Getting reliable sensor data is complex. For example, an optical heart-rate sensor is actually sensing the changes in an electric current. Heartbeats cause the volume of arterial blood to change synchronously with each pulse. The change in volume changes the amount of light absorbed and reflected as it travels through live tissue. When that light exits the tissue and enters a photodetector, it changes the output current. By creating a sensing system that carefully sets up a proper series of “dominos,” a current sensor becomes a heart-rate sensor.

When you’re exploring the depths of the ocean, it’s essential to know how much oxygen is left in your scuba tank, how deep underwater you are, ocean conditions, and other parameters. A wrist-worn diving computer can serve as your guide. One of the market’s most prominent developers of innovative dive technologies is Mares, based in Rapallo, Italy. Collaborating with ROJ, an Italian electronics designer, developer, and manufacturer, Mares has created the Genius wrist dive computer.

Wearable and handheld electronic design comes with an inherent tradeoff between battery life, feature richness, and size. To fit the most features in a small device, you want the smallest, most efficient power management scheme. For simple battery-powered devices, all you often need is a diode ORing. A diode ORing powers the device from the battery when unplugged and switches to the charging cable when plugged in. This simple scheme uses two diodes to select the option with the higher voltage. However, diodes have an inherent tradeoff between forward voltage, leakage, size and cost, where you generally get to pick two.

The Tesla Model 3 is changing our impression of the vehicle dashboard. Gone are the multiple gauges, buttons, and knobs that we’re accustomed to. Instead, when you step into the driver’s seat, the car’s 15-inch touchscreen takes center stage, providing access to all driver controls. When it comes to automotive displays, vehicle manufacturers are starting to incorporate more screens—and bigger, sharper ones—inside their cabins. Displays for functions such as advanced instrument clusters, heads-up displays, infotainment, center displays, rear-seat entertainment, and smart mirrors are delivering vivid images of the surrounding environment, automotive controls, and infotainment options.

What you don't know might hurt you. Such is the case with high blood pressure, or hypertension. "In terms of hypertension, the statistics are pretty frightening. Around a third of all people in the U.S. suffer from hypertension. Unfortunately about half of those don't know they have it," noted Andrew Baker during a November talk at IDTechEx Show! in Santa Clara.

The trouble with liking technology stuff is it keeps changing. Every year, there's something new you've gotta have. This winter, as we approach the end of the decade, there are, once again, lots of interesting tech items to consider for holiday gift-giving or just to buy for yourself. Here are just five of the best gifts for the engineer in your life.

More vehicle manufacturers are moving toward electrification, and sales of electric vehicles (EVs) are continuing to rise. While only 12% of the U.S. population, California provides nearly 50% of all EV sales in the country. Globally, China remains the leader in development and sales of EVs. By 2040, 57% of all passenger vehicle sales will be electric, according to BloombergNEF's analysis.

Hi Michael,
I've heard that gallium nitride (GaN) and silicon carbide (SiC) could replace MOSFET and IGBT power switches in the near future. The fact that they are smaller and faster sounds great, but as always, I suspect there's no such thing as a free lunch. Are there any pitfalls that I need to be aware of before I start looking at using GaN and SiC in my designs?

How much time do you spend designing power supplies? In this video, I will teach you how to design a power supply in five minutes or less using the online EE-Sim® Design and Simulation tool. The MAX17506 Evaluation Kit is used to compare efficiency simulation results from EE-Sim with the actual hardware. The results are nearly identical, which means designing hardware just got a whole lot easier. Don't believe me? Then have a seat, and enjoy the video!

Computing has seesawed between centralized and distributed models, from mainframes to enterprise servers and then to cloud computing. Each of these cycles has not completely replaced the previous architecture, but, rather, added to it to cater to differing needs past the hype cycle. With edge sensors and AI inferencing, we are now moving past the hype cycle for data centers towards increasing intelligence at the edge and processing the resulting data right there. With billions of edge devices, the demand for low latency has increased. It is incredibly inefficient to collect data from billions of edge devices to a central data center for computation when there is no inter-relationship among the data. Not to mention large, inefficient data pipes and high latency. This has opened the door for low-power, low-latency, distributed edge-computing devices.

Everyone is hoping that making buildings 'smart' will make them more environmentally sound, more livable, and more comfortable. About 40% of total U.S. energy consumption was attributed to buildings last year. Lower cost sensors and easier to implement networking are making a difference–especially in skyscrapers.

So you've got an idea for a new type of wearable, something that will accurately measure parameters such as blood pressure, heart rate, and blood-oxygen levels (SpO2). The market for these devices is hot, so you and your team want to time the launch of your device to the most opportune market window.

Hi, Michael:
I'm having a problem you might be able to help me out with. I'm designing an industrial sensor, but I'm struggling with the power budget to make it work with the IO-Link® connectors. The problem is that the regulators and LDOs on the IO-Link transceivers I've been looking at aren't efficient enough for the amount of current I need. Also, the sensor enclosure is too small for me to use a separate DC-DC converter. Any ideas?

In the mid 1970s I had the best job an aspiring engineer could hope for: I worked the sales floor at a well-known national electronics retailer. And at that time, there were just three products that kept us all in business: eight-track tape players, citizen's band radios, and police scanners.

The future of healthcare could be even more data-driven and personalized than it is today. Instead of determining that a patient has a light fever based on a thermometer reading of 37°C, a diagnosis would be based on a comparison of an elevated resting body temperature against a similarly observed baseline from that individual. Rather than an arbitrary (or worse, financially driven) model where patients visit their doctors for sparsely scheduled checkups, people may receive care based on a cadence optimized to their own unique situations.

Engineers designing the next generation of wearable health and fitness applications need high accuracy along with very low power for applications such as wrist-band wearables. The wrist is not an ideal location for clinical monitoring of body temperature, but gives a good relative and daily trend indication. Accuracy is still very important here.

I have a confession: I'm not really an analog person.
For pretty much my entire career, I've been working with microcontrollers and hooking them up to other, mostly digital, blocks. Freed from the uncertainties that plague the analog world, I could build large, complex systems out of digital logic, content in the knowledge that as long as I didn't push things too far, I could connect pretty much any digital output to pretty much any digital input, and the system would "just work."
