5.44 Flexiforce pressure sensor

Pressure sensor

Pressure sensors, shown in Fig. 5.44, are perfect for measuring
forces. The “sensor” portion on the sensor is contained in the 14
mm 14 mm pad at the end of the sensor. The resistance of the
sensor decreases as force is applied. There are a variety of pres-
sure ranges available from 0 to 1 pound (lb) up to 0 to 1000 lb.

Smell

Currently no sensor exists that can approach the olfactory sense
of the human nose. What is available are simple gas sensors that
can detect toxic gases (see Fig. 5.45). The gas sensors can be used
to create automatic (robotic) ventilation systems.
