Double‐Sided Conformable Piezoelectric Force Sensor with Enhanced Performance and Bending Correction
Advanced Electronic Materials, EarlyView.This work addresses the challenge of measuring low forces on soft surfaces. An innovative conformable piezoelectric force sensor is presented. The use of a highly flexible TPU substrate enables a tenfold increase in the sensor's sensitivity to compression while a double‐sided structure prevents the signal from being disturbed by bending due to ...

The Cardiac Sarcomere and Cell Cycle
Current Cardiology Reports, 2022The lack of adult human cardiomyocyte proliferative capacity impairs cardiac regeneration such as after myocardial injury. The sarcomere, a specialized actin cytoskeletal structure that is essential for twitch contraction in cardiomyocytes, has been considered a critical factor limiting adult human cardiomyocyte proliferation through incompletely ...

The phases of the cardiac cycle
American Heart Journal, 1972Abstract The events of the cardiac cycle are re-evaluated on the basis of newer ideas of inertial states, compliance, and similar hemodynamic principles by the use of more precise, modern recording equipment. While these events generally agree with classic schemes, certain discrepancies which tend to cause inaccurate measurement are presented.

Oscillations of cAMP with the cardiac cycle
Biochemical and Biophysical Research Communications, 1983Oscillations of cAMP with the cardiac cycle were demonstrated in the rat heart using a stimulator-triggered rapid freeze-clamp to decrease the temperature of the heart from 37 degrees C to -80 degrees C in 5 msec (20,000 degrees/sec) at a predetermined phase of the cardiac cycle. The nucleotide, cAMP, oscillated 60% with the cardiac cycle during normal

Abstract The heart consists of four chambers that are connected in such a way that contraction of them causes the heart to act as a pump, the right half of the heart passing blood from the venae cavae to the pulmonary circulation for oxygenation and the left half of the heart pumping oxygenated blood from the pulmonary veins into the aorta and ...
