The driving force for the development of consumer smart electronic products

In the past few years, smoother and more efficient connection technology has undoubtedly inspired the development direction of the consumer electronics industry, and the global sales of consumer smart devices are still rising steadily. Taking the mobile phone market as an example, thanks to the comprehensive penetration of 5G technology from high-end phones to low-end phones, smart home, smart office and other Internet of Everything models centered on smartphones are starting. At the same time, as important accessories for smart life, portable electronic products and wearable electronic devices that support multiple connection technologies are being favored by consumers.

In order to bring consumers a smarter and more convenient experience, responsive and accurate sensors are an indispensable and important accessory for building successful consumer smart products. As a monitoring device, the sensor is used to sense signals in the surrounding reality, such as smell, distance, color, strength, etc. Putting sensors on an electronic device means putting on the senses (touch, taste, smell, sight, etc.). In this way, equipped with sensors, electronic devices can be more intelligent, and can accurately perceive the surrounding environment, so that it can automatically respond. At the same time, power consumption affects the product use time of the sensor, and it is one of the important factors affecting the product life. Only sensors with high accuracy, good power consumption control, and higher compliance can make intelligent electronic devices more competitive.

In response to this trend, recently, Semtech (Semtech), the world’s leading supplier of high-performance analog and mixed-signal semiconductor products and advanced algorithms, announced the launch of PerSe™, a smart sensor platform for the consumer smart device market. The PerSe product portfolio consists of three core product lines, PerSe Connect, PerSe Connect Pro and PerSe Control, which bring breakthrough user experiences to smartphones, laptops, tablets and wearable devices by intelligently and automatically sensing the presence of the human body. It has injected innovative vitality into the field of consumer smart devices in the Internet era.

Technology is in the details

Overall, PerSe sensors are able to intelligently sense the presence of users in the vicinity of mobile devices and other consumer electronics, and initiate advanced radio frequency (RF) control when the user approaches. PerSe sensors have unique smart human sensing capabilities, ultra-low power consumption and ultra-small footprint, making them an ideal sensing solution for various mobile portable devices or wearable applications such as gesture control and automation.

The core technology of PerSe is mainly reflected in two aspects:

Improve connection performance.Optimizes RF power for maximum performance in smartphones, tablets, laptops, and 5G and Wi-Fi 6 applications, while meeting the world’s most stringent compliance standards; PerSe smart sensors sense the presence of the human body, based on the sensing results And demand, automatic realization of radio frequency control.

Intuitive control functions.Provide “wear and go” functions such as automatic on/off, smart assistant startup and media control for wearable devices such as headphones and smart watches to improve user experience; PerSe smart sensors can realize fast response to different functions and simplify user interaction.

With the addition of core technical advantages, the characteristics of PerSe series products are mainly reflected in three aspects:

First-class performance. Superior analog front end design with excellent performance for longer sensing distance or more sensitive sensing; high signal-to-noise ratio analog signal and digital signal processing chain for higher immunity to interference.

Built-in intelligence. The innovative intelligent human body sensing function can distinguish between the human body and non-living objects, and improve the response effect of the device.

Temperature compensation. The advanced temperature compensation function minimizes false triggering, helps the device reduce power consumption and achieve longer battery life.

Focusing on the application field of the product itself, the three PerSe products of Semtech have their own merits and focuses on performance for each target industry:

PerSe Connect: Enhanced connectivity (5G Sub-6, 4G and Wi-Fi 6) for many smartphones, tablets and laptops worldwide. This family of sensors helps optimize RF power for optimal connection performance, maintaining SAR compliance while delivering a fast wireless experience.

PerSe Connect Pro: The first sensor product to provide ultra-high sensing performance for high-band 5G mmWave devices in smartphones, laptops and tablets. This family of sensors enables longer sensing distances to more effectively manage increased RF exposure.

PerSe Control: Enable smarter controls in wearables to improve user experience. This series of sensors enables human detection, automatic switching and start/stop response. It also offers state-of-the-art gesture controls and responses, including Assistant, Noise Cancellation Activation, and Media Player Control.

“Smart devices need smart sensors to stand out from the competition.” Joe Hoffman, research director of edge smart sensing technology at SAR Insight, expressed the core role of sensors, and believes that products that pay attention to technical details can be competitive in the market: ” Mobile, portable and wearable devices complicate the design balance of performance, battery life and RF absorption in the human body. Semtech’s PerSe series of smart sensors can distinguish between human and inanimate objects, including hand-held position. This leading transmitter Sensing capabilities are critical for mobile, wearable and 5G mmWave devices to provide a superior user experience.”

The market demands compliant and reliable products

In recent years, the market demand for high-end consumer electronics products has been strong, and providing consumers with a more compliant and reliable user experience has attracted widespread attention.
