Design of a Simple and Rugged Soft Polydimethylsiloxane‐Carbon Nanotube‐Graphene‐Based Composite Sensor

Advanced Materials Technologies, EarlyView.
This research presents an easy to fabricate, low‐cost, flexible piezoresistive deformation sensor comprised of a carbon nanotube, few‐layer graphene, and polydimethylsiloxane composite. The sensor detects deformations and vibrations up to 600 Hz with 0.1% strain sensitivity from stiff and soft targets in dry and wet environments.

Predicting and measuring fluid responsiveness with echocardiography

Echo Research and Practice, 2016
Echocardiography is ideally suited to guide fluid resuscitation in critically ill patients. It can be used to assess fluid responsiveness by looking at the left ventricle, aortic outflow, inferior vena cava and right ventricle.
