A Microcalorimeter for Nondestructive Analysis of Pacemakers and Pacemaker Batteries

Abstract

A microcalorimeter has been built by the authors and used to measure internal losses in primary pacemaker batteries. Power dissipation of 10-50 ¿W has been measured in new pacemaker batteries, much of which is traceable to innocuous exotherm from continuing curing of plastic materials in the battery. True internal shorts have produced 1000-2000 ¿W of heat… (More)
