Capacitively coupled ECG measurements - a CMRR circuit improvement

Health Monitoring in Smart Homes Utilizing Internet of Things

“…In [14] the authors integrate sensors in to a bathtub to monitor if a person becomes submerged or otherwise incapacitated while bathing. A chair with built in electrocardiogram (EKG) sensors is described in [15], which can monitor a patient with limited mobility who may spend long periods of time in the same location. Also, if patients with dementia are prone to wandering outside of the building, a caretaker can be alerted if the user has left at unusual hours or has been outside the building for an extended period of time.…”

“…Plans for aging in place will especially benefit from medical IoT in a smart home environment as the device network can be modified to accommodate different conditions that occur with age, some of which may be temporary, or have a sudden onset. Home modifications such as the bathtub in [14] and EKG measuring chair [15] are valuable with aging users who may be prone to falls or muscle weakness, and users undergoing serious treatment such a chemotherapy. It may be possible to mimic the behavior of the circuits presented in [14] and [15] on a smaller scale for triggering a response from the smart home system.…”

Managing medication and treatment will be possible with devices such as pill dispensers connected to the network to remind patients when it is time to take pills.…”

Non-Contact Monitoring of ECG in the Home Environment—Selecting Optimal Electrode Configuration

“…Each mentioned application demands a specific construction of the measurement system [ 10 ], e.g., to make the measurement system wearable, the electrodes are typically parts of the clothing. In general, the capacitive electrode for bioelectric potential measurements could be made of a multilayer printed circuit board [ 11 , 12 ] or a few layers of a conductive fabric [ 13 ]. The former solution makes it possible to locate the electronic measuring circuit (at least its input part) directly next to the capacitive electrode.…”
