Online Sensor presentation

o Pick one of the sensors that you are using in your group project.

o FSR: force sensing resistor

o How does it work?

o Force Sensing Resistors (FSR) are a polymer thick film (PTF) device which exhibits a decrease in resistance with an increase in the force applied to the active surface

o What different flavors does it come in?

o Shapes.

o What are its practical applications outside of art making?

o Human touch control in electronic devices

o Find as much information about that sensor as possible.

o http://www.media.mit.edu/resenv/classes/MAS836/Readings/fsrguide.pdf

o Locate the schematic.

o the top image is.

o Find the inputs, outputs, how to calibrate or impact the use and other relevant information on the diagram.

o Input is the force applied; Output is the voltage; RM can be of 3k, 10k, 30k, 47k and 100k and these different RMs correspond different output sets. The amplifier is another factor

o What are its power requirements and what sorts of other electronics are necessary to get it to work.

o 5v power supply and a resistor are necessary.

o Label the diagram and explain to us how to use the sensor.

o In my case, the amplifier is integrated in arduino and 10k resistor is good for my output range.

o Tell us how the sensor is typically used. Tell us how you plan to use and/or modify the sensor.

o According to the FSR guide, this sensor is not for weight and probably can be better used for human touching. In my situation, Repeatable and Reproducible Mechanical Actuation System is the CRUTIAL part.
