Electrically driven heartbeat effect of gallium-based liquid metal on a ratchet
Frontiers in Bioengineering and Biotechnology, 2023 The realization of the liquid metal heartbeat effect shows better controllability under non-periodic stimuli than spontaneous oscillation or periodic stimuli.

Heartbeat stars and the ringing of tidal pulsations [PDF]
, 2015 With the advent of high precision photometry from satellites such as Kepler and CoRoT, a whole new layer of interesting and astounding astronomical objects has been revealed: heartbeat stars are an example of such objects. Heartbeat stars are eccen- tric

Peak Detection Algorithm for Vital Sign Detection Using Doppler Radar Sensors
Sensors, 2019 An accurate method for detecting vital signs obtained from a Doppler radar sensor is proposed. A Doppler radar sensor can remotely obtain vital signs such as heartbeat and respiration rate, but the vital signs obtained by using the sensor do not show ...

Spectrogram-Based Non-Contact RRI Estimation by Accurate Peak Detection Algorithm
IEEE Access, 2018 Demands for vital sign monitoring are increasing in the field of health care. In particular, the R-R Interval (RRI) estimation has been studied extensively, since the RRI variation is highly related with the stress of a subject.

Memory beyond memory in heart beating: an efficient way to detect pathological conditions [PDF]
, 2001 We study the long-range correlations of heartbeat fluctuations with the method of diffusion entropy. We show that this method of analysis yields a scaling parameter $\delta$ that apparently conflicts with the direct evaluation of the distribution of ...

Heartbeat and Somatosensory Perception [PDF]
NeuroImage, 2020 AbstractOur perception of the external world is influenced by internal bodily signals. For example, we recently showed that timing of stimulation along the cardiac cycle and spontaneous fluctuations of heartbeat-evoked potential (HEP) amplitudes influence somatosensory perception and the associated neural processing (Al et al., 2020).
