Plenary Lecture:          Modeling and Optimization of Electrostatic Processes by Using Design of Experiments Methodology

Abstract: Design of experiments (DOE) is a systematic method to determine the relationship between the control variables and the output of a process. Research and development of new processes can largely benefit from the use of this methodology, as demonstrated by several examples in which it has been successfully employed for the modeling and optimization of various electrostatic technologies. The presentation will briefly describe the recent advances achieved by the Applied Electrostatics Research Unit of the PPRIME Institute of the University of Poitiers, France, in the development of electrostatic processes for: (1) separation of granular mixtures originating from waste electric and electronic equipment; (2) tribo-charging of powders in food industry; (3) corona-charging of non-woven fabrics for air filtering applications.  In each of these cases, DOE enables the evaluation of the effects of the control variables, the identification of the optimal operation conditions, and the assessment of the robustness of the process.

Plenary Lecture:          FES in movement rehabilitation after spinal cord injury, from biological brace to gating spinal network structures.

Abstract: Functional Electrical Stimulation (FES) can be a versatile tool for support of movement rehabilitation. On basis of non-invasive (electrodes at the skin surface) or invasive (implanted electrodes) techniques there are 3 options for reactivation of lost muscle functions: 1) Stimulation of efferent nerves - neuromuscular stimulation - as an early and still established method, 2) Direct activation of muscle fibers - muscle stimulation - in absence of the motor nerve, which can lead to similar contraction responses, and 3) Stimulation of afferent nerve structures, which can lead to improvement in impaired movement patterns by artificially substitution of missing neural inputs to central neuronal networks in the spinal cord - movement pattern generators.

Applications of electrical stimulation for restoration of movement reach back in the 18th century. At this time stimulators based on electrostatic discharge became available and were applied for treatment of post-stroke movement disorders. Though over the years we see a constant growth in the knowledge on physiology and pathophysiology of movement, technical equipment progress was limited till the invention of the bipolar transistor, mid 20th century, that suddenly enabled the construction of compact battery-powered stimulators. Numerous non-invasive and implantable devices for various applications where develop since, for experimental and clinical research, only few got transferred to market and permanent availability for patients in need.

Earlier concepts focused on stimulation of efferent motor nerves for direct reactivation of paralysed muscles or muscle groups; FES induced muscle contractions acted as kind of biological braces. Extension of these concepts to multiple channels and inclusion of bio-signal and sensor feedbacks led to closed-loop approaches with the intention of achieving complex "more natural" movement patterns. Many difficulties were experienced regarding handling of equipment, costs and achievable stability of control.

In the recent past new developments started to rely more in taking advantage from remaining intact neural structures in and below the lesion zone in the spinal cord. There are promising developments in using non-invasive stimulation of posterior roots at the lumbar spinal cord level to assess, in combination with multi-channel EMG and sensor recordings, functional injury profiles. These can be of value for primary post injury assessment and intervention planning as well as for monitoring of applied protocols and biological developments with time.  Similar setups can act as neuroprosthesis for enabling, augmenting or modifying movements by influencing altered central control mechanisms via non-invasively or epidurally placed electrode arrangements.

Plenary Lecture:       Plasmonic based Electrical Impedance Spectroscopy, P-EIS: theoretical and experimental aspects

Abstract: The main advantage of P-EIS versus the classical EIS analysis is given by the increased spatial resolution of P-EIS assays without using (arrays) of microelectrodes or implementing scanning electrochemical microscopy. When performing P-EIS measurements, the whole sensing area is accessible with exquisite spatial resolution, which is not limited by the size or distribution of the electrodes (as in the case of EIS) but solely by the (lateral) propagation length of the surface plasmons. Depending on sensor structure and incident light wavelength, this spatial resolution could reach low, sub-micrometer range. The applicative potential of the technique is outstanding, yet important theoretical and experimental advances have yet to be realized. The basic formalism relating SPR to the local surface charge density when applying an AC potential modulation to an electrode (also presenting plasmonic properties) and the interfacial impedance was already developed [1, 2].

We now highlight the main results [3] and detail the actual conditions allowing assessment of the amplitude and phase of the impedance (as measured by conventional EIS) from P-EIS signal.

Moreover, based on the Drude model and a transfer-matrix approach we emphasize the effect of the AC field not only on the oscillation of the SPR angle but on the entire reflectivity curve, as well.

Comparison between classical EIS and P-EIS measurement with emphasis on experimental limitations is also presented in the context of a novel plasmonic EIS microscopy system, which is currently developed at ICB.

Plenary Lecture:          Modeling and Optimization of Unobtrusive Smart Sensing and Pervasive Computing for Healthcare

Abastract: The world’s population is ageing fast. According to the United Nations the median age for all world countries will rise from 28 now to 38 by 2050. Also, is estimated that by 2050, the population over 60 years will increase worldwide from 11% to 22%, a higher percentage (33%) of elderly population will be in developed countries. In this context, governments and private investors, in addition to work for increase efficiency and quality of healthcare, are searching for sustainable solutions to prevent increase expenditure on healthcare related with higher care demands of elderly people. As such, instrumented environments, pervasive computing and deployment of a seemingly invisible infrastructure of various wired and/or wireless communication networks, intelligent, real-time interactions between different players such as health professionals, informal caregiver and assessed people, are created and developed in various research institutions and healthcare system.

This presentation reviews the recent advances in the development of sensing solutions for vital signals and daily activity monitoring.

Concerning the embedded processing, communication and interoperability requirements for smart sensing devices a critical analysis of the existent solutions and a proposed innovatory solutions are discussed. Special attention is granted to wireless sensor network, M2M and IoT as so as to ubiquitous computing particularly smartphone apps applications for healthcare. A fast prototyping vital signs and motor activity monitor as so as the usage of IEEE1451.X smart sensor standards for biomedical applications are included in the presentation.

The creation of novel smart environments including remote vital signs and motor activity monitoring devices for health monitoring and physiotherapy interventions promote preventive, personalized and participative medicine, as in-home rehabilitation that can provide more comfort to the patients, better efficiency of treatments, and lower recovery periods and healthcare costs. The use of unobtrusive smart sensing and pervasive computing for health monitoring and physiotherapy interventions allow better assessment and communication between health professionals and clients, and increase likelihood of development and adoption of best practice based on adopting recognized research-based techniques and technologies, and sharing knowledge and expertise.
