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. <img src='prior/milled.jpg' width=33%> <img src='prior/settingup.jpg' width=39%> +It is based on a discrete electrostatics solver (shown below), and also documented on the page above. + <img src='prior/moving-dialectric.mp4' width=400px>
