Photodetectors Endowing photodetectors with mechanical flexibility and actual functionality are current research issues in developing optoelectronic devices. In article number 2201303, Xiaosheng Fang co-workers report an all-organic self-powered photodetector prepared by all-solution method ultraflexible dual-polarity output, which can be utilized detecting steady biosignals for photo-plethysmo...

Background Chronic obstructive pulmonary disease (COPD) is the fourth most common cause of death in the world, for which smoking is a common cause. It is preferable to diagnose COPD at an earlier stage and to assess its progression so that mortality and morbidity of the disease could be reduced. Hence, we conducted this study to assess parameters of body plethysmography in Indian population whe...

In order to clarify the nature of the regulatory mechanism of the hyperventilation observed at the transition from rest to exercise, cardiac output and ventilation changes in response to submaximal bicycle exercise given as a step function were studied in five healthy men. Cardiac output was determined non-inversively by using a type of impedance plethysmography. It was found that (1) both the ...

Background: We measured Functional Residual Capacity (FRC) of the lungs with three methods in healthy volunteers. The three techniques included a CO2 partial rebreathing technique, nitrogen washout technique, and the reference technique for ambulatory patients, body plethysmography. Materials and Methods: After granting consent to an IRB-approved protocol, each of the 20 healthy volunteers part...
