The new EVK2 enables customers to easily integrate analog machine learning and analog data compression into battery-operated voice-enabled devices, such as hearables/wearables, smart speakers, and smart TV remotes, facilitating […]
Board to FPC narrow pitch connectors for wearable devices
Panasonic Corp. announced today that its Industrial Solutions Co. has commercialized the R35K series of board to FPC narrow pitch connectors for use in wearable devices and will launch full scale mass production this month. The new connectors reduce the board mounting areas and are configured to be highly resistant to vibrations and impacts, contributing […]
RISC-V is growing and offers stability, scalability and security
RISC-V is growing rapidly. Semico Research has projected that 62.4 billion RISC-V CPU cores will be sold in 2025. While that’s only about 6% of the overall CPU core market, RISC-V is an emerging technology that most designers should follow and become increasingly familiar with. RISC-V is becoming more commercially attractive as a result of […]
Battery life analysis and maximization for wireless IoT sensor nodes and wearables
In addition to proper hardware design and power consumption testing, an accurate estimation of battery life is an important aspect of designing wireless Internet of Things (IoT) sensor nodes and wearables. For some medical or industrial devices, in particular, users’ lives can be at stake if the battery does not live up to expectations. Some […]
Batteries and charging for wireless IoT nodes and wearables
Battery selection for a given wireless Internet of Things (IoT) node or wearables design is complex. Among the important factors are: how long the device is expected to operate with a single battery; the choice between various primary and secondary battery chemistries; the nominal and cut-off voltage of the electronics; the energy/current consumption profile, the […]
Power conversion considerations for wireless IoT sensor nodes and wearables
Power system considerations are an important aspect of all system designs. In the case of wireless Internet of Things (IoT) nodes and wearables, power system design is complex, with the need to balance numerous performance tradeoffs. It is critical to arrive at a successful design that maximizes both battery life and overall functionality. Fortunately, there […]
