“…Studies have shown that the two most essential sensory information proposed by amputees are force and position ( Hermens et al, 2011 ). The Vib-FB has been used to provide grasp perception in many existing studies ( Li et al, 2016 ; Yamada et al, 2016 ; Markovic et al, 2018 ; Niwa et al, 2021 ; Johnson et al, 2022 ). Vib-FB has been used in the virtual elbow angular position control ( Wheeler et al, 2010 ; Hasson and Manczurowsky, 2015 ) and virtual wrist angular position control ( Bark et al, 2010 ; Bensmaia et al, 2015 ).…”

Wearing a myoelectric prosthesis is a basic way for limb amputees to restore their lost limb functions in the activities of daily living (ADLs). However, it is estimated that around 40% of amputees refuse the prosthesis. One of the primary reasons would be that the current prostheses lack appropriate sensory feedback. Currently, the amputees only depend on their visual feedback (Vis-FB) when using their arm prostheses. It would be difficult for them to accurately control the wrist position, which is vital for flexible manipulation in ADLs. This manuscript designed a myoelectric arm prosthesis with wrist position feedback (WP-FB). To study the effect level of position feedback on prosthetic control, two tests were performed. The vibrotactile perception range test aims to analyze the perception sensitivity of the vibration in humans and obtain the optimal perception range utilized in the sensory feedback test. The sensory feedback test analyzes the effectiveness of the position feedback by comparing three feedback methods of Vis-FB, WP-FB, and a combination of Vis-FB and WP-FB (VP-FB). These tests were conducted by asking six able-bodied subjects to perform 20 movement combinations of five target positions. The WP-FB was transiently activated with five vibrating motors embedded in an armband to stimulate the arm stump when the prosthetic wrist rotates to the target positions. Our experimental results showed that when WP-FB was added to the prosthetic control, the absolute angular error (AAE) of the prosthetic wrist declined from 4.50° to 1.08° while the success rate 3 (SR3) increased from 0.34 to 0.84, respectively. This study demonstrates the importance of WP-FB to the effective control of the arm prosthesis.

Recent developments in the fields of materials science and engineering technology (mechanical, electrical, biomedical) lay the foundation to design flexible bioelectronics with dynamic interfaces, widely used in biomedical/clinical monitoring, stimulation, and characterization. Examples of this technology include body motion and physiological signal monitoring through soft wearable devices, mechanical characterization of biological tissues, skin stimulation using dynamic actuators, and energy harvesting in biomedical implants. Typically, these bioelectronic systems feature thin form factors for enhanced flexibility and soft elastomeric encapsulations that provide skin-compliant mechanics for seamless integration with biological tissues. This review examines the rapid and continuous progress of bioelectronics in the context of design strategies including materials, mechanics, and structure to achieve high performance dynamic interfaces in biomedicine. It concludes with a concise summary and insights into the ongoing opportunities and challenges facing developments of bioelectronics with dynamic interfaces for future applications.
