Paper/Carbon Nanotube-Based Wearable Pressure Sensor for Physiological Signal Acquisition and Soft Robotic Skin
A wearable and flexible
pressure sensor is essential to the realization of personalized medicine
through continuously monitoring an individual’s state of health
and also the development of a highly intelligent robot. A flexible,
wearable pressure sensor is fabricated based on novel single-wall
carbon nanotube /tissue paper through a low-cost and scalable approach.
The flexible, wearable sensor showed superior performance with concurrence
of several merits, including high sensitivity for a broad pressure
range and an ultralow energy consumption level of 10<sup>–6</sup> W. Benefited from the excellent performance and the ultraconformal
contact of the sensor with an uneven surface, vital human physiological
signals (such as radial arterial pulse and muscle activity at various
positions) can be monitored in real time and in situ. In addition,
the pressure sensors could also be integrated onto robots as the artificial
skin that could sense the force/pressure and also the distribution
of force/pressure on the artificial skin
Electrospinning-Derived “Hairy Seaweed” and Its Photoelectrochemical Properties
Highly porous three-dimensional (3D)
hierarchical nanostructures
suspended in aqueous media were facilely prepared via electrospinning
of polyacrylonitrile (PAN)/indium tin oxide (ITO) nanofibers and collection
of the hybrid nanofibers by water, followed by hydrothermally growing
ZnO nanorods from the nanofibers. The large interfiber distances facilitated
the uniform growth of the ZnO nanorods throughout the whole system.
The suspended PAN/ITO nanofibers process excellent light trapping
capability due to their centimeter-sized dimensions and hence large
light penetration path. This significantly increases the probability
of multiple-reflections, leading to high absorption with almost zero
transmission when the size of the sample reaches 10 mm in the direction
parallel to incident light. High photocurrent was generated when the
nanorods-on-nanofibers was used as a photoanode. The high photocurrent
density generated by the anode can be attributed to its excellent
light-trapping capability brought by the large amount of interaction
sites between the ZnO nanorods and light, its large contact area with
electrolyte, as well as the conduction path constructed by high-content
ITO nanoparticles
