NTT Corporation of Japan announced on February 12 that it has developed materials for electrodes that can be embedded in clothing such as underwear. The material developed on the surface of silk or synthetic fiber coated with conductive polymer "PEDOT-PSS" is soft, hydrophilic and high-strength, and is biocompatible and close to the skin. It also does not cause a rash or discomfort.
NTT said that in the past, when measuring ECG, it was common to apply a paste or gel electrolyte on the electrode, but "this will cover the sweat glands, making people feel uncomfortable and difficult to use for a long time." Moreover, although there are silver-plated fibers in the fibrous material, the interference is large and the electrocardiogram cannot be measured.
NTT has tested new materials and allowed 10 healthy people to wear them for several days, including more than 24 hours of continuous wear. It has been confirmed that data can be continuously obtained without causing a rash caused by the material. In the future, we will conduct a wear test for 100 people and further carry out safety verification. We will also cooperate with the University Medical Department and research institutes to plan for long-term ECG measurement, monitoring, basic research, home and telemedicine, etc. within 2 years. Clear roads in the field.
NTT also said: "This material can be hand-washed, but it is difficult to wash with a washing machine. This is a problem that needs to be solved in the future." This material can be used not only for ECG measurement, but also as an electroencephalogram detection electrode. Moreover, it has high biocompatibility, so it can be directly implanted around the nerve to measure nerve activity potential.

Venlo structure is a popular one at present. This architecture uses horizontal girder as main bearer, forming a stable structure with columns. There is consolidation between horizontal girder and column, and hinge is used to connect column and foundation.
In Venlo greenhouse, foundation is made of reinforced concrete and the side wall is made of brick or reinforced concrete plate. The steel frame always use hot dip galvanized light steel. Roof beam adopts horizontal girder structure and using herringbone connection. The horizontal girder bears 2 or more roofs, which is made of aluminum alloy. This material is used as roof structure material and also glass inlay material. Other beams using gutter style to minimize the section. Delighting material of the roof and side wall using the hollow double-layer or multilayer PC board.
PC board is mainly made of PC/PET/PMMA/PP materials, it need sun screen coating to resist ultraviolet resist and ageing, and it is also required to be anti condensation and antidrug.
As a kind of light material, use PC board can greatly reduce the weight of greenhouse structure, and corresponding reduced the size of the steel frame, which saving the cost of steel.
