Abstract: A tensile stress measurement device is to be attached to an object to be measured. The tensile stress measurement device may include an IC having a semiconductor substrate and tensile stress detection circuitry, the semiconductor substrate having opposing first and second attachment areas. The tensile stress measurement device may include a first attachment plate coupled to the first attachment area and extending outwardly to be attached to the object to be measured, and a second attachment plate coupled to the second attachment area and extending outwardly to be attached to the object to be measured. The tensile stress detection circuitry may be configured to detect a tensile stress imparted on the first and second attachment plates when attached to the object to be measured.

Abstract: An integrated electronic device 1 for detecting at least one parameter related to humidity and/or presence of water and/or acidity/basicity of an environment surrounding the device is described. Such device 1 comprises a separation layer 14 from the surrounding environment, comprising at least one portion of insulating material 14, and further comprises a first conductive member 11 and a second conductive member 12, made of an electrically conductive material, arranged inside the separation layer 14, with respect to the surrounding environment, and separated from the surrounding environment by the separation layer 14. The device 1 also comprises a measurement module 15, having two measurement terminals 151, 152, electrically connected with the first 11 and the second 12 conductive members, respectively; the measurement module 15 is configured to provide an electric potential difference between the first 11 and the second 12 conductive members. The device 1 further comprises electrode means 13, configured to act as an electrode, arranged outside of the separation layer 14, with respect to the first 11 and the second 12 conductive members; the electrode means 13 are arranged so as to form, with the first 11 and the second 12 conductive members, an electromagnetic circuit having an electromagnetic circuit overall impedance variable based upon the exposure to environmental conditions with a variable level of humidity and/or acidity/basicity. The measurement module 15 is configured to measure the electromagnetic circuit overall impedance, which is present between the measurement terminals 151, 152, and to determine the at least one parameter to be detected, based on the overall impedance measured.
