摘要: A method of determining a condition within a wellbore. The method comprises introducing a tubular member in a wellbore extending through a subterranean formation, the tubular member comprising a downhole article including a deformable material disposed around a surface of the tubular member, electrically conductive elements dispersed within the deformable material. The method includes measuring at least one electrical property of the deformable material. At least one of water ingress into the wellbore or an amount of expansion of the deformable material is determined based on the at least one measured electrical property. Related downhole systems and other related methods are also disclosed.

摘要: A material removal process referred to as spalling is used to provide flexible and stretchable sensors that can be used for healthcare monitoring, bio-medical devices, wearable electronic devices, artificial skin, large area sensing, etc. The flexible and stretchable sensors of the present application have high sensitivity that is comparable to that of a bulk silicon sensor. The flexible and stretchable sensors comprise single crystalline spring-like structures that couple various resistor structures together.
