2013, International Journal of Sensor Networks and Data Communications

AI-generated Abstract

The paper discusses advancements in sensor networks, specifically focusing on biosensor and L-sensor networks. Biosensors convert biological responses into electrical signals and have evolved significantly since their inception in the 1960s. L-sensor networks leverage the biosensor concept, considering the human body as a portable, low-power sensor for various environmental parameters. The research highlights the innovative potential of using human bodies and networks of individuals to collect data on metrics like temperature, pressure, and pollution, while addressing challenges such as signal extraction from bio-potentials.

An approach to the classification of unknown biological agents with cell based sensors

1998

The broad-spectrum sensitivity of cell based biosensors offers the capability for detecting previously unknown biological agents. One cellular parameter that is often measured is the action potential of electrically active cells. However, the complexity of this signal makes interpretation of the cellular response to a compound difficult to interpret. By analyzing shifts in the signal's power spectrum, it may be possible to classify the ionic channels modulated by the agent.

BIOSENSORS-Analytical Device

Journal 4 Research - J4R Journal, 2016

A biosensor is an analytical device which converts a biological response into an electrical signal. The term biosensor is often used to cover sensor devices used in order to determine the concentration of substances and other parameters of biological interest even where they do not utilize a biological system directly. Biosensors have become essential analytical tools, since they offer higher performance in terms of sensitivity and selectivity than any other currently available diagnostic tool. With appropriate progress in research, biosensors will have an important impact on environmental monitoring, reducing cost and increasing efficiency. Biosensors represent a rapidly expanding field, at the present time, with an estimated 60% annual growth rate; where major focus is on health care industry. Although there use is unquestionable in the field of agri food, research, security and defence. In this paper various aspects of biosensors have been touched.

The Commercial Application of Biosensors as an Analytical Device

International Journal of Current Microbiology and Applied Sciences, 2020

Biosensors consist of a receptor, a transducer, an amplifier and a display monitor. A bioreceptor identifies the target analytic and a transducer converts the recognition event into a measurable electrical signal. A wide range of subjects from small protein to large
