摘要： An example system includes an input channel having a first end and a second end to receive particles through the first end, a sensor to categorize particles in the input channel into one of at least two categories, and at least two output channels. Each output channel is coupled to the second end of the input channel to receive particles from the input channel, and each output channel is associated with at least one category of the at least two categories. Each output channel has a corresponding pump operable, based on the categorization of a detected particle in a category associated with a different output channel, to selectively slow, stop, or reverse a flow of particles into the output channel from the input channel.

摘要： A piezoelectric cooling system and method for driving the cooling system are described. The piezoelectric cooling system includes a first piezoelectric cooling element and a second piezoelectric cooling element. The first piezoelectric cooling element is configured to direct a fluid toward a surface of a heat-generating structure. The second piezoelectric cooling element is configured to direct the fluid to an outlet area after heat has been transferred to the fluid by the heat-generating structure.

It is a multi functional multi-piezo material represented by the chemical formula Li(1−X)(1+a)NaXNbO3:MY (where M is at least one type of metal ion selected from transition metal ions), wherein the value of X is in the range from 0.10 or more to 0.98 or less, the value of Y is in the range from 0.0001 or more to 0.2 or less; and α is in the range from 0 or more. Such a multifunctional multi-piezo material has both high piezoelectric properties and high mechanoluminescence properties.

摘要： A piezoelectric haptic structure includes a thin film, a structural plate and a piezoelectric actuator. The thin film is stacked on the structural plate. The structural plate includes a plate body, a vibrating portion and an elastic portion. The plate body has an inner wall. The inner wall defines a space. The vibrating portion is located in the space and is away from the inner wall. The vibrating portion has an outer wall. The outer wall and the inner wall define a gap therebetween. The elastic portion is elastically connected between the outer wall and the inner wall. The elastic portion seals the gap. The piezoelectric actuator is sandwiched between the thin film and the vibrating portion.
