Murata unveils stretchable PCB technology for medical and bio-sensing applications

Murata Stretchable PCB

Many PCB vendors now provide flexible PCB manufacturing services, but Murata goes further with stretchable PCB technology that’s not only bendable but can be twisted and stretched to better fit on the body for bio-sensing and medical applications even on parts such as an elbow. Traditional bio-monitoring sensors have some limitations. For example, they can become unstuck when the body moves, damage the delicate skin of infants and the elderly, data may be distorted due to body movement, and Murata explains “there is a risk of a decline in insulation and the occurrence of ion migration when using a thermoplastic polyurethane elastomer (TPU), known as a stretchable base material, in a high humidity environment”. The company’s stretchable printed circuits ((SPC) are supposed to solve or at least mitigate all those issues. The technology is under development, but Murata still shared some highlights of the technology: Stretchable electrode printing in compliance […]

STMicro’s low-power ST1VAFE3BX AI biosensor integrates biopotential signal monitoring and motion tracking

STMicro ST1VAFE3BX biosensor

STMicroelectronics (STMicro) has announced the ST1VAFE3BX biosensor, a highly integrated chip that combines “cardio and neurological sensing with motion tracking and embedded AI functionalities,” and is targeted at healthcare and fitness wearables. The ST1VAFE3BX biosensor chip integrates biopotential inputs with an accelerometer and a machine learning core for reduced power consumption. It features a complete vertical analog front end (vAFE) for simplified detection of vital signs in electrocardiography, electroencephalography, and other healthcare monitoring applications. Inertial sensing by the accelerometer is synchronized with biopotential sensing “to infer any link between measured signals and physical activity.” The integrated machine-learning core (MLC) and finite state machine (FSM) allow for ultra-low-power and accurate biopotential input recognition at a degree of responsiveness that is reportedly faster than the current industry standard. The ST1VAFE3BX is aimed at applications in healthcare and fitness wearables such as smartwatches, smart patches, sports bands, connected rings, and smart glasses. It […]
