【Recent Advances in Wearable Electromechanical Sensors Based on Auxetic Textiles】 Advanced Functional Materials (IF 18.5) Pub Date : 2024-09-03 , DOI:10.1002/adfm.202409242 Textile-based electromechanical sensors are increasingly used as wearable sensors for various applications, such as health monitoring and human-machine interfaces. These sensors are becoming increasingly popular as they offer a comfortable and conformable sensing platform and possess properties that can be tuned by selecting different fiber materials, yarn-spinning techniques, or fabric fabrication methods. Although it is still in its early stages, recent attempts have been made to introduce auxeticity to textile sensors to enhance their sensitivity. Having a negative Poisson's ratio, i.e., undergoing expansion laterally when subjected to tensile forces and contraction laterally under compressive forces, makes them distinct from conventional sensors with positive Poisson's ratio. This unique feature has demonstrated great potential in enhancing the performance of electromechanical sensors. This review presents an overview of electromechanical sensors based on auxetic textiles (textiles made from auxetic materials and/or non-auxetic materials but with auxetic structures), specifically focusing on how the unique auxetic deformation impacts sensing performance. Sensors based on different working mechanisms, including piezoelectric, triboelectric, piezoresistive, and piezocapacitive, are covered. It is envisioned that incorporating auxeticity and electromechanical sensing capabilities into textiles will significantly advance wearable technology, leading to new sensors for health monitoring, fitness tracking, and smart clothing.  https://lnkd.in/eY2_E-cn

Igus products in a wearable technology exoskeleton The exoskeleton is designed to make repetitive arm movements easier and less strenuous for employees, and is lightweight and compact. The igus products used in the exoskeleton are iglidur bearings, which are non-corrosive and do not require lubrication, making them ideal for use in challenging environmental conditions. The iglidur bearings are used in the rotating mechanisms of the exoskeleton, which need to be easily rotatable under heavy axial loads. The bearings are cylindrical plain bearings with and without flange and thrust washers, which guarantee a gradual activation during each movement of the arm. The use of igus products in the exoskeleton has several benefits, including: * Lightweight and compact design * Non-corrosive materials * No need for lubrication * Easy rotation under heavy axial loads Overall, the use of igus products in the exoskeleton helps to create a comfortable and effective wearable technology that can be used for extended periods of time.

Human Powered Batteries. Researchers create a stretchy “biological battery” Researchers at Colorado University (CU) Boulder have developed a new, low-cost wearable device that "transforms the human body into a biological battery." The device is stretchy enough that it can be worn like a ring, a bracelet or any accessory that touches the skin. The device taps into a person’s natural heat, employing thermoelectric generators to convert the body’s internal temperature into electricity. “In the future, we want to be able to power your wearable electronics without having to include a battery,” said Jianliang Xiao, senior author of the paper and an associate professor in the Paul M. Rady Dept. of Mechanical Engineering. The device can generate about 1 volt of energy for every square centimeter of skin space. This is less voltage per area than most existing batteries can provide, but it is enough to power small wearable electronics, such as a watch or fitness tracker. What makes this device different from previously developed thermoelectric wearable devices, is that it’s stretchy, can heal itself when damaged and is fully recyclable. Power can be boosted by adding in more blocks of generators, similar to building with Lego toys. The researchers have calculated that a person taking a brisk walk could use a device the size of a typical sports wristband to generate about 5 volts of electricity, which is more than the power in many watch batteries. The new devices are also as resilient as biological tissue. If your device tears, for example, you can pinch together the broken ends, and they’ll seal back up in just a few minutes. And when you’re done with the device, you can dunk it into a special solution that will separate out the electronic components and dissolve the polyimine base, so that each of the ingredients can be reused. Coauthors on the new paper include researchers from China’s Harbin Institute of Technology, Southeast University, Zhejiang University, Tongji University and Huazhong University of Science and Technology.
