Whether you use a traditional flat iron or a steamer, it's very troublesome. The laundry is expensive. Is there any smarter ironing equipment?

Take a look at this Dressy2Go, I call it "solid iron". Just hang your clothes on it, spray some water and turn on the switch, then adjust the power and temperature, and your clothes will be flattened in about a few minutes.

Maybe you will think of Dress2Go as a device that resembles a hot air fan, but there are still some differences. It uses a new type of PTC technology that uses ceramics, chips, and rubber instead of electric heating wires, making it safer and capable of achieving up to 1500W of heat.

In addition, Dress2Go also has built-in overheating and overturn protection to prevent fires.

In order to apply to more kinds of clothes, Dress2Go also includes two support sleeves that can be applied to short T-shirts and shirts, short skirts, etc., and the other is applicable to pants and shorts, basically all clothes can be used .

Currently, Dressel2Go is crowdfunding on the kickstarter with an early support price of US$239 (approximately RMB1,593) and is expected to start shipping in May 2017.

Lead Free Piezoelectric Elements

The Co-Al Co-doped Barium Titanate Lead-free Piezoelectric Ceramics was successfully developed by Yuhai company through repeated experiments. By Researching the influence of Co-Al Co-doping on the structure and properties of Barium Titanate-based piezoelectric ceramics, the formulation and preparation technology of Barium Titanate-based piezoelectric ceramics were optimized. Yuhai`s BaTiO3 was prepared by conventional solid-phase sintering method, with the piezoelectric constant d33 (>170pC/N), dielectric loss tgδ≤0.5% and mechanical coupling coefficient Kp≥0.34.

Barium titanate lead-free piezoelectric ceramics are important basic materials for the development of modern science and technology, which was widely used in the manufacture of ultrasonic transducers, underwater acoustic transducers, electroacoustic transducers, ceramic filters, ceramic transformers, ceramic frequency discriminators, high voltage generators, infrared detectors, surface acoustic wave devices, electro-optic devices, ignition and detonation devices, and piezoelectric gyroscope and so on.

Application: military, ocean, fishery, scientific research, mine detection, daily life and other fields.
