The primary objective of this research is to develop a model-based framework for the indentation on the surface of a soft electronic skin. In the current paper, the model has been applied to a soft electronic skin embedding piezoelectric polymer (PVDF, polyvinylidene fluoride) transducers. We revisit in a dimensionless fashion an analytical...

Materials integrated tactile sensing systems are still far from relying on well assessed and mature technological approaches even if research efforts date back to the late 80's. This is mainly due to the fact that a killing application has not yet been identified even if in the last years promising applications have come to the stage, e.g....

This paper proposes a validation method of the fabrication technology of a screen‐printed electronic skin based on polyvinylidene fluoride‐trifluoroethylene P(VDF‐TrFE) piezoelectric polymer sensors. This required researchers to insure, through non‐direct sensor characterization, that printed sensors were working as expected. For that, we...

Stroke patients suffer from impairments of both motor and somatosensory functions. The functional recovery of upper extremities is one of the primary goals of rehabilitation programs. Additional somatosensory deficits limit sensorimotor function and significantly affect its recovery after the neuromotor injury. Sensory substitution systems,...

The lack of tactile sensation in current upper limb prostheses is the key limitation to enable more intuitive use of the prosthesis and restore the functionality of the natural limb. Electronic skin in the form of tactile sensing arrays can be integrated onto the upper limb prosthetic device to record information about touch, given back to the...

Modern prostheses aim at restoring the functional and aesthetic characteristics of the lost limb. To foster prosthesis embodiment and functionality, it is necessary to re-establish both volitional control and sensory feedback. Contemporary feedback interfaces presented in research use few sensors and stimulation units to feedback at most two...

Closing the prosthesis control loop by providing tactile sensory feedback to the user is a key point in research on active prosthetics as well as an often cited requirement of the prosthesis users. © 2018 IEEE.

Computation accuracy can be adequately tuned on the specific application requirements in order to reduce power consumption. To give some examples, image processing and audio/speech recognition e.g., multimedia applications may provide more accurate outputs than human capabilities can appreciate. In this case, producing inexact numerical outputs...

Reconstructing the sense of touch in prosthetics is a long-standing research challenge. To this aim, the prosthesis can be supplied with sensory arrays to measure the tactile interaction with the environment. In addition, a reliable feedback system is required to code and transmit the measured somatosensory information to the residual limb....
