1. A sensor for electro-chemical analysis of a sample comprising:
- a top sheet having a top sample contact surface and a top sheet notch;
a bottom sheet having a bottom sample contact surface and a bottom sheet notch;
a spacer sheet between said top sheet and said bottom sheet and having first and second spacer sheet notches, said first spacer sheet notch aligning with said top sheet notch and said second spacer sheet notch aligning with said bottom sheet notch; and
wherein said top sample contact surface and said bottom sample contact surface form a sample fill area for receiving said sample, and wherein greater than about 50% of a perimeter of said sample fill area is accessible to receive said sample, andwherein said top sample contact surface also extends from a body of said top sheet by a top neck and wherein said bottom sample contact surface extends from a body of said bottom sheet by a bottom neck, and further wherein a volume defined by said top sample contact surface and said bottom sample contact surface and having a height approximately equal to the width of said spacer sheet is adapted to contain said sample.

Abstract
Sensors for the electro-chemical analysis of samples and methods for the manufacturing of sensors allow for more efficient manufacture and use of electro-chemical sensors. Flexible sheets, such as polycarbonate sheets, are used to easily manufacture sensor components, with sensor chemistry being applied to the sensor components at manufacture. Sensors may be manufactured with modular components, enabling easy production-line manufacture and construction of electro-chemical sensors with significant cost savings and increased efficiency over existing sensor styles and sensor manufacturing techniques.
