Two novel wireless fabric patch sensors are introduced for low energy wearable healthcare. The first is a wirelessly powered patch sensor that can be attached to a patient to capture electrocardiogram (ECG) while consuming only 12μW. By using fabric circuit board technology, the band-aid like sensor is implemented. The second wearable cardiac heathcare sensor, fabricated in the form of 4-layer compact...
This paper presents a self-configured wearable BSN system with high efficiency wirelessly powered sensors that continuously monitor ECG and other vital signals at the selected locations on the body with low power consumption.
A low-energy inductive coupling link with a low energy fault-tolerant wearable body sensor network (BSN) controller is proposed to realize intra- and cross-layer wearable network at once. The intra-layer switch adopts the hybrid routing scheme to achieve fault-tolerance, and the cross-layer inductive transceiver employs the resonance compensator with an on-chip capacitor bank and a variable hysteresis...
A healthcare monitoring system with wireless woven inductor channels is proposed for body sensor networks. A sensor node with the proposed woven inductor channel consumes only 300 uW for sensing and 340 uW for communication with 1 Mbps data rate. The personal sensor controller consumes 8 mW, and the efficiency is 178 times than the previous work.
A body sensor network (BSN) system needs ultra-low power consumption to provide a user-friendly small form-factor. This paper presents the dual-mode system architecture to manage 254 nodes in the BSN with low-power consumption. Its instantaneous program execution with external program counter scheme prohibits unnecessary RISC operation and wakes up the RISC from its turn-off state just in 3-clock...
