The most "smart" electronic medical record: can provide treatment guidance

"NighTIngale" is an electronic medical record application, and won the championship in the "White House Health Creative Challenge" hosted by the White House and Designer Fund. The application redefines the electronic medical record: making the treatment plan easier for patients to understand, showing them an intuitive interface, objective data display and convenient data export.

In addition to the electronic medical record function, "Nightingale" will also collect the patient's recent physical indicators and drug use, provide guidance for its next treatment, and can also set up email or phone prompts to remind patients to take medication on time. The application is now open source, making it easy for other medical service providers to use.

Designer Fund is a new angel fund dedicated to helping startups. It consists of Ben Blumenfeld with five years of Facebook designer experience and 500 Startups founder team member Enrique Allen (Enrique Allen) joint management.

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.
