“…However, both of these are relatively expensive materials so they point towards the possibility to use a separate sterile microfluidic component, such as a capillary, to reduce the cost of disposal and replacement for each biological sample [30]. It is also possible to integrate piezoelectric materials in thick [53] or thin film [54,55] form, or indeed bonded bulk material [56], with other components. Requiring an additional level of fabrication sophistication, typically including photolithography [57], this approach may be very useful when the number of devices is high and may be a key issue in differentiating acoustic manipulation from optical manipulation [58], where integration is still much harder.…”

Ultrasonic fields are able to exert forces on cells and other micron-scale particles, including microbubbles. The technology is compatible with existing lab-on-chip techniques and is complementary to many alternative manipulation approaches due to its ability to handle many cells simultaneously over extended length scales. This paper provides an overview of the physical principles underlying ultrasonic manipulation, discusses the biological effects relevant to its use with cells, and describes emerging applications that are of interest in the field of drug development and delivery on-chip.

“…Although much research has been conducted on printed electronics, there has been relatively little work on printed mechanical actuators [18][19][20][21][22][23][24][25][26] . EAPs are a promising class of materials for such printed components because they can be solution processed [27][28][29] .…”

Printed unmanned aerial vehicles using paper-based electroactive polymer actuators and organic ion gel transistors

We combined lightweight and mechanically flexible printed transistors and actuators with a paper unmanned aerial vehicle (UAV) glider prototype to demonstrate electrically controlled glide path modification in a lightweight, disposable UAV system. The integration of lightweight and mechanically flexible electronics that is offered by printed electronics is uniquely attractive in this regard because it enables flight control in an inexpensive, disposable, and easily integrated system. Here, we demonstrate electroactive polymer (EAP) actuators that are directly printed into paper that act as steering elements for low cost, lightweight paper UAVs. We drive these actuators by using ion gel-gated organic thin film transistors (OTFTs) that are ideally suited as drive transistors for these actuators in terms of drive current and frequency requirements. By using a printing-based fabrication process on a paper glider, we are able to deliver an attractive path to the realization of inexpensive UAVs for ubiquitous sensing and monitoring flight applications.

Study on improving current generating time of piezoelectric energy harvesting system

This study combined a ceramic, metal alloy, and polymer in a piezoelectric energy harvesting system. The proper container film for curing the urethane rubber was determined to be a Si-coated polyester film. Furthermore, a technique was developed to embed a piezoelectric energy system in urethane rubber (soft and hard); the resulting effects on the output voltage generation of this system were experimentally determined. Comparing the uncoated and hard urethane rubber-coated systems, the latter system improved the energy generation time by a factor of 50 by restricting the recovery time of the metal alloy and storing applied mechanical energy in urethane rubber, providing more time for the piezoelectric ceramic to generate output current. From the LED lighting test results, the urethane rubber coating increased the usable voltage generating time from 0.05 s to 2.5 s. The improved generating time is useful for piezoelectric energy harvesting systems with irregular ambient energy sources.
