+# Overview
+
+In order to begin [biomaterials](:Category:Biomaterials "wikilink")
+testing, GrindDC needs a realistic implant test platform. The
+implantable cardiac pacemaker was chosen as the first project because it
+is:
+
+- easily implemented
+- cheap to produce
+- small
+- can easily utilize inductive power
+
+# Status
+
+Implant is early in the design phase.
+
+# Goals
+
+## Inductive Power
+
+Inductive power is a core feature that will be implemented in all future
+designs for primary power or recharging of implanted power supply.
+
+The pacemaker test platform should implement:
+
+- inductive power recharge (with battery)
+- inductive power only operation (without battery)
+- easily replaced inductors
+
+## Small Size / Inexpensive
+
+To accomplish the [biomaterials](:Category:Biomaterials "wikilink")
+testing goals the pacemaker reference implant will need to be small in
+area to facilitate cheap production of the printed circuit boards.
+Additionally, the required parts should be minimized in number and cost.
+
+## Functional
+
+Using a simulated cardiac cell model, the pacer should regulate the
+circuit when Artrial-Ventricular block is simulated. The chosen cardiac
+model is described in *Synchronization with low power consumption of
+hardware models of cardiac cells* (Maeda, Yagi, Makino;
+2005[1](http://dx.doi.org/10.1016/j.biosystems.2004.09.005)).
