CE2020 Chemical Sensing 7.5 credits

The paradox of sensing any particular chemical event in our surroundings is probably one of the key innovative and challenging directions towards a sustainable world. What makes this challenge very exciting is the possibility of obtaining decentralized and digitalized chemical information in very efficient and trustable manner by utilizing chemical sensors with extraordinary features never seen before (e.g., implantable, submersible, miniaturized, low-cost, simple, paper-based among others). Tangible benefits to the society with efforts put into the democratization of the chemical information are expected outcomes that will not only ensure better quality of life, but also a deep understanding of ongoing chemical process.

This course builds solid knowledge on the working basis of chemical sensors (mainly electrochemical and optical sensors). In particular, most relevant sensors will be illustrated by the most recent scientific literature in fields such as healthcare, environmental, clinical analysis and quality control. In terms of sustainable development (SD), to what extent are chemical sensors an important piece of technology that pursues social, economic and environmental sustainability will be discussed in each module.  

After passing the course the student should be able to:

• Describe the diverse functioning modes of chemical sensors, their fundamental principles as well as derive useful relationships on how the sensor signal depends on different parameters.
• Demonstrate an ability to find alternative scenarios to address current sensing challenges and explain the importance of chemical sensors in the digital transformation and its relation to social, economic and environmental sustainability.
• Describe the fundamental methodology for experiments based on chemical sensors as well as perform simple experiments with them.

Bachelor's degree in engineering or in sciences including 50 credits in chemistry or chemical engineering, English B/6.

If the course is discontinued, students may request to be examined during the following two academic years.

• LAB1 - Laboratory work, 3.0 credits, grading scale: P, F
• TEN1 - Written exam, 4.5 credits, grading scale: A, B, C, D, E, FX, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.
