Accelerometer sensors are ubiquitously available in consumer electronics such as smart phones and wearables. So far, mainly biomedical applications using accelerometers focus on providing contextual information like step counting, activity monitoring or motion artifact detection and suppression. Still, these sensors offer interesting opportunities for vital sign monitoring, even potentially for the demanding case around cardiac arrest. In this paper we show a basic feasibility study to compare the performance of an accelerometer (ACC) based pulse detection approach versus a commercially available device. For healthy subjects we found an excellent sensitivity of ACC-based pulse detection. The ACC performance was not influenced by changes in position, and ACC sensor placement was easy. The decision time for the commercial pulse detection device ranged from 10.0 – 25 s, while for our ACC-based approach it was 3.5 – 5.0 s using a trained classifier. From this preliminary study we conclude that ACC sensors might offer interesting opportunities for applications in emergency care for vital sign detection.

Car racing on track is a physically and mentally demanding sport. The car is monitored with high accuracy to improve performance, but nothing is measured on the driver. To achieve high performance, it is important that the driver is at their peak both physically and mentally. Knowing the mental state of the driver and keeping them in their individual focus zone can help improve the performance of the team. The stress level of four drivers is monitored during a 10hr race. Individual Stress Zones are calculated and used to distinguish mental states of distraction, focus and distress. The results show that performance is 1.7% better when focused than when distracted (for 1 of 4 drivers) and 2.3% better than distressed (for 3 of 4 drivers).

For the first time, a wearable personal distributed exposimeter (WPDE) is designed and calibrated for the Long-Term Evolution (LTE) 800 and 2600 MHz downlink bands. The proposed WPDE has a 68% confidence interval of 4.8–5.6 dB for different number of antennas and polarizations. Measurements of the WPDE are compared and validated with a commercial exposimeter in a real environment.

In order to improve healthcare services and support clinical professionals, it is important to develop the unobstructive and automatic ADLs monitoring system for healthcare applications. Currently, various works have been developed for the monitoring of daily activities, such as ambulation, kitchen task, food and fluid intake, dressing, and medication intake while only few works paid attention to the housekeeping task. Housekeeping activity is a complex task, generally important for the several clinical assessment tools. In this work, we design and develop a wearable sensor-based activity recognition system recognize housekeeping tasks and classify the activity level. The proposed system achieves 90.67% accuracy for housekeeping tasks recognition, and 94.35% accuracy for activity level classification, respectively. The results of the experiment demonstrate that the system is reliable and fulfills the requirements of the unobstructive, objective, and long-term monitoring system.

Cardiovascular vital signs are measured using continuous wave (CW) radar at 2.45GHz with a body-contact antenna. Using a previously collected database of thirty second recordings at paced breathing conditions, CW radar signals were measured together with heart sounds, electrocardiogram (ECG), respiration and impedance cardiogram (ICG) were as reference signals. Using arbitrarily chosen features from the radar signal, the systolic time intervals (STI)s from radar are compared with those from the ICG. The correlation coefficients between the STIs of radar and ICG were 0.72, 0.66 and 0.81 for the pre-ejection period, left ventricular ejection time and electromechanical systole respectively. The p-value was below 0.0001 for all coefficients, indicating a significant correlation. The results indicate that the radar signals capture cardiomechanical signals, which have great potential to be used for STI estimation in ambulatory conditions.

In this work, we present an in-ear system for physiological and psychological stress detection based on photoplethysmography, acceleration, and temperature measurements. The complete system is used to extract vital signs from healthy subjects, who are exposed to psychologically demanding tasks. The newly developed sensor system is integrated into our IPANEMA body sensor network and, thus, can be used in combination with several sensor modalities. The capability of the stress level estimation is validated in an human stress experiment. To obtain information on the current stress level, several well-known indicators are utilized like the heart rate variability, surgical stress index or the Oliva and Roztocil index.

This work proposes an Android-based platform to warn the medical staff of the onset of allergy reactions during a provocation test in a hospital. The portable system carries out the analysis of the heart rate variability for the early detection of allergic reactions in patients undergoing allergy provocation tests at hospitals. The proposal is composed of an ECG (electrocardiogram) acquisition system and an Android device (Smartphone, Tablet) that monitors and evaluates the results in real time, increasing the safety of allergic tests. At present, food and drug allergic tests are a major problem for patients because of their long duration and intrusion. However, the authors have designed an algorithm for detecting allergy reactions that have focused on reducing the time of the tests and the number of doses. This algorithm runs on an Android platform, and it is able to provide alarms for the medical staff if there is an allergy reaction. The proposed monitoring system is very suitable for the health monitoring during the provocation tests.

Body temperature is among most important biometric indicators that are normally checked in both domestic and hospital environments. The way to collect such parameter could be dramatically improved thanks to the Epidermal Electronics technology enabling plaster-like devices suitable to on-skin temperature sensing and capable of wireless communication with an electromagnetic reading module. The practical applicability of an eco-friendly battery-less epidermal thermometer, compatible with the UHF RFID standard, is here discussed by the help of experimentation with some volunteers. Comfortable reading procedures can be applied for both the operator and the patient. Experiments revealed a non negligible sensitivity of the temperature measurement versus the mutual distance between the reader and the sensor, that must be removed by a proper threshold filtering. Finally, the analysis of the sensor response for different placement position over the body, demonstrates that the axilla and chest loci provide only 0.6°C deviation from a reference tympanic measurement and are well accepted by the user which does not complain about the presence of the sensor.

The purpose of this study was to explore the characteristic of trunk angle and flexibility of spine in lumbar disc herniation (LDH) patients, non-specific low back pain (LBP) patients and healthy subjects during bending exercises. 35 patients with LDH, 32 patients with non-specific LBP and 24 healthy controls participated in this experiment, volunteered to stand, then bend forward as far as possible, stay fully flexed, and return to stand with performing five cycles. As an indirect measure of spine performance, the trunk angle captured using motion sensors. We estimated the degree of spine activity by comparing the trunk angle between LDH, LBP and healthy controls in roll, pitch and yaw planes, respectively. As results, the significant differences between LDH, LBP and healthy controls in the female group of volunteers was found for trunk angle of three planes (p< 0.05). Between female and male had differences of trunk angle in LDH, LBP and healthy controls, respectively. Combined the most frequently used visual analog scale (VAS) for the pain of clinical research to explore the characteristic of subjective response of the patient on trunk angle by objective measurement, which might be a useful tool to reflect the abnormal degree of the spine in the diagnosis of spine and rehabilitation. In summary, these results advised LDH and LBP patients to do strength training reasonably to restore lumbar muscle function and assist in stabilizing the spine.
