This paper presents a lossless sensor data compression accelerator for power reduction in wireless body sensors. First, a low complexity compression algorithm is demonstrated for the first time on electrocardiogram (ECG) and acceleration sensor data. Second, the algorithm is implemented as a custom hardware accelerator on a health monitoring driven System on Chip (SoC) in a 130 nm process. The accelerator...
This study advances the technology for “smart” antenna stents integrated with micro pressure sensors, targeting at providing a non-invasive and rapid diagnosis of stenting-induced complications in a wireless manner. The smart stent device is developed via considering both engineering and clinical practicality with enhanced electromechanical performance over reported counterparts. The fabricated prototypes...
A radio-frequency (RF) interrogation method for sensor-integrated “smart” stent implants is reported. This device, formed with a 2-cm-long inductive antenna stent and a micro capacitive pressure sensor, both based on a medical-grade stainless steel, serves as a wireless resonant pressure sensor designed to detect changes in local blood pressure for early detection of post-stenting complications. Wireless...
