Abstract: Apparatuses and methods, consistent with embodiments herein, are directed to an apparatus having a stretchable substrate and a plurality of nanostructures. While the plurality of nanostructures are adhered to the stretchable substrate, the stretchable substrate and the nanostructures are stretched and/or operate in a stretched mode in which the nanostructures are characterized by a resistance corresponding to a strain imparted due to the stretching. When the substrate is relaxed or the stretching otherwise lessened, the nanostructures continue to be characterized as a function of the strain and the corresponding resistance, with buckled segments of the nanostructures being adhered along a surface of the substrate.

Abstract: Flexible force/pressure sensors for producing electrical output signals proportional to forces or pressures exerted on the sensor include a thin, elastically deformable foam pad laminated between a pair of electrically conducive fabric sheets. A piezocapacitive embodiment of the sensor utilizes an elastically deformable perforated open-cell polyurethane foam pad preferably saturated with glycerin to increase the capacitance of the sensor. The piezocapacitive sensor section is preferably stacked onto a piezoresistive section having a second open-cell foam pad containing piezoresistive carbon particles to form a hybrid piezocapacitive/piezoresistive sensor. A third, “leaky dielectric” embodiment of a sensor includes a single open-cell foam pad which contains both a dielectric liquid and conductive particles. A low frequency such as d.c. to a few hertz is applied to a sensor to determine piezoresistive response of the sensor to forces or pressures and a higher frequency such as 30 KHz is applied to determine piezocapactive response.

Abstract: An electrode layer is formed on the upper surface of a first substrate, and a processing for partially removing the substrate is carried out in order to allow the substrate to have flexibility. To the lower surface of the first substrate, a second substrate is connected. Then, by cutting the second substrate, a working body and a pedestal are formed. On the other hand, a groove is formed on a third substrate. An electrode layer is formed on the bottom surface of the groove. The third substrate is connected to the first substrate so that both the electrodes face to each other with a predetermined spacing therebetween. Finally, the first, second and third substrates are cut off every respective unit regions to form independent sensors, respectively. When an acceleration is exerted on the working body, the first substrate bends. As a result, the distance between both the electrodes changes. Thus, an acceleration exerted is detected by changes in an electrostatic capacitance between both the electrodes.
