Mechanically driven luminescence in a ZnS:Cu-PDMS composite

open access: yesAPL Materials, 2016
The conventional mechanoluminescence (ML) mechanism of phosphors such as SrAl2O4:Eu and ZnS:Mn is known to utilize carrier trapping at shallow traps followed by stress (or strain)-induced detrapping, which leads to activator recombination in association ...

Origin of mechanoluminescence from Mn-activated ZnAl 2 O 4 : Triboelectricity-induced electroluminescence

open access: yes, 2015
Luminescence induced by friction, mechanoluminescence (ML) has been observed for ZnAl2O4: Mn2+ (ZAO:Mn) fabricated by systematically controlling the reducing temperature. The reducing treatment produced lattice defects under a reducing atmosphere.

Distributed Micropneumatic Sensors for Soft Robots to Detect Touch and Pose

open access: yesAdvanced Robotics Research, EarlyView.
Soft robots need integrated touch and pose sensing for safe and reliable operation. This work presents a three‐fingered soft gripper with 18 micropneumatic sensors made from the same materials as its pneumatic actuators. By measuring airflow resistance changes in deforming microchannels of the sensors, finger pose and contact are detected, enabling ...
