    摘要： An energy harvesting device and a method of using the energy harvesting device to generate an electrical charge are described. The energy harvesting device comprises a mass and at least two tethers, at least one of which comprises a piezoelectric material that is mechanically stressable upon deflection of the at least two tethers. Each of the tethers comprises a first end coupled to the mass and a second end coupled to a reference structure, and the tethers are arranged about the mass such that the mass is moveable within a straightline path relative to the reference. The movement of the mass causes the deflection of the tethers, resulting in the generation of an electric charge. The device is preferably operable at the microscale.

    摘要： Disclosed are systems, devices, methods, and other implementations, including a device to detect at least one target species in a sample, with the device including a microfluidic channel configured to receive the sample containing the at least one target species and a biocompatible ferrofluid in which the at least one target species is suspended, a detector to determine the at least one target species in the sample, and at least two of electrodes positioned proximate the microfluidic channel, the at least two electrodes configured to generate controllable magnetic forces in the sample containing the ferrofluid when a controllable at least one electrical current is applied to the at least two electrodes. The generated controllable magnetic forces causes the at least one target species to be directed towards the detector. Also disclosed are devices for separating target species in a ferrofluid, and for focusing target species suspended in a ferrofluid.

    摘要： An energy harvesting device (FIG. 1) and a method of using the energy harvesting device to generate an electrical charge are described. The energy harvesting device comprises a mass (2) and at least two tethers (4, 6, S and 10), at least one of which comprises a piezoelectric material that is mechanically stressable upon deflection of the at least two tethers. Each of the tethers comprises a first end (12) coupled to the mass (2) and a second end (14) copied to a reference structure (16), and the tethers are arranged about the mass such that the mass is moveable within a straight line path relative to the reference. The movement of the mass causes the deflection of the tethers, resulting in the generation of an electric charge. The device is preferably operable at the microscale.
