strain sensors have been favored by many researchers for their good flexibility, small size, light weight, and high conformability and have been initially explored for human health monitoring, human-computer interaction, and other fields. [7][8][9][10] The design and development of strain sensing materials are the core of flexible strain sensors. [11][12][13] With the concept of environmental protection and sustainable development deeply rooted, renewable, degradable, and natural fiber materials have become the more competitive materials to manufacture flexible strain sensors due to their low price, easy acquisition, and easy combination with textiles. [14][15][16] Natural fiber materials are mainly divided into cellulose fiber (cotton, fibrilia, and viscose) and protein fiber (wool and silk), which all show excellent softness and can be woven into yarn, nonwoven film, and 2D or 3D fabric with different structural characteristics. [17][18][19][20] The above materials can be directly carbonized or mixed with other conductive nanomaterials to construct flexible conductive networks. These green manufacturing materials have become an important trend to develop flexible strain sensors. [21][22][23] The carbonization temperature and time are the decisive factors for balancing the electrical conductivity and strain sensing performance of carbonized natural fiber materials. [24][25][26] Many studies found that although carbonized fibers exhibit excellent conductivity, they have a small strain range and high brittleness. Thus, they need to be combined with elastic polymers to improve their flexibility and strain capacity. [27][28][29] Original natural fiber materials can maintain excellent softness after they are combined with conductive nanomaterials, but they still exhibit major challenges, such as poor resilience, small strain range, poor wear resistance, and others. Therefore, they need to be combined with elastic polymers to improve the sensing performance. [30][31][32] The main polymer materials are polyurethane (TPU), polydimethylsiloxane (PDMS), and Ecoflex. The breaking elongation of the polymer determines the upper limit of the sensor strain range. The resilience, viscoelasticity, and fatigue resistance of the polymer are very important to the hysteresis, durability, and response speed of the sensor. The interfacial interaction between the polymer and conductive material affects the stability and sensitivity of the sensor. Conductive nanomaterials are diversiform, including carbon black (CB), carbon nanotubes (CNTs), graphene (GR), silver nanoparticles (AgNP), silver nanowires (AgNW), copper nanoparticles Flexible strain sensors with outstanding stretchability and sensitivity can be widely used in medical health, smart robot, intelligent garment, man-machine interaction, and other fields. The use of natural fibers enables a green manufacturing pathway to design strain sensors within the context of increasingly serious environmental pollution. Commercialized natural fibers, including cellulose fibers (cotton and ...

“…In order to provide accurate and semi-real-time information about performances and conditions of various civil engineering structures (buildings, bridges, roads, etc.) thick resistive films are being used as strain sensors because of their good strain sensitivity, stability, reliability and low manufacturing costs [1][2][3]. Since thick-film strain sensors for structural health monitoring are usually deployed on primary locations, such as columns, walls and ceilings of a building, research efforts have been directed to determining factors that can affect the gauge factor as the key parameter when strain sensors are in question.…”

This is important for structural health monitoring applications because of the day-night and seasonal temperature variations [2,[4][5].

In order to provide accurate and semi-real-time information about performances and conditions of various civil engineering structures thick-film resistors are often being used as strain sensors. For that purpose, Ba2Ru2O7 thick resistive films based on compositions with sheet resistivities of 1 kOhm/sq, 10 kOhm/sq and 100 kOhm/sq were evaluated. Resistors were fired at three different peak temperatures (825oC, 850oC and 875oC) and with three different dwelling times (5 min, 10 min and 15 min) in order to correlate influence of firing variables and thick resistive film strain sensitivity by tracking structure-related changes in resistance, gage factor and noise index values. For 10 kOhm/sq composition values of resistance change vs. temperature and temperature coefficient of resistance were measured and calculated.

“…3). В известной нам литературе [1][2][3][4] (а также в других работах, приведенных там) экспериментально и теоретически исследованы только участки I и II. Интерес к участку II обусловлен условиями применения в радиоэлектронной аппаратуре, к участку I -поисками подтверждения механизмов проводимости, основанных на туннелировании электронов между частицами лигатуры или на прыжках с переменной длиной между ними же.…”

Представление о псевдощели и нанокристаллах использовано для объяснения механизма электропроводности силикатного стекла, легированного оксидами переходных металлов (толстопленочные резисторы). Псевдощель возникает между потолком валентной зоны стекла и примесной зоной, созданной диффузией атомов лигатуры в стекло при спекании. Нанокристаллы образуются в стекле в процессе его варки, претерпевают структурные превращения при высоких температурах и действуют как центры локализации носителей заряда. Достигнуто качественное соответствие модели с экспериментальной температурной зависимостью проводимости легированного стекла в интервале от гелиевых температур до 1100 K. Ключевые слова: силикатное стекло, толстопленочные резисторы, легирование, туннелирование, нанокристаллы, псевдощель.
