A self-powered triboelectric nanosensor for detecting the corrosion state of magnesium treated by micro-arc oxidation

A self-powered triboelectric nanosensor for mercury ion detection.

Mercury is a highly toxic metal that can pose serious dangers to the environment and human health. Therefore, monitoring the mercury concentration is an extremely important issue to prevent such a toxic metal from endangering human life. Hg ions are by far the most stable inorganic form of mercury, which are non-biodegradable and bioaccumulable. Even at a very low concentrations, they can still...

Improved biological performance of magnesium by micro-arc oxidation

Magnesium and its alloys have recently been used in the development of lightweight, biodegradable implant materials. However, the corrosion properties of magnesium limit its clinical application. The purpose of this study was to comprehensively evaluate the degradation behavior and biomechanical properties of magnesium materials treated with micro-arc oxidation (MAO), which is a new promising s...

Triboelectric nanogenerator as self-powered active sensors for detecting liquid/gaseous water/ethanol

Triboelectric nanogenerator built inside clothes for self-powered glucose biosensors

[email protected] ntributed equally Abstract A triboelectric nanogenerator (TENG) based on the contact-separation mode between a patterned polydimethylsiloxane (PDMS) film and an Al foil was fabricated between clothes for harvesting body motion energy. Under the generally walking, the maximum output of voltage and current density are up to 17 V and 0.02 μA/cm, respectively. The TENG with a singl...
