Albuquerque, N.M. — For the past three years a Sandia research team headed by Mat Celina has been investigating the performance of various piezoelectric polymer films that might one day serve as ultra ...

The tactile device is thin, flexible, and has 25 stimulation generating points within a 2 cm × 2 cm area. To achieve wearable, to install the driving circuit close to the device, we use high voltage ...

Piezoelectric crystals are a class of materials that exhibit a unique property called piezoelectricity. These crystals generate an electrical charge when subjected to mechanical stress or strain, and ...

Scientists develop a “best practice” protocol for researchers designing piezoelectric materials. This is the first of its kind in this advanced field of technology. An artistic impression of ...

(A) Schematic comparison of the puncture process with and without axial vibration, including 3 stages: pre-puncture (contact compression), puncture (membrane rupture), and post-puncture (insertion ...
