MC2 Post 944 Paper Accelerometers for Pennies in the Works


[George Whitesides] led a team to develop the new technology that uses simple manufacturing methods to produce the sensor seen above. Graphite and silver inks were screen printed onto heavy paper. The single limb sticking out from the body of the sensor is a separate piece of paper that bends the carbon area when force is applied. This changes the carbon’s resistance which is measured using a Wheatstone bridge constructed by gluing resistors to the device.


Thinking of Hardware Hacking? 

Let's Go to the Board Room:

Hackaday has compiled a list of boards that we commonly 
see in submitted projects, split up by price range and 
with a little detail for reference.
