A structural extension was developed to facilitate sensor integration and to enable the application of different buckling boundary conditions. Results show that the clamped–clamped configuration generated at least 1.65 times higher output voltage, and three times greater peak strain compared to other boundary conditions. An experimentally validated analytical model was employed to assess and improve the performance of buckled piezoelectric sensors in dynamic environments. The findings highlight that introducing initial buckling reduces signal perturbations, enhances voltage linearity across loading frequencies, and extends the effective strain measurement range.

The tumor spheroid is cultured in a gas-impermeable plastic chamber, which effectively simulates the limited oxygen supply environment of solid tumors, thereby providing a realistic platform for studying tumor behavior and interactions with surrounding cells. To characterize the three-dimensional spatial oxygen tension profiles, we utilized oxygen-sensing microbeads with widefield frequency-domain fluorescence lifetime imaging microscopy (FD-FLIM). The FD-FLIM setup ensures minimal excitation light dosage to reduce photocytotoxicity while providing capabilities for reliable three-dimensional oxygen tension measurements for an extended period. The experimental results show that the oxygen tensions were lowered to approximately 6% in the neighborhood of a colon cancer cell line (HCT116) tumor spheroid. Interestingly, when the tumor spheroid is co-cultured with a monolayer of endothelial cells (human umbilical vein endothelial cell, HUVEC), the lowering of oxygen tension can be alleviated. Our findings highlight the significant interactions between the tumor spheroid and endothelial cells, emphasizing the crucial role of the endothelium in regulating oxygen microenvironments and influencing angiogenesis. Furthermore, the model provides a valuable tool for exploring the dynamics of tumor biology.
