Provided are a stretchable humidity-sensitive composite material for a humidity sensor that can be applied to clothing as wearable device, and the humidity sensor. The humidity-sensitive composite material is characterized by containing a deliquescent inorganic compound in closed pores inside a base material made of a porous silicone resin. The humidity sensor is characterized in that a bulk made of a humidity-sensitive composite material containing a deliquescent inorganic compound in closed pores inside a base material made of a porous silicone resin is sandwiched between a pair of counter electrodes made of a moisture-permeable material.

Humidity-sensitive composite material and humidity sensor

A microwave heating method using a microwave, including: controlling a frequency of the microwave, to form a single-mode standing wave; disposing an object to be heated in a magnetic field region where a strength of a magnetic field formed by the single-mode standing wave is uniform and maximum; and heating the object to be heated by magnetic heat generation by magnetic loss caused by an action of the magnetic field of the magnetic field region, and/or induction heating by an induced current generated in the object to be heated due to the magnetic field of the magnetic field region.

A stretchable electrically-conductive sheet according to the present invention includes an elastomer sheethaving an adhesive layer corresponding to a wiring region with a predetermined pattern formed on a front surface of the elastomer sheet, and also includes electrically-conductive fiber materialseach having a predetermined diameter and a predetermined length. When the elastomer sheetis stretched or bended, the electrically-conductive fiber materials relatively move maintaining mutual electrical continuity so as to maintain the electrical continuity in the wiring region. Accordingly, it is possible to achieve a low-cost stretchable electrically-conductive circuit having excellent stretchability, bendability, and durability.

Disclosed is a process for producing a silicon oxide or silicon oxynitride thin film having a high level of water vapor and oxygen barrier property and a high strength with a higher efficiency by a solution process which is advantageous in productivity. Also disclosed is a thin film that is obtained by the process and is useful, for example, as a protective film for electric elements such as organic EL elements. A solution containing a smectite group silicate layered compound and a silazane compound is coated onto a surface of a substrate by a liquid phase process to form a film. The thin film thus obtained is exposed to ultraviolet light under an oxygen atmosphere to produce a silicon oxide thin film or a silicon oxynitride compound thin film containing the smectite group silicate layered compound. The smectite group silicate compound is a material represented by the following general formula.ABSiOHO&#x2003;&#x2003;[Chemical Formula 1]
