An adhesive strain sensing pod includes at least one strain sensor, electronics for electrically sensing at least one strain signal from the at least one strain sensor, and a sensor adhesive for adhering the strain sensor to a surface of a structural element. The pod may have a protective case for protecting the strain sensor and the electronics and for transferring at least part of a force, pressing the pod against the surface, to press the strain sensor against the surface. The sensor adhesive may be a liquid adhesive contained in a fragile pouch that ruptures when the pod is forced against the surface, or may be a thermally activated adhesive film that is activated to bond the strain sensor to the surface. A protective film may protect the sensor adhesive prior to installation of the pod and is removed prior to installation of the pod on the surface.
