Comparison of Current and Novel ECG-Independent Algorithms for Resting Pressure Derived Physiologic Indices

IEEE Access, 2019
Recently, instantaneous wave-free ratio (iFR) or diastolic pressure-ratio (dPR) have been used in practice. For these indices, the reliability of electrocardiography (ECG)-independent algorithm for pressure-only data is essential.

Functional coronary assessment: instantaneous wave-free ratio and other indices

, 2018
The instantaneous wave-free ratio (iFR) is a hyperaemia-independent coronary pressure index for the physiological assessment of coronary stenoses. The underlying concept of iFR is that it quantifies the trans-stenotic pressure ratio during the wave-free ...

Skin‐Like Tri‐Modal Sensors Based on Soft Piezoelectric and Ionic Composites

Advanced Materials Technologies, EarlyView.
Inspired by the multimodal perception of human skin, a soft, skin‐like tri‐modal sensor is presented. The device incorporates an ionically conductive, piezoelectric, elastic composite as its active layer, enabling independent detection of temperature, static strain, and dynamic strain within a single two‐terminal architecture.

Laser‐Induced Local De‐Doping in Organic Semiconductors

Advanced Materials Technologies, EarlyView.
The polymer PBTTT‐C14 doped with the small molecule acceptor F4TCNQ is considered as a benchmark material system. Mask‐free, microscale patterning of the doping level via laser‐induced heating and sublimation of dopant molecules is shown. Controlling laser irradiance and swath spacing allows dopant level control with laser‐limited resolution, opening ...

Coronary Flow Capacity to Identify Stenosis Associated With Coronary Flow Improvement After Revascularization: A Combined Analysis From DEFINE FLOW and IDEAL

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Coronary flow capacity (CFC), which is a categorical assessment based on the combination of hyperemic coronary flow and coronary flow reserve (CFR), has been introduced as a comprehensive assessment of the coronary circulation to overcome the ...

Toward Perception‐Native Electronic Skin: Bio‐Inspired In‐/Near‐Sensor and Neuromorphic Computing for Humanoid Robots

Advanced Materials Technologies, EarlyView.
Dense tactile streams from across the humanoid body converge on collide in a central wiring and data bottleneck. By relocating computation closer to and then into the skin itself, near‐ and in‐sensor architectures, together with neuromorphic computing, chart a path toward perception‐native electronic skin, in which the conversion of stimulus into ...
