Abstract

A garment preferably in the form of a body suit which carries one or more sensors for sensing bodily functions of a wearer of the body suit. The body suit preferably has stretchable sections or belts upon which the sensors are carried such that the sensors are maintained in proper position on the body for reliable detection of the body functions.

18. The garment of claim 1 in which said sensor (25, 26, 27, 28, 29, 30) is made of an elastomeric material (53) in which conductive particles (52) are embedded.

19. The garment of claim 18 in which said conductive particles (52) are carbon particles.

20. The garment of claim 18 in which said conductive particles (52) are carbon particles each having a diameter between 0.01 and 10 μ

m.

21. The garment of claim 18 in which said conductive particles (52) are conductive metal particles each having a diameter between 0.01 and 10 μ

m, and the metal of said particles includes at least one of the substances of Al, Cu, Ag, Fe, Ni, or Ti.

22. The garment of claim 19 in which said carbon particles comprise a volume of between 30 and 60% of the material of the sensor.

23. The garment of claim 1 in which said sensor includes an elastomer (53) that is a skin-tolerable material.

24. The garment of claim 1 in which said sensor includes an elastomer (53) that is a non-allergenic material.

25. The garment of claim 1 in which said sensor includes an elastomer (53) that is stretchable more than a substrate surface on which the sensor is placed on the body portion.

26. The garment of claim 1 in which said sensor includes an elastomer (53) that is one of a fluoropolymer, polyurethane or silicone.

27. The garment of claim 1 in which said sensor (29, 30) has an insulating layer (51) on a single side thereof.
