These opportunities are illustrative of a process of matching technologies to needs to determine application opportunities and of matching needs to technologies to determine gaps in capabilities. They are not prioritized and are only representative of the cases examined by the committee. Sensors currently used to monitor the curing of thermosetting resins have serious shortcomings. The principal opportunities lie in developing sensor systems that can measure, in real time, several different microstructural parameters of the curing materials without requiring a number of separate sensors.
Photon-scattering sensor technology has the potential to satisfy many of these needs cost-effectively. The near-term research opportunity involves extending this.

The journal aims to promote original works that demonstrate significant progress beyond the current state of the art in these fields along with applicability to solve meaningful analytical problems. Review articles may only be submitted upon invitation from an Editor of the journal. The journal aims to publish works that are supported by experimental results and as such purely theoretical works are not accepted. The analytical performance in all analytical parameters needs to be reported and critically compared with the state of the art. Sensing applications will be considered only if they refer to analytically challenging complex samples and are properly validated. Types of paper Sensors and Actuators B: Chemical, publishes full length research papers and review articles, and short communications.

History has shown that advancements in materials science and engineering have been important drivers in the development of sensor technologies. For instance, the temperature sensitivity of electrical resistance in a variety of materials was noted in the early s and was applied by Wilhelm von Siemens in to develop a temperature sensor based on a copper resistor. The high resonance stability of single-crystal quartz, as well as its piezoelectric properties, have made possible an extraordinarily wide range of high performance, affordable sensors that have played an important role in everyday life and national defense. More recently, a new era in sensor technology was ushered in by the development of large-scale silicon processing, permitting the exploitation of silicon to create new methods for transducing physical phenomena into electrical output that can be readily processed by a computer. Ongoing developments in materials technology will permit better control of material properties and behavior, thereby offering possibilities for new sensors with advanced features, such as greater fidelity, lower cost, and increased reliability.
The four most common types of temperature sensors, ranging in responsiveness and accuracy from high to low are:. A thermistor is a thermally sensitive resistor that exhibits a continuous, small, incremental change in resistance correlated to variations in temperature. An NTC thermistor provides higher resistance at low temperatures. As temperature increases, the resistance drops incrementally, according to its R-T table. The output of an NTC thermistor is non-linear due to its exponential nature; however, it can be linearized based on its application. An RTD consists of a film or, for greater accuracy, a wire wrapped around a ceramic or glass core. Platinum makes up the most accurate RTDs while nickel and copper make RTDs that are lower cost; however, nickel and copper are not as stable or repeatable as platinum.
Sensors science and engineering is relevant to virtually all aspects of life including safety, security, surveillance, monitoring, and awareness in general. Sensors are central to industrial applications being used for process control, monitoring, and safety. Sensors are also central to medicine being used for diagnostics, monitoring, critical care, and public health. What is exciting in sensor research and development today? That is a tough question.
