Physiological sensor device
First Claim
1. A physiological sensor device for attachment to a mammalian subjects comprising first and second regions of sensors attachable to a subject in use, said first and second regions of sensors being separated by a flexible web adapted to enable variable separation of the first and second sensor regions from one another in use, at least one of said first and second regions of sensors including at least two sensors aligned along a common transverse axis and having respective edges separated in a direction along said common transverse axis only by a slot, said slot defining the edges of the respective sensors.

Abstract
A physiological sensor device for attachment to a mammalian subject including first and second regions of sensors attachable to a subject in use, which first and second regions of sensors are separated by a flexible web adapted to enable variable separation of the first and second sensor regions from one another in use. The physiological sensor device is manufactured by forming a strip of electrically conductive material on a flexible electrically non-conductive substrate and cutting a slot through both the flexible substrate and conductive strip to define a pair of adjacent edges of conductive material separated by a non-conductive gap thereby also to define adjacent electrode sensors each having one of the pair of adjacent edges formed in the strip of conductive material. The physiological sensor device is attached to the subject for measurement of numerous physiological parameters for a period of time, such as 24 hours, and is then thrown away.
