TL;DR: The ZnO nanoparticle-PVDF composite thin film was demonstrated as a flexible wearable motion sensor, where different hand gestures were detected by the device with distinctive output voltage amplitudes and patterns and it was demonstrated that the energy harvested from finger tapping at ~2 Hz can charge a capacitor with a large output power density.

TL;DR: The role of micro-/nanoparticles of various physicochemical properties plays significant roles in biomedical engineering from biosensing, in vivo imaging, in vitro diagnosis, drug delivery to therapy as mentioned in this paper.

TL;DR: A facile and straightforward flow synthesis strategy to control zinc oxide (ZnO) of different shapes on a few seconds time scale, based on the 1.5-run spiral-shaped microfluidic reactor, and the structure-dependent efficacy is observed, where higher surface area ZnO structures generally behave better performance.

TL;DR: Using a miniaturized multi-run spiral-shaped microreactor, a flow synthesis strategy is developed to continuously produce hollow spherical silica with hierarchical sponge-like pore sizes ranging from several nanometers to over one hundred nanometers, promising in the fields of separation and purification, bioimaging, catalysis, and theranostics.

TL;DR: A cardiac energy harvesting strategy is reported, which is integrated into part of the existing pacemaker lead and otherwise with no direct contact of heart, by utilizing porous piezoelectric thin films in a bioinspired self-wrapping helical configuration for flexible integration with existing implantable medical devices.
