Holistically, after the green revolution, India has been a global agricultural powerhouse of various crops and in present most of the farmers adopt the traditional irrigation methods but challenging task is in utilizing minimum water resource for more productivity per crop in diversified Indian environmental conditions. Water is a precious & scarce resource in many areas of the country due to traditional agricultural irrigation & industrial use. Hence, to limit water loss & wastage in farming it is important for maximum water application efficiency. Indeed, Systematic Irrigation System (SIS) for farming is need of hour and hence, attempt is made for development of SIS using computational device, and NodeMCU & Sensor technology are illustrated in this article. The SIS prototype has developed deploying ESP8266 Wi-Fi SoC development board and various sensors such as humidity, temperature, soil moisture, PIR & rain sensor. Graphic User Interface is developed in Blynk platform. This prototype has been tested in the laboratory successfully for application efficiency and has found good performance as expected.
It is challenging to detect knee injuries precisely. Many criteria include edema, patient guarding, physician experience, and the manual evaluation degree of the wound. These elements may contribute to an inadequate or incorrect diagnosis, which may lead to poor care and healing. Athletes frequently sustain knee injuries, which can happen during daily activities and frequently result in tears to one or more of the four ligaments. A doctor performs several routine tests while manually manipulating the knee for assessment. Despite being regarded as best practices, these manual tests are known to have some errors, with up to 1 in 8 patients receiving the incorrect diagnosis as a result of testing flaws. Where available, MRI imaging is used to confirm the diagnosis; however, due to time and financial constraints, this is not the case for all individuals. Creating and testing a wearable diagnostic system housed in a knee sleeve was the aim of this research. To derive quantitative measurements toward a diagnosis, integrated sensors were utilized to track movement and electromyographic activity. A replica of the lower leg and knee that had been manufactured was used to test the movement and displacement monitoring subsystems. According to preliminary findings, the range of motion tests produced reliable readings with an average percentage error of 1%, while the laxity test produced values with an average percent error of 3% (0.1 to 0.2 mm). A doctor could utilize the measurement produced by this technology to inform their decision-making.
This paper presents EXOTIC, a revolutionary assistive upper-limb exoskeleton that offers previously unheard-of levels of control and versatility to people with total functional tetraplegia. While the context in which these exoskeletons should work is less or not prioritized despite posing significant technical needs, the exoskeleton literature in publication mostly concentrates on the fundamental technical components of exoskeleton design and control, ranging from fundamental technical features to practical real-world applications. The EXOTIC includes a lightweight, safe, wheelchair-mountable, and simple-to-put-on-and-take-off exoskeleton that can assist individuals with tetraplegia in multiple highly desired activities of daily living, a semi-automated computer vision guidance system that the user can activate when appropriate, and a tongue control interface that enables complete, conscious, and ongoing control over every movement the exoskeleton is capable of. Ten healthy participants and three users suffering from tetraplegia due to a spinal cord injury participated in the EXOTIC testing. Throughout the trials, EXOTIC was able to help individuals with total functional tetraplegia and ventilator dependency execute tasks like drinking and getting snacks. The utility of the EXOTIC was attested to by the users.
The treatment of low back pain usually includes exercise, analgesics, prostheses, and, in severe cases, surgery. Early treatments based on postural control are essential to prevent low back pain and mitigate permanent damage. This paper presents a wearable device with an estimated cost below $100 that uses inertial units with triaxial accelerometers, gyroscopes, and magnetometers to measure the orientation of three sections of the spine. The device integrates the absolute and relative orientations from the sensors to estimate the posture of the back in real-time and uses a fuzzy system to control a vibration unit that indicates to the user when to correct the posture of the back. This paper validated the device in controlled conditions, obtaining an rms deviation ≤1.24, and conducted a preliminary clinical pilot study with patients afflicted by lumbar hyperlordosis. This paper observed improved postural control and a reduction of low back pain in all cases. These results show the device's promising potential to reduce pain, improve postural therapies, and raise postural awareness in patients with low back pain.
A major issue in the medical field worldwide is the limited number of organ donors available for transplants. The conventional methods are constrained by issues like scarcity of donors, further harm, and limited resources. The 3D printing technology provides a hopeful remedy by allowing the quick creation of customized tissue scaffolds, fixing tissue defects with cells, and potentially printing organs and tissues. These customized implants blend with the patient's tissue and include specific material patterns and cell clusters to promote cell growth and maturation, aiding in tissue repair. This review examines the existing obstacles and progress in 3D printing for medical purposes, specifically focusing on materials and extracellular matrix fabrication, showcasing different types of biomedical materials and recent innovations.
