becoming more popular. A person normally performs activities of daily living (ADLs) on a regular basis. A person's ability to perform recurring ADLs indicates the person's wellness. Anomalies in activity patterns of a person might indicate changes in the person's wellness. A method is proposed in this paper for detecting...
Stress in the workplace is known to be detrimental to one's physiological and psychological health. This paper proposes a wearable stress monitoring system using a body sensor network (BSN). BSNs are made up of a number of wearable/implantable biosensors that work together to perform a common task The system was accurately able to monitor the stress of an individual and display the results in an intelligible...
We introduce an action selection framework for the advanced behavioural animation of virtual creatures. In modern creative media, the behavioural animation of characters which act in a believable fashion is an ongoing challenge. Traditional action selection approaches which attempt to make an agent act rationally often fall short of the believability required for the modern consumer. Often the most...
Recent advancements in wireless technologies and the widespread availability of smartphones equipped with several physical and virtual sensors are leading to the emergence of novel mobile healthcare scenarios where patients with critical physical/behavioral conditions can be provided with anywhere and anytime care assistance even while on the move. Crowdsensing, through the massive use of smartphone...
Activity Monitoring is a key feature of health and well-being assessment that has received increased consideration from the research community over the last few decades. Body worn sensors and smart devices are widely used in Activity Monitoring in order to capture and classify large amounts of data over short periods of time, in a relatively un-obtrusive manner. Change point detection is a technique...
12 Participants wore 3 different connected heart rate sensors during sleep (i.e. electrodes, chest belt, smartwatch). They consult the respective reports and filled a questionnaire to help us to identify which one is the most acceptable device to monitor sleep. Chest belt was perceived as the easiest device to use and was considered as reliable as electrodes. Taken together and in line with the Technology...
Dementia is a clinical syndrome of cognitive deficits that involves both memory and functional impairments. While disruptions in cognition is a striking feature of dementia, it is also closely coupled with changes in functional and behavioral health of older adults. In this paper, we investigate the challenges of improving the automatic assessment of dementia, by better exploiting the emerging physiological...
In this work, we describe the state of clinical monitoring in the intensive care unit and operating room, where patients are at their most fragile and thus monitoring is most heightened. We describe how large amounts of data generated by monitoring patients' physiologic signals, along with the ubiquitous aspecific threshold alarms in use today, cause dangerous alarm fatigue for medical caregivers...
This work presents our initial approach to remote sensing and precision agriculture for monitoring crop fields in Colombia. Using an autonomous quadcopter UAV (unmanned aerial vehicle) equipped with a multispectral camera onboard, our goal is to provide farmers with an integrated tool for measuring and assessing live green vegetation by assembling a terrain image mosaic based on capturing multispectral...
In this paper we propose an in-home healthcare monitoring system offering several uses. It helps the elderly person to complete the activities independently in their own lives and at the same time facilitates family members and care provider to track inhabitants. The main idea is to have several sensors that can be used at home and enables full and tightly controlled elderly patient care. Each modality...
A growing number of elderly people in Poland and Europe forces to look for new solutions for the continuous monitoring of people health state. This approach allows elderly for an action in case of dangerous situations for older patients' life (state before heart attack or stroke, etc.). The system for continuously monitoring the health state also allows a quick action of first contact doctors in the...
Nowadays, many people, and not only the ones with health problems are being more health conscious. With the advent of sensor based technologies, it has become possible to create wearable wireless biometric sensor networks, known as Body Sensor Networks (BSNs) which allow people to collect their health data and send it remotely for further analysis and storage. Research has shown that the use of BSNs...
Traditional healthcare solutions oblige patients to stay in hospital; bio-signal monitoring and treatment dosing require the presence of specialized personnel. In turn, this scenario implies high-cost, especially for chronic diseases or fragile people surveillance. Wearable sensor-based healthcare solutions may be an effective approach for lowering costs, since they offer good performance and can...
Monitoring the health of a residual limb in prosthesis is key to detect early signs of tissue injury, and could improve patient quality of life. However, monitoring at skin level could induce possible discomfort and irritation, making the skin susceptible for breakdown. The use of non-invasive sensor technologies within the flexible liner of the prosthetic device can alleviate these issues. The rehabilitation...
In remote healthcare monitoring and care delivery, obtaining the right information at the right time is critical. For these systems, designing an efficient MAC protocol that is able to meet the challenges on network quality such as throughput, latency, data reliability and energy saving is an imperative task. This paper presents a polymorphic, multi-behavioral MAC protocol called PEAM (Polymorphic,...
Technology scaling enables today the design of ultra-low power wearable biosensors for continuous vital signal monitoring or wellness applications. Wireless Body Sensor Networks (WBSN) integrate wearable sensing nodes for an accurate measurement of the desired physiological parameter, e.g. Electrocardiogram (ECG), and a personal gateway for the collection and processing of the data. The diffusion...
Pulse oximetry is a technique used for measurement of oxygen level (oxygen saturation) of the blood. It is a simple and effortless method for measurement of how well oxygen is being transported to different organs of your body from your heart. Recent trends in the miniature and wearable device concept has fostered a substantial change in the field of biomedical engineering & its product development...
The emergence of new connected devices has opened up new opportunities and allowed to imagine concepts that bring computer sciences and social sciences closer together. In particular, today's increasingly sophisticated miniature sensors allow to track and understand human activities and behavior with a great precision. Taking different approaches and perspectives, we use in this paper smartwatches...
