fabricated a nanowire-channel intrinsically stretchable neuromorphic
transistor (NISNT) that perceives both tactile and visual information
and emulates neuromorphic processing capabilities. The device demonstrated
excellent stretching endurance of 1000 stretch cycles while retaining
stable electrical properties. The device was then applied as a multisensitive
afferent nerve that processes information in parallel. Compatible
with skin deformation, the devices are attached to fingers to serve
as conformal strain sensors and neuromorphic information-processing
units for gesture recognition. The excitatory postsynaptic current
in each device represents shape changes and is then analyzed using
softmax activation processing of the neural network to recognize gestures.
A multistage neural network that uses NISNT was used to further confirm
the gestures. This work demonstrated an idea toward multisensory artificial
nerves and neuromorphic systems.
