This letter introduces a novel in vivo method for determining the dielectric properties of deep human tissues, including lungs. A surgery-free method is proposed for an on-body monitoring system to evaluate the electrical properties of internal body organs and to detect irregularities in real time. The method uses a set of electrodes (16 or 40 MHz in operational frequency) to obtain data that relates the electrical properties of the underlying biological tissue(s) to the measured port scattering parameters. By using multiple electrodes, effects from outer layers (skin, fat, and muscle) can be suppressed, allowing for an accurate characterization of deeper layers. Specifically, the dielectric constant is expressed as a weighted sum of the scattering parameters from each probe. The weights of the scattering coefficients are then determined through a training process to ensure that various changes in the outer layers do not contaminate the extraction of the dielectric constant(s) associated with deeper tissues.Index Terms-Biomedical sensor, human health monitoring, signal-to-noise ratio (SNR), tissue dielectric properties, wearable electronics.

The technology advances in rapid pace and it contributes in the steps to facilitate the easiness of life. The real time services are emerged substantially in the world of modernization. The most important revolution of real time technology is in the field of health care scenario. It is very important to monitor various medical parameters and post operational days. Hence the latest trend in Healthcare communication method using Internet of things (IoT) is adapted. The main objective of our 'IoT based Medical home' is to continuously monitor the health status of a patient over the internet. This proposed system of health care management is specially supposed to design as a Medical Home for older patients and this is equipped such that it can be a complete protection for the older patients even when they are in lone situations. For this Real time health status updation , Real time ECG, BP, Glucose level, temperature monitoring, Automatic wheel chair access facility , Medicine reminder, Panic switch facility, Automatic ambulance calling facility are provided. This medical home is a fabulous model which has to be brought in to prevalence for the future. General Terms IoT. Cloud computing Keywords Real time health monitoring, Health care sensor networks.

A wearable wrap-around sensor is proposed for continuous measurement of the permittivity of biological tissues deep into the torso (specifically, lung, and heart). The sensor is composed of multiple electrodes (antennas), excited at a single low frequency. A postprocessing technique is applied to the scattering data received by the electrodes to extract the permittivity of the tissues. The extraction process, which suppresses interferences from skin, fat, muscle, and bone layers is important especially with the fact that electrical properties may deviate from one person to another. In addition, the physical layout of the sensor provides the means to excite specific segments in a manner that localizes the extracted dielectric constant. This capability can allow for rudimentary localized imaging of the torso's cross section and different regions of the body using a low-cost portable sensor.Index Terms-Biomedical sensor, tissue dielectric properties, human health monitoring, wearable electronics. 1530-437X
