INTRODUCTION
• The measurand is first detected by the primary sensing element.
• The nrising demand for automation,security and comfort leads to completely new sensor applications.
• The number of sensor systems required and the diversity of the application is permanently increasing.
• Nowadays, sensor technology introduces in new application fields and mass markets like automobiles or smart homes.
SENSOR DESIGN
1. In the design process the technical and economical consideration of the target application are generally necessary.
2. The specific requirements and boundary conditions are useful for the concrete specification of the sensor system which the design of the sensor system bases.
3. Simulation techniques are usually used in order to considerably shorten the sensor time-to-market and to improve the sensor properties during the design process.
4. SENSOR DESIGN
FUTURE TRENDS IN SENSOR TECHNOLOGY
• The main development trends in sensor technology go towards miniaturization and an increasing use of multi-sensor and wireless systems.
TREND TO MINIATURIZATION: microsystem Technology.
• Miniaturization is an outstanding strategy of success in modern technologies.
• It reduces production costs and increases performance by integration of microcomponents.
• Miniaturization is gaining importance in all fields of application where smaller structures and greater precision are becoming decisive to the market acceptance of individual products.
• For the monitoring of vital parameters of human beings, health care devices can be used, so that an emergency call could be released automatically in case of unconscious-ness of the person.
TREND TO THE USE OF MULTI-SENSORS
• The use of multi-sensor systems is becoming more important in widespread application fields.
• their applications reach from the monitoring and automation of manufacturing process to robotics, automotive applications,smart homes, process control, environmental engineering, biotechnology and life sciences.
• Energy autonomous sensors will gain a particular importance among wireless sensors, because in this case no wires are necessary anymore for electricity supply.
