Simultaneously stretchable and compressible flexible
strain sensors
are highly desired in many advanced applications including the wearable
field. However, the fabrication of such dual-function sensors with
a wide sensing range is still challenging. In this work, a simultaneously
stretchable and compressible foam strain sensor was fabricated by
skillfully introducing oriented pores into the highly stretchable
elastic composite based on carbon nanotubes and poly(styrene-b-ethylene–butylene-b-styrene) (SEBS)
by a freeze-drying method, in which cyclohexane was employed as the
freeze-drying solvent. The high stretchability of SEBS and the abundant
compressible space imparted by the pores endowed the resultant flexible
foam sensor with highly stretchable (250%) and compressive (−50%)
characteristics simultaneously. Thanks to the outstanding flexible
features, the foam sensor enabled simultaneous monitoring of multiple
human movements, such as bidirectional wrist bending, knee bending,
foot stepping, and so forth. The foam sensor could encrypt human gesture
signals into electrical signals and transmit them to the machine to
realize the human–computer interaction, which could greatly
broaden the application prospect of flexible strain sensors in the
field of intelligent sensing.
Purpose: Breast cancer (BC) is the most common malignant tumor in women. Due to the mechanism of BC has not yet been completely clear, we aim to identify the key pathway and genes in BC based on bioinformatics method.Methods: Samples were obtained from NCBI-GEO website. Then, GEO2R tools and Venn diagram software were used to identify the differentially expressed genes (DEGs). Next, analyze Kyoto
