“…A pressure sensor wedged between the pressure garment and the skin can directly measure the pressure. So far, multiple types of pressure sensors have been invented, such as the electron-pneumatic pressure sensor, 35,36 fluid-filled pressure sensor, 37 pneumatic pressure sensor (eg, Kikuhime pressure sensor), 29,38 and capacitive sensor (eg, the Pliance X system). 39,40 Nevertheless, most of these sensors are defected by insufficient accuracy, inconvenient processing, and high expense, all refraining their wide use in clinical practice.…”

Background Pressure Garment Treatment (PGT) is currently recognized as an effective method to prevent scar formation or treat scar hyperplasia. Research on PGT remains controversial. These controversies indicate that PGT lacks reliable evidence of evidence-based medicine. Different studies on PGT need to be conducted under the same ‘gold standard’ so that different studies can be compared. We consider this ‘gold standard’ to be that the pressure remains stable within a confidence interval during treatment. Methods We calibrated and verified the reference value of the sensor using a cuff of sphygmanometer.A pressure adjustable pressure system was obtained by installing a soft tissue expander on the pressure garment.Local pressure was adjusted by charging and releasing air.Subsequently, the flexible pressure sensor was placed on the upper arm of the healthy volunteers. We validated the compression system on healthy volunteers' forearms and AO standard prostheses (forearms). Results Reference value of the sensor was calibrated on No.1 volunteer. Measuring repeated on No.2 and No. 3. The measurement was very reproducible. The test results in the experimental group showed that the local pressure gradually increased with the increase of the inflation of the airbag. However, the pressure at the opposite position of the forearm changed little. Conclusions Real-time pressure monitoring and pressure adjustment enable the pressure to be maintained at a certain value. Our study provides a new idea for the production of elastic clothing with the function of pressure measurement and pressure regulation, which may promote the accuracy and reliability of PGT.

Background: Hypertrophic scars are one of dermal fibroproliferative disorders which can lead to pruritus, disfigurement and pain. The use of microneedling to introduce topical agents or drugs into the dermis is a rapidly growing and popular skin/scar treatment.Patients and Methods: This is a prospective randomized study that included 30 patients suffering from Hypertrophic scars and they are candidate for the proposed technique. Microneedling by Dermapen device with application of topical triamcinolone acetonide solution on scar tissue for three sessions with 3 weeks interval in between.Results: During one year, 30 patients were recruited in our study, the mean age of the patients was 28.16±11.24 (range 21-58 year) and 52% of patients were female. Lesions location were anterior chest (8), extremities (18) and back (4). Mean zero VSS scores were achieved with triamcinolone transepidermal injection in respect of scar height (week 15 th ) and pliability (week 15 th ). Conclusion:Our results did support the capability of triamcinolone transepidermal injection using Dermapen in treatment of hypertrophic scars, with an efficient, less painful and cost-effective procedure.

“…Use of compression textiles to apply continuous and steady pressure in medical treatment such as for hypertrophic burn scars dates back to the 1970s. , To ensure treatment efficiency, researchers tried to accurately measure the pressure generated by compression textiles on the human body. , One approach is calculating the pressure through the fabric tension by Laplace’s Law. , With the development of yarn and fabric strain sensors, − the ones using carbon nanotubes or electrospun fibers can be seamlessly interwoven into the fabric, which converts fabric strain into electrical outputs like resistance change. − In order to build up the link between the electrical output and pressure, studying the pressure behavior of the fabric under compression is crucial for measurement accuracy. Moreover, as the working principle of the yarn sensor is based on its deformation along with the fabric, it is essential to choose the proper base fabric structure for yarn sensor integration.…”

Using compression textiles to exert an appropriate and steady pressure on human limbs is a primary treatment method in the medical area. Compression pressure is a crucial parameter that determines the treatment efficacy. However, there is a lack of pressure-sensing fabrics that can both apply and measure the pressure of compression textiles, particularly the theoretical study of the prediction of the pressure and sensing performance of such a sensing fabric. In this study, based on the developed elastic pressure-exerting and -sensing fabrics and a setup test protocol simulating the pressure-exerting process, the relationships between the displacement of the press head, resultant fabric extension, and pressure were theoretically explored. Two finite element (FE) models, continuum and discontinuous models, were first established to predict the pressure behavior of elastic pressure-exerting and -sensing fabrics. The simulation results present good agreement with the experimental results wherein the pressure generated increases with the increase of the fabric strain in a nonlinear form. Furthermore, with the above FE models for the relationship between fabric extension and pressure generated, as well as the measured electrical resistance of the sensing fabric, a model for the electrical resistance of the sensing fabric can thus be established. Among pressure-sensing fabrics in three different structures, the sensing fabric in sateen exhibits better pressure prediction accuracy and a faster response to the pressure change. Finally, a series of numerical simulations were conducted to investigate the effects of the press head diameter, the unit cell crimp factor of fabric and the fabric pretension on the fabric extension, the resultant pressure, and electrical resistance change. The simulation results show that the pressure decreases with the increase of the press head diameter. The crimp factor and pretension of the sensing fabric also have a significant effect on the pressure and electrical resistance change generated. This simulation approach provides a new theoretical understanding of the pressure behavior and mechanism of pressure-sensing fabrics for future smart compression textiles.
