In-Vivo Study of Passive Musculotendon Mechanics in Chronic Hemispheric Stroke Survivors
We characterized the passive mechanical properties of the affected and contralateral musculotendon units in 9 chronic stroke survivors as well as in 6 neurologically-intact controls. Using a position-controlled motor, we precisely indented the distal tendon of the biceps brachii to... Read more

Performance Evaluation of a Wearable Tattoo Electrode Suitable for High-Resolution Surface Electromyogram Recording
Commercial high-density surface electromyography (HDsEMG) electrodes have limited spatial fidelity, and require electrode paste. As a result, the recorded signals have limited sharpness, inadequate spatial density, and are prone to movement artifacts during muscle contraction. We here demonstrate a novel TATTOO electrode, a dry HDsEMG electrode with a programmable layout. The tattoo electrode is built on stretchable electronics and offers superior skin conformity that can guarantee recording of high-quality HDsEMG signal. We routinely record a larger signal amplitude with higher signal power and occupied bandwidth compared to commercial electrodes. This will potentially enable high-quality recording in clinical applications... Read more
