The manufacturing of sensors through 3D printing combines speed, design freedom, and the possibility of using waste as a substrate. In the circular economy model, various results have been achieved, and typically discarded residues are used as low-cost resources. A research team in Brazil has proposed a highly creative solution that involves printing electrochemical sensors on fallen leaves. The t...
Applications are now open for the 2026 SPIE Startup Challenge. The annual entrepreneurial pitch competition is held by SPIE, the international society for optics and photonics, as part of SPIE Photonics West.In 2026, Photonics West will be held 17-22 January in San Francisco’s Moscone Center, with the SPIE Startup Challenge finals being held 20 January.The SPIE Startup Challenge is a competitive e...
The femtosecond laser emits ultra short optical pulses with a duration of less than one picosecond, reaching the femtosecond level (1fs=10-15s). The characteristics of femtosecond laser are extremely short pulse width and high peak intensity.Ultra short pulse trains can minimize residual heat, ensure precise material processing, and minimize incidental damage. Its high peak intensity can induce no...
Zhao Yun/Columbia Engineering Company provided an advanced schematic of a photonic integrated chip, which aims to convert high-frequency signals into low-frequency signals using all optical frequency division.Scientists have built a small all optical device with the lowest microwave noise ever recorded on integrated chips.In order to improve the performance of electronic devices used for global n...
Recently, Amada weld tech Inc., a Japanese supplier of welding and cutting solutions, grandly launched a new wl-300a precision laser welding workstation, which is equipped with advanced continuous wave (CW) or quasi continuous wave (QCW) fiber lasers. It has a wide range of applications, especially for metal welding and processing of selected plastic materials, especially in the aerospace field.Wl...
