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 β€œthere 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 ST1VAFE3BX biosensor

STMicroelectronics (STMicro) has announced the ST1VAFE3BX biosensor, a highly integrated chip that combines β€œcardio 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 β€œto 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 [...]

Raytac AN7002Q – A smaller nRF7002 Wi-Fi 6 module for industrial IoT applications

28 September 2024 at 08:28
AN7002Q-P module

IoT solutions company Raytac has introduced the AN7002Q Wi-Fi 6 module series, which integrates Nordic Semiconductor’s nRF7002 chipset and is designed for Industrial IoT, smart home, healthcare, consumer electronics, and automotive applications. They can be paired with Raytac’s MDBT53 Bluetooth LE modules based on the nRF5340 multiprotocol SoC, supporting Wi-Fi and Bluetooth LE solutions. The AN7002Q is a low-power Wi-Fi 6 module supporting dual-band 2.4 GHz and 5 GHz operation with a maximum PHY data rate of 86 Mbps (MCS7). It is compatible with IEEE 802.11ax, a/b/g/n/ac standards, and connects to a host SoC or MCU via SPI or QSPI interfaces. The module also supports coexistence with Bluetooth LE, Thread, and Zigbee systems, making it ideal for IoT applications. Previously, we covered the Abluetech PTR7002, a low-power wireless module based on the Nordic Semiconductor nRF7002. The PTR7002 has a slightly larger size and offers more GPIO options, while the AN7002Q [...]
