This weekly report summarizes the progress of a student group working on a smart kettle project. The group studied touch sensors to add an interactive element to the kettle. They looked at tactile and flex sensors and how they output signals when touched or bent. The report notes the sensors allow adjusting sensitivity but does not know their temperature tolerance. The group's job for next week is to design part of the kettle's circuit.

Weekly Progress
This week we was present Aj.Yap and Aj.Pot about our function of kettle. They advise
more function to us. So we think a kettle should have interested connection with user. Kettle
will has touch screen for touch to turn on and do something more. So this week I was study
about “touch sensor” it is a device provide a signal output when it is exposed. The simple of
this sensor is a micro switch is turn on or off when touched. Another sensor is “tactile
sensor” it can measure the exposure and show data off object. Flex sensor has a certain
flexibility used to measure the bending of the substrate and the output signal on a twist
because resistance has change.

Engineering Analysis
Strong Point
- We can adjust the sensitivity or rang of motion.
Weak Point
- I don’t know can it tolerate temperature.
Next Week Job
- Design some part of kettle’s circuit
