Recently I postulated a new concept in the field of sensors; Lsensors. With the L-sensor I mean a living sensor. As a good and practical proposal for L-sensor I can name a neuron.

Neuron In simple terms, is a cell specialized to generate and conduct electrical impulses and to carry information from one part of the body to another. Thanks to their numerous branch-like processes, neurons interconnect forming a massive network of "wires" that extend throughout the body. By sending messages across this network, the different parts of the human body interact and communicate with each other. Every time we move, think, remember something or feel, our neurons are at work.

In our body, sensory neurons carry signals from the outer parts into the central nervous system or CNS, the speed of c in neurons is said to be about 7000 m/sec.

It is estimated that human brain contains about 1011 neurons that are interconnected via a complex network. This huge number of elements and complex interconnections among them forms the most robust, fastest and lightest weight known control system.

Considering lightweight, fast and robust action of such nervous system, why don't we use it in an aircraft or spacecraft? (Figures 1 and 2).

Efforts are currently underway to work with different conceptual types of distributed embedded sensor architectures to develop biologically inspired sensory system for aerospace vehicles. Some authors have reported works investigating the ability of living neurons to act as a set of neuronal weights, which were used to control the flight of a simulated aircraft. These weights were manipulated via high frequency stimulation inputs to produce a system in which a living neuronal network would "learn" to control an aircraft for straight and level flight.

At NASA, researches are currently in progress to work with different conceptual types of distributed embedded sensor architectures to develop a biologically inspired sensory system for aerospace vehicles.

In other studies, signal processing algorithms and bio-like distributed sensor network systems are used on large structures and integrated aerospace vehicles for acoustic emission wave source localization and preliminary results are presented. These systems allow for a great reduction in the amount of data that needs to be processed and also reduce the chances of false alarms from ambient noises.

Concerning above efforts and in connection with light weight, robustness and fast speed of real neural networks we may satisfy our selves that future aerospace vehicles will apply live distributed embedded sensor arrays mimicking human neural system.
