Summary: Piezoionic materials show potential as smart soft materials due to their similarity to biological systems in signal generation and transmission. A new study demonstrates the piezoelectric effect on an electrolyte-coated high-surface-area carbon nanotube yarn, allowing for the generation of large voltage gradients without an external bias. The yarn can be used in self-powered sensor gloves for hand gesture recognition and human-machine interactions.

Summary: Carbon nanotubes (CNTs) were successfully grown on custom-designed CMOS microheaters by a thermal chemical vapour deposition (CVD) process. A two-step reactive ion etching (RIE) method and design improvements were employed to achieve high selectivity, uniform etching, and a good etch rate. The CMOS-MEMS microheaters fabricated through this process were utilized for synthesizing CNTs by a local thermal CVD process.

Summary: The use of DLP printing technology with blading function allows for the fabrication of 3D anisotropic pressure and strain sensors by achieving nanoalignment of CNTs in each layer and facilitating good electrical communication between adjacent microlayers. The constructed 3D sensor displays high tensile and pressure responses, and the ability to detect pressure changes in all directions. The work offers a new way to create 3D anisotropic pressure/strain sensors for advanced flexible and stretchable sensing applications.
