Abstract
Ordinary inexpensive magnetic recording tape is used to create a novel resistance element which may be made pressure sensitive to perform a number of tasks involving robot finger control intrusion alarm systems, and portable weighing scales. A pressure insensitive resistance element is also used as an efficient, inexpensive heating tape element, or to make precision resistors having little bulk, and resistive networks which may be customized by a user.
