A key challenge is…
• …deciding which sensor project/system todesign and build
![Page 3: PANEL Sensing Everything: Challenges in Current Environments€¦ · Research GE Businesses Idea/discovery Feasibility Tech transfer NPI Product maturity Nanostructured ... 1914 1950-70s](https://reader034.fdocuments.net/reader034/viewer/2022051409/6015099b15d66e1caf018203/html5/thumbnails/3.jpg)
Some criteria for judging opportunitiesand performance
• Accuracy
• Initial cost
• Operation cost
• Total lifetime cost
• Power requirements
• Sensitivity
• Size
• Stability
• Application-specificversus general-purpose
• Ability to integrate withexisting sensors or othersystems
• Market size
• Competition fromalternative sensingmethods
• Adoption risk
• Technology “push” versusmarket “pull”
