Recently, there are many reports on the measurement of mental health conditions as derived from physiological parameters – see references in [1]. Usually, heart-rate or heart rate variability (HRV) has been used for monitoring mental health because of its strong dependency on the autonomic nervous system (ANS) [1-2]. Reference [1] reported that ECG,(More)
—A low power highly sensitive Thoracic Impedance Variance (TIV) and Electrocardiogram (ECG) monitoring SoC is designed and implemented into a poultice-like plaster sensor for wearable cardiac monitoring. 0.1 TIV detection is possible with a sensitivity of 3.17 V and SNR 40 dB. This is achieved with the help of a high quality (Q-factor 30) balanced(More)
A wearable neuro-feedback system is proposed with a low-power neuro-feedback SoC (NFS), which supports mental status monitoring with encephalography (EEG) and transcranial electrical stimulation (tES) for neuro-modulation. Self-configured independent component analysis (ICA) is implemented to accelerate source separation at low power. Moreover, an embedded(More)
A 2.5 times 1.8 cm<sup>2</sup> medical implant communication service band antenna is combined with an electrode for body channel communication. The proposed design enables a body sensor network controller to communicate with health-care devices located on and inside a patient's body. The spiral microstrip antenna with its radiating body and ground plane(More)
A motion artifact reduction multi-channel bio-signal sensor is proposed for sleep monitoring system with the help of independent component analysis (ICA). To prevent signal saturation due to large motion artifacts, adaptive DC level control (ADLC) is adopted to adjust the DC level of the signal. The current-controlled level shifter (CCLS) is used in ADLC(More)
