We designed and manufactured a working prototype of a wearable respiratory belt. The belt can work as a stand along system or can be embedded into clothes. The system is intended for remote health monitoring (particularly to monitor human respiration) such as home healthcare, remote medicine and remote socio-medical assistance as well as to monitor patients. The fully functional prototype proofs the concept that the elongation in the respiratory belt causes by human respiration is accurate enough to measure and to monitor human respiration. [less ▲]

The AMM is a development tool for integration of various off-self-sensors in one miniaturized device (1cm³). It can be used for wide variety applications such: industrial, buildings, healthcare and others. In normal environmental conditions, the autonomy is achieved by photovoltaic cell and the sensors are used for monitoring temperature, humidity and light intensity. At harsh environment such as a liquid zinc bath (800°C), the specially developed package allows the system to monitor inputs. [less ▲]

The paper aims to demonstrate the benefits for a global approach that allows to define new research directions, new potential industrial markets, and increasing interest from potential users. Combining performance, economic and environmental criteria in a joint assessment approach for the target applications of sensor systems, facilitates significantly the communication between service provider and user. The environmental assessment approach for sensor systems will be available as a beta-version online tool tentatively from July 2013 onwards. Interested SMEs are invited to get involved as the LCA to go consortium will provide also a comprehensive mentoring for SMEs [less ▲]

We evaluated AJP (Aerosol Jet Printing) deposited silver layer on variety of organic substrates for the most common interconnect techniques for electronic packaging. Specifically, we checked if the AJP silver layer can be electrically interconnected by Au and Al wires bonding technique. We also evaluated suitability of AJP silver layer for surface-mount technology (SMT). We performed electrical characterization of the AJP silver layer. [less ▲]

We have proposed and explored a novel sequence in MEMS fabrication process flow. The novel MEMS fabrication process flow can be shortly described as a “packaging first, MEMS release second”. We propose to package the MEMS device first (die mount, wire bonding and encapsulation) and to perform the MEMS release as the last step in the fabrication process flow. The standard route for IC manufacturing is, that the die packaging is the last step [1]. Such approach can’t be directly transferred and used for MEMS fabrication [2]. The main reason for that, that the MEMS device after the release becomes vulnerable to any physical and chemical exposure. Such exposure can occur during transportation, handling or any post-processing (incl. the packaging). [less ▲]

In this paper, we describe a circuit-element model for the electric detection of biomolecules in translocation through a nanopore in a semiconductor-oxide-semiconductor (SOS) membrane. The biomolecules are simulated as a superposition of individual charges moving through the nanopore and inducing a charge variation on the membrane electrodes that is modeled as a current source. The SOS membrane is discretized into interconnected elementary circuit elements. The model is tested on the translocation of 11 base single-stranded C3AC7 DNA molecule, for which the electric signal shows good qualitative agreement with the multiscale device approach of Gracheva et al., while quantifying the low-pass filtering in the membrane. Overall, the model confirms the possibility of identifying the sequence of the DNA bases electrically. [less ▲]

The seriousness of the obstructive sleep apnea/hypopnea syndrome is measured by the apnea-hypopnea index (AHI), the number of sleep apneas and hypopneas over the total sleep time (TST). Cardiorespiratory signals are used to detect respiratory events while the TST is usually assessed by the analysis of electroencephalogram traces in polysomnography (PSG) or wrist actigraphy trace in portable monitoring. This paper presents a sleep/wake automatic detector that relies on a wavelet-based complexity measure of the midsagittal jaw movement signal and multilayer perceptrons. In all, 63 recordings were used to train and test the method, while 38 recordings constituted an independent evaluation set for which the sensitivity, the specificity, and the global agreement of sleep recognition, respectively, reached 85.1%, 76.4%, and 82.9%, compared with the PSG data. The AHI computed automatically and only from the jaw movement analysis was significantly improved (p < 0.0001 ) when considering this sleep/wake detector. Moreover, a sensitivity of 88.6% and a specificity of 83.6% were found for the diagnosis of the sleep apnea syndrome according to a threshold of 15. Thus, the jaw movement signal is reasonably accurate in separating sleep from wake, and, in addition to its ability to score respiratory events, is a valuable signal for portable monitoring.

Given the importance of the detection and classification of sleep apneas and hypopneas (SAHs) in the diagnosis and the characterization of the SAH syndrome, there is a need for a reliable noninvasive technique measuring respiratory effort. This paper proposes a new method for the scoring of SAHs based on the recording of the midsagittal jaw motion (MJM, mouth opening) and on a dedicated automatic analysis of this signal. Continuous wavelet transform is used to quantize respiratory effort from the jaw motion, to detect salient mandibular movements related to SAHs and to delineate events which are likely to contain the respiratory events. The classification of the delimited events is performed using multilayer perceptrons which were trained and tested on sleep data from 34 recordings. Compared with SAHs scored manually by an expert, the sensitivity and specificity of the detection were 86.1% and 87.4%, respectively. Moreover, the overall classification agreement in the recognition of obstructive, central, and mixed respiratory events between the manual and automatic scorings was 73.1%. The MJM signal is hence a reliable marker of respiratory effort and allows an accurate detection and classification of SAHs. [less ▲]

This paper proposes a novel method for the scoring of sleep apneas and hypopneas (SAHs) based on the recording and the analysis of the midsagittal jaw movements. Continuous wavelet transform was used to delineate events which were likely to contain the SAHs, while hidden markov models (HMMs) classified events. Considering 28 recordings from which awakenings were discarded, the method detected SAHs with a sensitivity and a specificity of 82.2% and 78.3% respectively. Obstructive, central and mixed respiratory events were distinguished fairly accurately. The jaw motion is hence a reliable marker of respiratory efforts and may suffice by itself to score SAHs.

Les mouvements de la mandibule donnent une image des efforts respiratoires, particulièrement en période d’apnées et d’hypopnées du sommeil. Ils sont donc une alternative à la pression oesophagienne. Cette étude a mis en évidence le potentiel d’une analyse automatique des mouvements de la mâchoire pour le diagnostique du syndrome d’apnées et hypopnées obstructives du sommeil (SAHOS) par la mesure de l’indice d’apnées et d’hypopnées (IAH).

Our study showed the potential of a surrogate of the oesophageal pressure, the jaw motion, and a dedicated automatic analysis to diagnose the obstructive sleep apnoea and hypopnoea syndrome (OSAHS). Twentyfour patients were recorded in hospital settings and the jaw motion of fifteen of them was also recorded at home with an ambulatory device. The apnoea and hypopnoea index (AHI) of the gold standard, AHI_PSG, and the two AHI from the automatic analysis of the jaw motion, AHI_H (hospital) and AHI_A (ambulatory), were compared : AHI_PSG Vs AHI_H showed good correlation (r = 0.97) and under-estimation (slope p = 0.76). AHI_A Vs AHI_H revealed good reliability with r = 0.98 and slope p = 0.99. Finally, AHI_PSG Vs AHI_A showed very good accuracy of the diagnosis with sensitivity of 90% and specificity of 100%.

In this paper, we propose a method for sleep apnea and hypopnea detection by analyzing the mandibular movements recorded during sleep. This signal, highly correlated with the esophageal pressure during apnea or hypopnea, is a good marker of respiratory efforts. The respiratory efforts and their background activity are used to detect salient mandibular movements related to sleep apnea and hypopnea, to delineate and to recognize episodes of sleep apnea and hypopnea. The method presented may be extended to others breathing disorders such as Respiratory Efforts Related Arousals (RERA). [less ▲]
