From: Artificial olfactory sensor technology that mimics the olfactory mechanism: a comprehensive review
Sensor type | Strengths | Weaknesses |
---|---|---|
High sensitivity, target diversity, short response time, easy to dissociate, convenient replacement | High energy required, inaccurate readings (sensor drift), controlled environment, controlled setting (vacuum), streaky fabrication | |
High sensitivity, target diversity, short response time, diverse range of coatings, concise configuration | High cost, high energy required, complex circuitry, commercialization, controlled temperature, reproducibility | |
High sensitivity, short response times, low cost, room temperature operation, diverse range of coatings | Low durability (weak), inaccurate readings (sensor drift), complex synthetic process | |
Excellent intuition, small, no external power required, portable, convenient | Low sensitivity, complex manufacturing process | |
Excellent intuition, small, no external power required, portable, convenient, high sensitivity, high selectivity, wide compatibility, eco-friendly | Lack of standardization, limited mass production | |
Very high sensitivity, low energy consumption, individual response (compounds mixture analysis), quick response. | High cost, complex construction, difficult to make portable system | |
Short response time, high sensitivity and stability, enables qualitative and quantitative analysis, universal detector | High cost, complex construction (spectrometer), response time, difficulty of field analysis |
