“…This has been demonstrated so far using triboelectric, photovoltaic, piezoelectric, radiofrequency, thermoelectric (TE) systems, and others . In the case of TE technology, conventional systems have been considered as a power source for integrated sensors of pressure, corrosion, heat flow, vibration, heart rate, and other stimuli . The utilization of conjugated polymers as the active component of a TE device is a relatively recent concept, but it is rather attractive where flexibility is needed, enabling a new generation of novel, low‐cost, low‐powered wearable, or even remote, sensors.…”

The development of new flexible and stretchable sensors addresses the demands of upcoming application fields like internet-of-things, soft robotics, and health/structure monitoring. However, finding a reliable and robust power source to operate these devices, particularly in off-the-grid, maintenance-free applications, still poses a great challenge. The exploitation of ubiquitous temperature gradients, as the source of energy, can become a practical solution, since the recent discovery of the outstanding thermoelectric properties of a conductive polymer, poly(3,4-ethylenedioxythiophene)poly(styrenesulfonate) (PEDOT:PSS). Unfortunately the use of PEDOT:PSS is currently constrained by its brittleness and limited processability. Herein, PEDOT:PSS is blended with a commercial elastomeric polyurethane (Lycra), to obtain tough and processable self-standing films. A remarkable strainat-break of ≈700% is achieved for blends with 90 wt% Lycra, after ethylene glycol treatment, without affecting the Seebeck voltage. For the first time the viability of these novel blends as stretchable self-powered sensors is demonstrated.

“…Pyroelectric current can be used not only for temperature measurement sensors but also for waste energy harvesting. Any source of waste energy with temperature changes over time is suitable to produce pyroelectricity and can be harvested for many applications [12,[14][15][16][17]…”

Temperature measurements from a power generation system could improve its overall safety and efficiency. In addition, real time temperature measurement could lead to a qualitative assessment of the health of the energy system. The challenge of real time temperature measurement inside of a power generation unit lies in the sustainability and the reliability of sensing materials in high temperature and corrosive environments. In this paper, a pyroelectric ceramic material (Lithium Niobate, LiNbO 3) capable of sustaining high temperatures, is considered as the temperature sensing material. LiNbO 3 is a pyroelectric material that generates current proportional to the rate of temperature change with time. This property is sustained by LiNbO 3 until it reaches its Curie temperature (1210 °C). The generated current could be used for many applications including temperature sensing and energy harvesting from waste heat recovery. This paper presents the temperature measurement results using a LiNbO 3 pyroelectric ceramic. Ceramics with dimensions of 1 cm x 1 cm with two different thicknesses, 2 mm and 1 mm, were used as the temperature measurement sensors. Two samples were heated by a 14.5 W/cm 2 heat flux and cooled with natural convection. Electrodes were made on both surfaces of the samples with high purity silver paint and two electrical leads were connected to a picoammeter to measure the generated current with respect to the rate of temperature change of the material during heating and natural cooling. A K-type surface thermocouple was attached on top of LiNbO 3 to compare the temperature measurements and maximum 8 % and 6.7 % differences were found for 2 mm and 1 mm thick samples, respectively.

“…The sensors can detect the structural corrosion timely and avoid unnecessary losses. As the technology is applied to sensors in different environments, structural locations and metal matrix with different properties, different types of corrosion sensors have been studied [9,10,11,12,13,14]. There are many kinds of corrosion sensing technology.…”

Corrosion damage to the aircraft structure can significantly reduce the safety performance and endanger flight safety. Especially when the corrosion occurs in a stress concentration region, such as hole edges, it can easily threaten the entire structure. In this paper, an on-line imaging qualitative monitoring algorithm based on piezoelectric sensors is proposed for detecting hole edge corrosion damage of porous aluminum alloy structures. The normalized amplitude is used to characterize the correlation between the initial Lamb wave signal and the damage signal, which is as an image reconstruction parameter in the algebraic iterative probability reconstruction algorithm. Moreover, a homogenization algorithm is proposed to process the reconstruction results. The experimental results of single hole and double hole corrosion for porous aluminum alloy plate show that the method can effectively achieve the location and quantification of corrosion damage to one and two holes of the porous structure.
