“…In this case, the robot control algorithms can refer to these available indices in real-time and make the robots intervene when the exposure to risk is high. Furthermore, an index conceived in this way would also allow rapid administration of acoustic, visual, or vibrotactile feedback stimuli to workers to warn the workers that they are exposing themselves to a high risk [ 33 , 34 ]. For these reasons, there are also many experiences and activities [ 17 ] underway to include these new approaches within the International Standard Organization (ISO) 11,228 parts 1 and the technical report 12,295 [ 27 , 35 ].…”

When performing lifting tasks at work, the Lifting Index (LI) is widely used to prevent work-related low-back disorders, but it presents criticalities pertaining to measurement accuracy and precision. Wearable sensor networks, such as sensorized insoles and inertial measurement units, could improve biomechanical risk assessment by enabling the computation of an adaptive LI (aLI) that changes over time in relation to the actual method of carrying out lifting. This study aims to illustrate the concepts and mathematics underlying aLI computation and compare aLI calculations in real-time using wearable sensors and force platforms with the LI estimated with the standard method used by ergonomists and occupational health and safety technicians. To reach this aim, 10 participants performed six lifting tasks under two risk conditions. The results show us that the aLI value rapidly converges towards the reference value in all tasks, suggesting a promising use of adaptive algorithms and instrumental tools for biomechanical risk assessment.

“…These wearables represent an effective way to control worker centered occupational HRC technology. It has also been shown that these sensors can deliver auditory, visual, and haptic-vibrotactile stimuli ( 25 ) representing promising solutions to lower biomechanical effort and injuries related to the workplace.…”

“…In particular, we present Eco-Tac, an eco-friendly and ready-to-use haptic wearable device that provides vibrotactile feedback, incorporates biodegradable components, and is connected through degradable conductive tracks to a flexible photovoltaic module that provides solar-based power source to charge the battery of the device. Eco-Tac is inspired by our previous device ErgoTac, [59] which is also a wearable vibrotactile device that has been used in various applications in ergonomics, [60,61] assistance to people with disabilities, [62] or robot-human interaction. [63] We show that it is possible to use biobased and biodegradable materials as a component to make a flexible and stretchable biocomposite casing for the vibrotactile device, drastically reducing the amount of non-biodegradable plastic in the device.…”

Electronics and mechatronics waste is an exponentially increasing environmental issue, especially for wearable devices, due to their widespread diffusion into society and short life cycle. To promote their enormous benefits (e.g., in assisting visually impaired individuals) in a sustainable way, biobased and/or biodegradable organic materials should be used instead of traditional components. This manuscript presents a multidisciplinary approach, which bridges materials science and mechatronics, to propose the first ECO‐friendly wearable vibroTACtile device (Eco‐Tac). The design of Eco‐Tac includes integration on a cotton t‐shirt through a novel biodegradable conductive ink forming electrical tracks, a flexible commercially available solar panel, and the vibrotactile haptic device itself. The ink comprises a green solvent, anisole, a soft polybutylene adipate terephthalate biodegradable binder, and conductive nanocarbon materials. The device case is a biodegradable biocomposite. As such, the feasibility of using a sustainable energy source to supply power to the device and the possibility of using biodegradable materials in its manufacturing are demonstrated. An experiment with 20 blindfolded subjects is conducted, reporting the device's potential for assistance in manipulation tasks. Overall, the results of this work represent the first significant step toward the creation of wearable and sustainable haptic devices with green electronics and mechatronics approaches.
