Wireless sensor networks for healthcare: A survey

Electromyography (EMG) signals can be used for clinical/biomedical applications, Evolvable Hardware Chip (EHW) development, and modern human computer interaction. EMG signals acquired from muscles require advanced methods for detection, decomposition, processing, and classification. The purpose of this paper is to illustrate the various methodologies and algorithms for EMG signal analysis to provide efficient and effective ways of understanding the signal and its nature. We further point up some of the hardware implementations using EMG focusing on applications related to prosthetic hand control, grasp recognition, and human computer interaction. A comparison study is also given to show performance of various EMG signal analysis methods. This paper provides researchers a good understanding of EMG signal and its analysis procedures. This knowledge will help them develop more powerful, flexible, and efficient applications.

Techniques of EMG signal analysis: detection, processing, classification and applications

In nanopore analytics, individual molecules pass through a single nanopore giving rise to detectable temporary blockades in ionic pore current. Reflecting its simplicity, nanopore analytics has gained popularity and can be conducted with natural protein as well as man-made polymeric and inorganic pores. The spectrum of detectable analytes ranges from nucleic acids, peptides, proteins, and biomolecular complexes to organic polymers and small molecules. Apart from being an analytical tool, nanopores have developed into a general platform technology to investigate the biophysics, physicochemistry, and chemistry of individual molecules (critical review, 310 references).

Nanopore analytics: sensing of single molecules

Nanois a big prefix-word. Much of contemporary chemistry focuses on small scale structures, and indeed, molecular science is intrinsically on the nanometer scale. Selecting material for this review of “nanoelectrochemistry” involved a necessary arbitrariness of defining what “nano” means. Here, it refers to a dimensional scale of electrodes and electrochemical events, as opposed to time or volume or mass. Still, most of molecular chemistry fits within the 1-1000 nm range of dimensions, as does a substantial body of charged or conducting substances, e.g., microand nanoparticles, colloids, emulsions, and aerosols. The topology of conducting substances can have nanoscopic dimensions, with mesoporous materials such as areogels and xerogels being contemporary examples. These are important topics, as are nanoparticle applications in bioanalysis, catalysis, and electrocatalysis, and nanomaterials such as fullerenes, carbon nanotubes and networks, semiconductor nanoparticles, and arrays of nanoelectrodes and nanopores. With apologies to those topics, I have chosen to whittle the scenery down to the electrochemistry of nanoparticles, and single nanoelectrodes and nanopores. Within these, attention will be biased toward metal nanoparticles having dimensions of only a small number of nanometers, because it is in the 10 nm and lower size range where many significant recent advances have been made. Similarly, I will focus mainly on single nanoelectrodes and nanopores, as opposed to arrays thereof. The literature cited here is predominantly not over a decade old; a lot has happened, and quickly. I hope the reader will find it an interesting decade. What has promoted the rapid advances in the 1-10 nm range of dimensions? For nanoparticles, progress has been stimulated by synthetic innovations; for single nanoelectrodes and single nanopores, similarly by advances in methods of fabrication. Further, while making something that is really small can be special, it does not push science forward unless one can demonstrate its size and shape and chemical composition. So some substantial attention will be given to developments in fabrication and characterization. Knowing what you have prompts the more interesting and burning questions of how do its properties (of any kind, spectroscopic, electron transfer, etc). depend on its size, on the dimensions of other substances and structures that it interacts with (as in a nanopore), on the particular geometry of the small size, and of course on the extent that the chemist and electrochemist can tailor the composition and/or surface of the small particle/electrode/pore object to further expand its range of properties and usefulness. The authors cited in this report are leaving the first trackssto some extent tentative trackssin the scientific sand in these areas of nanoscience.

Nanoelectrochemistry: metal nanoparticles, nanoelectrodes, and nanopores.

We introduce a two-dimensional method for mass spectrometry in solution that is based on the interaction between a nanometer-scale pore and analytes. As an example, poly(ethylene glycol) molecules that enter a single α-hemolysin pore cause distinct mass-dependent conductance states with characteristic mean residence times. The conductance-based mass spectrum clearly resolves the repeat unit of ethylene glycol, and the mean residence time increases monotonically with the poly(ethylene glycol) mass. This technique could prove useful for the real-time characterization of molecules in solution.

Single-molecule mass spectrometry in solution using a solitary nanopore.

There are thousands of different nanometer-scale pores in biology, many of which act as sensors for specific chemical agents. Recent work suggests that protein and solid-state nanopores have many potential uses in a wide variety of analytical applications. In this review we survey this field of research and discuss the prospects for advances that could be made in the near future.

Single Molecule Mass Spectrometry in Solution Using a Solitary Nanopore

The Elite Care Information Technology Group has deployed a system with many elements of pervasive computing, including portable and wearable devices and wireless networking, to create intelligent and responsive work and living spaces for the elderly in a residential setting. Elite Care based the setting's layout on an apartment complex rather than a hospital with its hallways and rooms. By using a social care model that has the staff making house calls rather than doctors making rounds, the residents continue to live as normally as they can. In this scheme, pervasive sensors and staff assist residents in maintaining their independence, offering assistance as necessary and using the pervasive sensors to monitor vital signs and health indicators. Elite Care has harnessed the technology in direct and important ways to construct a more humane and human world for its residents and staff.

Using pervasive computing to deliver elder care

I examine a class of pervasive computers: radio frequency identification tags. RFID tags turn everyday objects into network nodes that uplink IDs and status data to enterprise databases, storing new information as needed. They literally vanish into commonplace objects, offering efficiencies in handling, location, and condition tracking. However, some people caution that we must implement privacy and security features from the ground up to avoid covert reuse of the tags.
