This review delves into the growing field of flexible and stretchable strain sensors utilized in human gait analysis, focusing on determining knee bending angle and muscle activities when a human subject walks. Recent advancements have enabled these sensors to accurately capture biomechanical parameters while accommodating the body's natural movements. We examine the principles underlying these sensors' design and fabrication techniques, emphasizing their flexibility, stretchability, and biocompatibility for seamless integration into wearable systems. Through critical evaluation of existing methodologies, we assess the reliability and validity of these sensors in quantifying gait parameters. Furthermore, we discuss this technology's clinical and research implications, highlighting its potential in personalized rehabilitation and sports performance optimization. We provide an overview of flexible strain sensors and their application for analyzing human walking gait, especially for observing walking gait in rehabilitation programs. First, we present the basic working principles of various flexible strain sensors. Second, by the application of flexible strain sensors as walking gait monitoring. Finally, current challenges and future opportunities in this research area are discussed. By synthesizing current knowledge and outlining future directions, this review aims to provide insights for researchers and practitioners seeking to leverage flexible and stretchable strain sensors for comprehensive human gait analysis.

With the widespread adoption of green and sustainable development concepts, enhancing the sensing performance of flexible pressure sensors while reducing manufacturing costs and environmental pollution has emerged as a pressing research issue. Drawing inspiration from bamboo, a naturally occurring green plant, we utilized virgin bamboo pulp as the raw material for producing draw paper. The resulting bamboo cylinder structure serves as the dielectric layer. We propose an extremely low-cost, user-friendly, and sustainable origami method for fabricating paperbased sensors. The structural parameters of the sensor were thoroughly investigated and optimized through finite element simulations and practical experiments. Notable features of the sensor include high sensitivity (1.96 kPa −1 within 0−50 kPa), a low detection limit (2 Pa), a wide pressure detection range (0−500 kPa), rapid response and recovery times (40 and 45 ms, respectively), and reliable durability and stability (∼5000 cycles). Experimental results demonstrate the successful application of these sensors in areas such as human motion, health monitoring, and human−computer interaction. The potential applications of sensors extend to flexible wearables, smart healthcare, human−machine collaboration, and electronic skin (e-skin).

Laser induced graphene (LIG), prepared directly with an in situ synthesis method onto Kraft Paper substrates, is proposed for the manufacture of biodegradable electronic devices. The investigation explores the influence of laser power and scanning speed on the properties of LIG conductive tracks and a sheet resistance of up to 0.25 kΩ sq−1. Raman spectroscopy and microscopy is used to analyse the interfacial properties, in particular the transition of cellulose fibers to carbonized graphene flakes through photothermal pyrolysis, leading to the formation of coral‐like structures. To demonstrate the applicability of the approach, flexible resistive heaters have been manufactured and tests show rapid heating with a homogeneous distribution and a maximum temperature of 145.5 °C. Additionally, an electro‐thermal conversion efficiency (hr+c) of 17.05 mW (°C cm2)−1 is achieved. Finally, a comparative Life Cycle Assessment with FR‐4 based electronics has been undertaken and the environmental impacts are calculated. The impact assessment shows a two magnitude lower impact on the environment for most categories, which suggests the approach is beneficial for the environment at a global production level. The results show that the photothermal pyrolysis of Kraft paper using a laser diode allows for low‐impact devices flexible and green electronics products.
