In association with our TTT
sponsor Schott Glass,
we have launched several different projects that look at sensing and actuating
in glass-ceramic cooktops. In particular, our studies have encompassed:
- A continuous capacitive slider for controlling burner heat (in contrast
with the increment-decrement buttons that are now ubiquitous). See a
video clip of our prototype in action here
- UltraLowPower, quasipassive wakeup of sleeping cooktop electronics.
- In-glass haptic response for capacitive button presses (note that
this work has been taken further by the Palpable
Machines Group at the Media Lab Europe).
- Remote temperature monitoring of the cooktop glass above the burners
using passive IR emission and active acoustics.
- Pot detection and characterization via electric field sensing.
