“…For example, noninvasive ambulatory monitoring of ECG on human chest can help detect multiple important features of heart malfunction like irregular heartbeat (arrhythmia) [25] . EMG reflects human muscle activity and can identify neuromuscular diseases and serve as a control signal for prosthetic devices or other machines [21] . EEG measured from the surface of human scalp can be used to not only capture cognitive and memory performance [26] , but also chart brain disorders like epilepsy [27] and stroke [28] .…”

“…The stretchable coil, however, has the blue colored PET facing up because PET has demonstrated good biocompatibility [20] but some people's skin can be allergic to Al. For the three EP electrodes, the inter-electrode distance is set to be 2 cm for effective EP signal recording [21] . The FS is designed with a 1/5 ribbon width to arc radius ratio in order to balance the trade-off between stretchability and occupied area, according to our recent mechanics of serpentine research [22] .…”

Epidermal electronics is a class of noninvasive and unobstructive skin-mounted, tattoo-like sensors and electronics capable of vital sign monitoring and establishing human-machine interface. The high cost of manpower, materials, vacuum equipment, and photolithographic facilities associated with its manufacture greatly hinders the widespread use of disposable epidermal electronics. Here we report a cost and time effective, completely dry, benchtop "cut-and-paste" method for the freeform and portable manufacture of multiparametric epidermal sensor systems (ESS) within minutes. This versatile method works for all types of thin metal and polymeric sheets and is compatible with any tattoo adhesives or medical tapes. The resulting ESS are multimaterial and multifunctional and have been demonstrated to noninvasively but accurately measure electrophysiological signals, skin temperature, skin hydration, as well as respiratory rate. In addition, planar stretchable coils exploiting double-stranded serpentine design have been successfully applied as wireless, passive epidermal strain sensors.

“…It is based upon the measurement of frequency responses via small signal perturbations, obtained using a network analyzer. Another method, which doesn't require expensive equipment is based upon the step change in transient response, the time domain data is then used for the identification of frequency responses [26].…”

Abstract:In modern distributed energy systems (DES), focus is shifting from the conventional centralized approach towards distributed architectures. However, modeling and analysis of these systems is more complex, as it involves the interface of multiple energy sources with many different type of loads through power electronics converters. The integration of power electronics converters allows distributed renewable energy sources to become part of modern electronics power distribution systems (EPDS). It will also facilitate the ongoing research towards DC-based DES which is mostly composed of commercial DC-DC converters whose internal structure and parameters are unknown. For the system level analysis, the behavioral modeling technique is the only choice. Since most power electronics converters are non-linear systems and linear models can't model their dynamics to a desired level of accuracy, hence non-linear modeling is required for accurate modeling. The non-linear modeling approach presented here aims to develop behavioral models that can predict the response of the system over the entire operating range. In this work, either a lookup table or a polytopic structure-based modeling technique is used. The technique is further applied to cascade and parallel connected converters, being two DES scenarios. First the procedure is verified via application to switching models in a simulation and then validated for commercial converters via experiments. The results show that the developed behavioral models accurately predict both the transient and steady state response.

“…The response is split as a sum of first and second order subsystems responses, and each subsystem is identified by simple equations. Nevertheless, [12] focuses on the identification of the output network of the model and the method presents some intrinsic limitations (sometimes it is difficult to split the response as a sum of subsystems responses).…”

Today, "black-box" behavioral models of power converters are becoming interesting for system-level analysis. These models can be used to evaluate the response of power electronics systems which are composed of commercial converters, since they can be fully parameterized by analyzing the actual converter response. In this paper a new identification method of "black box" models for DC-DC converters is presented. This method is based on the analysis of the step transient response of the converter, which is obtained by means of simple experiments. The identification of the model is carried out using well established fitting algorithms, which can be applied using commercial tools. I.978-1-4244-4783-1/10/$25.00 ©2010 IEEE
