This paper presents research about design a textile-based stretch sensor for making a reliable sensing system for dance movement sensing. We examined sixteen textile-based conductive stretch sensors that were made with commercially produced conductive materials. Through the analysis of their sensitivity, linearity, hysteresis, responsiveness, and fatigue, a silver-plated conductive fabric, Technik-tex P130B, shows the best performance for dance movement sensing. Then, we tested the bonding technique, and washability of Technik-tex P130B-made sensors. The finding shows that bonding makes a noticeable impact on sensor performance. Both bonding and washing increase the sensor’s resistance. Technik-tex P130B on one side bonding has the best performance for dance movement sensing. This reliable and washable textile-based stretch sensor is utilised for dance bodysuit making for further development.

AbstractBalinese dance is the intangible cultural heritage which has become one of the main tourism draws in Indonesia, and worldwide that offers various cultural wealth with its unique qualities. It has strong characteristics, shown through the movements, music, and costumes. The richness of Balinese dance has attracted people, both scholars and tourists, to learn it. Unfortunately, it also presents a challenge for people who have just begun to learn it, due to their unfamiliarity with its terms taken from the local Balinese language. An Android-based application aimed at remedying this problem has been developed and has been evaluated for its main features and functionality. Several suggestions from initial users have been obtained and utilized for further development of the dictionary. By maintaining the multimedia features, the dictionary has become not only a reference for terms but also a practical reference for the dance movement itself. The results of the user survey suggested that further development using advanced technology could deliver more appealing experiences in learning Balinese dance. Furthermore, most of the respondents stated that the current development is appropriate as an early step in the efforts to preserve the record of Balinese dance.

The LifeChair is a smart cushion that provides vibrotactile feedback by actively sensing and classifying sitting postures to encourage upright posture and reduce slouching. The key component of the LifeChair is our novel conductive fabric pressure sensing array. Fabric sensors have been explored in the past, but a full sensing solution for embedded real world use has not been proposed. We have designed our system with commercial use in mind, and as a result, it has a high focus on manufacturability, cost-effectiveness and adaptiveness. We demonstrate the performance of our fabric sensing system by installing it into the LifeChair and comparing its posture detection accuracy with our previous study that implemented a conventional flexible printed PCB-sensing system. In this study, it is shown that the LifeChair can detect all 11 postures across 20 participants with an improved average accuracy of 98.1%, and it demonstrates significantly lower variance when interfacing with different users. We also conduct a performance study with 10 participants to evaluate the effectiveness of the LifeChair device in improving upright posture and reducing slouching. Our performance study demonstrates that the LifeChair is effective in encouraging users to sit upright with an increase of 68.1% in time spent seated upright when vibrotactile feedback is activated.

ABSTRACT A multisensor system was integrated into the P.166-DL3 Piaggio aircraft that was selected for maritime surveillance by the Italian Merchant Marine Ministry for the Coast Guard. Four aircraft equipped with such a system are now operational in Italy. Sensors include bispectral scanner, FLIR system, aerial camera system, surveillance system operator console, and related facilities. In addition, four more aircraft have been purchased, and will be in operational use in the very near future with an improved sensor system. Current Coast Guard plans are to have 12 aircraft operational for maritime surveillance; further development will include in-flight data transmission and ground data processing capabilities.

Sensors for respiratory monitoring can be classified into wearable and non-wearable systems. Wearable sensors can be worn in several positions, the chest being one of the most effective. In this paper, we have studied the performance of a new piezoresistive breathing sensing system to be worn on the chest with a belt. One of the main problems of belt-attached sensing systems is that they present trends in measurements due to subject movements or differences in subject constitution. These trends affect sensor performance. To mitigate them, it is possible to post-process the data to remove trends in measurements, but relevant data from the respiration signal may be lost. In this study, two different detrending methods are applied to respiration signals. After conducting an experimental study with 21 subjects who breathed in different positions with a chest piezoresistive sensor attached to a belt, detrending method 2 proved to be better at improving the quality of respiration signals.

Smart bearings incorporating self-powered sensors and wireless data communications with intelligence in monitoring bearing conditions can help to detect early faults in aero-engine bearings. This paper presents the challenges in design and development of a sensing system with compact and low-power consumption sensors and the procedures for sensor performance evaluation under the requirements of aerospace standard. Industrial standard DO160 testing is necessary for preliminary testing of the smart sensing system prior to being installed in aero-engine, thus a laboratory test procedure has been developed for sensor performance evaluation for the smart aero-engine bearings in this project. As a case study, this paper presents the details and results of the accelerometer evaluation following the requirements in DO160.

The development of a remote sensing system is proposed in the present study for monitoring of the electrical resistance of concrete in real time. The sensor is embedded in the concrete bulk, and the data are sent via a gateway to a computer for the data analysis. The sensibility of the sensors to the effect of the presence of a crystalline admixture has been also assessed in the study. Different cycles of drying and water penetration have been considered to assess the sensor performance in different water content conditions. Sensors have shown to capable of detecting changes in electrical resistance when humidity changes. The sensitive of the sensors to the action of waterproofing admixtures in the mortar has been also confirmed. The contribution of the temperature plays a critical role on the sensor response, and its simultaneous monitoring is recommended.

The objective of this research was to assess the performance of an embedded sensing system designed to measure the distance between a prosthetic socket wall and residual limb. Low-profile inductive sensors were laminated into prosthetic sockets and flexible ferromagnetic targets were created from elastomeric liners with embedded iron particles for four participants with transtibial amputation. Using insights from sensor performance testing, a novel calibration procedure was developed to quickly and accurately calibrate the multiple embedded sensors. The sensing system was evaluated through laboratory tests in which participants wore sock combinations with three distinct thicknesses and conducted a series of activities including standing, walking, and sitting. When a thicker sock was worn, the limb typically moved further away from the socket and peak-to-peak displacements decreased. However, sensors did not measure equivalent distances or displacements for a given sock combination, which provided information regarding the fit of the socket and how a sock change intervention influenced socket fit. Monitoring of limb–socket displacements may serve as a valuable tool for researchers and clinicians to quantitatively assess socket fit.

Shaping of the difficult-to-machine non-conductive materials such as glass, quartz and ceramic is much difficult and uneconomical by existing machining processes. As a result, wide applicabilities of these materials are still limited. Even though these materials are highly required in the field of the modern industries. To overcome the problem, a new machining method has been proposed by researchers by combining the features of electro-chemical machining and electro-discharge machining. Such combined machining process is called as electro-chemical spark machining process. Such developed machining method becomes an appropriate process for machining of non-conductive materials with significant improvement in productivity as compared to the electro-discharge machining and electro-chemical machining processes. In this article, the role of electro-chemical spark machining for machining of the non-conductive materials has been summarized and focused on the future research possibilities in the same area. This article also focuses on mechanism, process and performance parameters, variants and new developments related to the electro-chemical spark machining. As a result, this review article becomes beneficial for researchers to understand the phenomena of the electro-chemical spark machining process as well as further development in the same area.
