Telemetry and Innovative Data Analysis Systems
The trend toward the miniaturization of sensor systems will have a significant effect on how the environment is studied and monitored. “Systems on a chip” technology, for example, may replace chemistry and biology laboratories with portable hand-size instruments used for rapid chemical or biological agent detection and quantification in a myriad of situations.
It is anticipated that innovative and improved biochemical sensors would be useful in a variety of situations including, but not limited to: clinical monitoring, forensics and human or animal research. Specific sensor characteristics would complement their intended use. This applies to characteristics such as: sampling frequency, degree of accuracy, data storage capacity and data transmission frequency.
Depending on their intended purpose and use, biochemical sensors may be augmented with additional information such as other physiological measurements or geospatial determinations. Emergency response planners require current and accurate geospatial information that is readily available in interoperable databases. Advances in telemetry technology contribute greatly to the success of moving masses of data from raw sensor readings to useful database applications.
Devices need to be compatible with human comfort, and devices to be worn for weeks or months may present particular challenges. Since biochemical readings are likely to be baseline most of the times, sensing devices generally require ways to monitor contact and readiness to record. More over, where necessary, measurement fidelity should be robust to subject’s activities. The mode of data storage will need to conform to power limitations and strategies for data transmission which will require telemetry applications mentioned earlier.
In addition to biochemical monitoring and data transmission the opportunity to develop appropriate data analysis systems looms even bigger in future design considerations. Examples include: estimating blood biochemical concentrations, reconstructing patterns of biochemical consumption, and monitoring large numbers of devices to identify significant, but infrequent, events while minimizing false positives.
Telemetry can be defined as the art and science of conveying information from one location to another. When you apply the acquisition of massive amounts of data via sensors to the effort of accurate measurement you find that the possibilities of biochemical-monitoring reach into new areas of possible knowledge.
