The outermost layer of the human skin, the stratum corneum (SC), is comprised of structurally inter-positioned anatomical regions. This inter-positioning renders the electrical characterization of its individual region difficult. To address this difficulty, the SC’s electrical properties at the cellular level were investigated. Impedance measurements were performed using a planar microelectrode...

The paper presents an overview of the electrical bio-impedance (EBI) signal decomposition into its cardiac and respiratory components. This problem mainly originates from the nonstationarity of the signal components and overlapping of their harmonic spectra. In the introductory part of the paper, an overview of the bio-impedance signal decomposer (BISD), as a solution of the problem, is accompa...

Noninvasive detection is a fundamental prerequisite for pervasive healthcare system and biosensing. Along with different noninvasive techniques such as ultrasound, X-ray, magnetic resonance and optical imaging, electrical impedance spectroscopy is emerging as more suitable technique for tissue level diagnosis. This paper presents a noninvasive technique for bioelectrical impedance estimation by...

This paper proposes a bio-potential measurement apparatus including a wireless device for transmitting acupuncture bio-potential information to a remote control station for health conditions analysis and monitor. The key technology of this system is to make replaceable foam-rubber cushions, double-side conducting tapes, chip and antenna on the radio frequency identification (RFID) tag. The foam...

in this study, a novel variable impedance control for a lower-limb rehabilitation robotic system using voltage control strategy is presented. the majority of existing control approaches are based on control torque strategy, which require the knowledge of robot dynamics as well as dynamic of patients. this requires the controller to overcome complex problems such as uncertainties and nonlinearit...

There is significant interest in the use of electrodes for sensing or actuation in bio-fluidic microsystems. Within these systems high levels of reliability are crucial and complimented by requirements for extremely low levels of false positive and false negatives. This paper extends previous work on impedance and oscillation based condition monitoring of electrode arrays by investigating the a...

A biosensing platform based on the principle of real-time unlabeled impedimetric detection has been developed. The platform detects bio-targets by measuring impedance changes in real-time. This biosensor is aimed at multiple segments of the life sciences market and is planned for commercialization in the near future. These products will leverage monolithic integration concepts, unique device te...
