This paper presents design principles of a low-power and portable bioelectrical impedance analyzer. Based on the low-power and portable notion, It uses a low-power computer as the core, adopting MSP430F149 chip as the processor and utilizing AD5933 which is launched by Analog Devices and is highly integrated to measure and collect the multi-frequency impedance information. And then these data will...
We are going to propose a novel total body composition measurement device which is based on Bioelectrical-Impedance Analysis (BIA) which is temperature compensated with the aid of a computer. We are making use of aluminium electrodes for this purpose. Proximal electrodes are used to measure the voltage distant electrodes of right head and foot with an excitation current of 0.8mA at 50 KHz are used...
This paper analyses the use of Electrical Impedance Spectroscopy (EIS) to efficiently monitor cryoprotectant concentrations in cryopreservation protocols. The proposed technique can improve methods such as Liquidus Tracking (LT), allowing vitrification without exposing tissues to damaging concentrations of cryoprotectant at relatively high temperatures, and avoiding rapid temperature changes. This...
This paper presents the development of a Body Sensor Network, called the meditBSN, for health monitoring applications. It is designed around a MSP430F1611 microcontroller and a CC1101 433 MHz ISM band transceiver IC. A Bioimpedance Spectroscopy measurement condition monitoring application has been developed using the meditBSN. It incorporates three 3-D accelerometers and a skin temperature probe....
In this study, a new way of investigating a surface acoustic wave (SAW) based sensor device is reported. For that, SAW sensors with a fundamental mode of about 85 MHz and a metallization of gold were developed. Realized as one port resonators, these sensors allow the continuous detection of electric and viscoelastic properties of the same living cell culture in one measurement step. For obtaining...
Single frequency bioelectrical impedance analysis (BIA) is an inexpensive, quick and painless means of estimating body composition. In this paper, BIA parameters employed for predicting hemoglobin (Hb) in dengue patients. The BIA technique passes a low-amplitude electrical current, in the range of 500 muA to 800 muA, at a single frequency of 50 kHz. BIA data was sampled from 210 (comprises of 119...
