“…Stimulating gloves (Meers and Ward, 2005), headbands (Kajimoto et al, 2006), vests (Jones et al, 2006;Cancar et al, 2013), and belts (Van Erp et al, 2005) have also been explored for navigational, kinesthetic and vision reproduction purposes. The developments of methods such as electronic skin (Fu et al, 2018) will open new frontiers in tactile-based sensory substitution devices.…”

“…[49] On the brain level, Fu et al and Dai et al further demonstrated direct TENG stimulation on rat's somatosensory cortex and motor cortex. [50,51] The TENGs work as ion pumps when energy conversion is achieved by coupling between the triboelectric effect and the electrostatic effect, and TENGs can be potentially developed into fully implantable electrical muscle stimulation systems to replace the currently available wearable TENG solution as demonstrated in the previous peripheral nerve and brain stimulation works, and such TENGs can simultaneously serve as waveform generator and power supply to provide therapeutic interventions to the muscles through implanted electrodes (Figure 1).…”

Muscle function loss is characterized as abnormal or completely lost muscle capabilities, and it can result from neurological disorders or nerve injuries. The currently available clinical treatment is to electrically stimulate the diseased muscles. Here, a self‐powered system of a stacked‐layer triboelectric nanogenerator (TENG) and a multiple‐channel epimysial electrode to directly stimulate muscles is demonstrated. Then, the two challenges regarding direct TENG muscle stimulation are further investigated. For the first challenge of improving low‐current TENG stimulation efficiency, it is found that the optimum stimulation efficiency can be achieved by conducting a systematic mapping with a multiple‐channel epimysial electrode. The second challenge is TENG stimulation stability. It is found that the force output generated by TENGs is more stable than using the conventional square wave stimulation and enveloped high frequency stimulation. With modelling and in vivo measurements, it is confirmed that the two factors that account for the stable stimulation using TENGs are the long pulse duration and low current amplitude. The current waveform of TENGs can effectively avoid synchronous motoneuron recruitment at the two stimulation electrodes to reduce force fluctuation. Here, after investigating these two challenges, it is believed that TENG direct muscle stimulation could be used for rehabilitative and therapeutic purpose of muscle function loss treatment.

A new self-powered brain-linked vision electronic-skin (e-skin) for mimicking retina is realized from Polypyrrole/Polydimethysiloxane (Ppy/PDMS) triboelectric-photodetecting pixel-addressable matrix. The e-skin can be driven by human motion, so no external electricity power is needed in both photodetecting and signal transmitting processes. The triboelectric output is significantly dependent on the photo illumination, which can act as visual bionic electric impulse. Taking blue illumination (405 nm) as an example, as the e-skin is exposed to 100 µW cm −2 illumination, the output current decreases from 7.5 to 4.9 nA, and the photosensitivity is 34.7. And the photosensitivity of the e-skin keeps stable with different bending angles and force. The e-skin is flexible enough to combine with human body and can be driven by blinking eyes to detect UV illumination. In addition, the 4 × 4 photodetecting unit matrix in the e-skin can map singlepoint and multipoint illumination-stimuli (visual-image recognition) via the multichannel data acquisition method. Furthermore, the e-skin can directly transmit photo detecting signals into mouse brain for participating in the perception and behavior intervention. This new self-powered perception device can lower down the production cost of traditional complex sensory-substitution system, and can be easily extended to various brain-machine interaction applications.
