Title
(EN) SELF-POWERED MINIATURE MOBILE SENSING DEVICE
(FR) DISPOSITIF DE DÉTECTION MOBILE MINIATURE AUTO-ALIMENTÉ
Abstract
(EN)
A device for wirelessly monitoring well conditions includes a power including a first material attached to edges of at least one lever suspended about a central fulcrum, wherein the edges of the at least one lever are free to move about the central fulcrum, a frictionless movable object disposed inside the body of the at least one lever, wherein the frictionless movable object is free to move within the body of the at least one lever, and a second material that is fixed in position relative to the first material, wherein the first material and second material are of opposite polarities.
(FR)
La présente invention concerne un dispositif permettant de surveiller sans fil des conditions de puits, ledit dispositif comprenant une puissance comprenant un premier matériau fixé à des bords d'au moins un levier suspendu autour d'un point d'appui central, les bords du ou des leviers étant libres de se déplacer autour du point d'appui central, un objet mobile sans frottement disposé à l'intérieur du corps du ou des leviers, l'objet mobile sans frottement étant libre de se déplacer à l'intérieur du corps du ou des leviers, et un second matériau qui est fixé en position par rapport au premier matériau, le premier matériau et le second matériau étant de polarités opposées.
