The perfect sensor system
• Measures everything• Everywhere• Online• Cheap• Processes it’s data• Converts the signal in understandable
message

The dilemma in real life
• 1 expensive sensor which measureseverything
• Many cheap sensors which measureeverywhere
5125
Most wetsus sensor development
• Early warning systems
• Respond to a class of compounds rather than to a single substrate
• Fingerprinting
• Online
