Hydrogel‐Based 3D‐Printable Stretchable Pressure Sensor

Advanced Materials Technologies, EarlyView.
We present a carbon‐black‐functionalized double‐network granular hydrogel (DNGH) pressure sensor capable of detecting pressures from 200 Pa, equivalent to a light finger touch, up to 500 kPa. The sensor exhibits signal drifts below 3.5% after 800 cycles and response times around 80 ms. Leveraging this broad sensing range, we 3D print this material into

Evaluation of uncertainty connected with Transient thermal-Hydraulics Calculations

, 2014
Three approaches for the evaluation of uncertainty expected in calculations performed by system thermal-hydraulic codes are discussed : a) The statistical approach initially proposed by United States Nuclear Regulatory Commission, later on made robust by GRS (Geselschaft fur Reaktosicherhet) in Germany with the introduction of the Wilks’ formula.
