 # Loadcells
 
+Measuring displacement of a point or surface, rather than measuring the deformation of a flexure, offers many possibilities for compact, low-cost load cells.  This page gathers some resources on this topic and presents work towards a simple six degree-of-freedom (DOF) loadcell based on these ideas.

 ## Capacitive
 
-<a href='http://fab.cba.mit.edu/classes/862.16/people/sam.calisch/project/index.html'>3 DOF Capacitive load cell.</a>
+One way to determine the proximity of two surfaces is by measuring the capacitance between them.  <a href='http://fab.cba.mit.edu/classes/862.16/people/sam.calisch/project/index.html'>This page</a> documents experiments with a 3 DOF Capacitive load cell using a single printed circuit board.

+It is based on a discrete electrostatics solver (shown below), and also documented on the page above.
