Biosensors: Their Fundamentals, Designs, Types and Most Recent Impactful Applications: A Review

The word “sensor” find its origin from the Latin word “sentire” which basically means ‘to identify’ anything. By hearing this word sensor, the foremost thing that springs into our minds is the concept of basic five human senses: ophthalmoception, audioception, gustaoception, olfacception and tactioception.

The working mechanism of these senses is generalized as a) reception of input signal by the sensory cells because of external stimuli b) conduction of data towards the brain for interpretation as neurological impulses c) receptors respond to the stimulus as per instructed by the interoperating center. With this brief explanation of sense, more methodical and technical definition for sensor could be established which is as follows; it is a device that obtains and responds to stimulus and signals originated from the environment.(Read more)
