Piezo technologies4/26/2023 ![]() Retinal projection technology uses an ultra-low-powered laser to project the image directly onto the eyeball via an optical module built into the glasses’ frame (Fig. What’s needed is to overhaul the projection subsystem and other electronics so that the power consumption can deploy a smaller battery while providing all-day use. Alongside other electronics, the battery also can impact the form factor. ![]() Today’s waveguide projection systems require higher-power laser to project the image, which drives the size of the battery required. Bulky and heavy AR glasses may only be worn 15-20 minutes before the nose, ears, or temples start to feel uncomfortable. The usability issue depends heavily on two factors: weight and form factor. The lack of long-term usability is a big problem in the augmented-reality (AR) space. Augmented Reality with Retinal Projection This proactive approach to road maintenance also eliminates the need for the public to send emails or make calls to the local municipality, saving valuable resources. By mapping out this real-time information, local municipalities know which roads to fix. In addition, this technological solution benefits the driver, the car maker, the tire maker, and overall customer relations.įrom a societal point of view, this data also provides a new way of crowdsourcing road health data, for example, relating to potholes. These analytics support high-performance driving, autonomous vehicles, safety, comfort, and energy savings. 1), delivers data analytics, obtained at the wheel, directly to the vehicle and/or to cloud-connected vehicle-to-everything (V2X) devices. Besides tire pressure and tread depth, possibilities include tire wall temperature, road surface conditions, and wheel alignment.įor example, the TDK piezo-powered sensor platform, called InWheelSense (Fig. A piezo-powered sensor inside the wheel can harvest energy as the car is being driven and charge that same coin battery, prolonging its lifetime. Interestingly, piezoelectric materials can harvest energy from vibration and movement. ![]() And let’s face it, nobody wants to take their car to the shop to change the battery every six months. If you put Bluetooth in there, for example, the original coin-cell battery will probably last for between six and 12 months. The two-digit number I mentioned in the existing tire-pressure monitoring systems doesn’t support high data rates. More sensors in the wheel will consume more power and gaining access to this data requires better communication. The tire maker could leverage the data to send a text message, email, or notification, advising the owner to visit the shop for a change with the same tire brand. While this data is fundamental for driver comfort and safety, it creates new revenue streams, such as recurring tire sales. For example, information about a low tire tread could advise the driver to change the tire before a blowout occurs. Instead of just transmitting the tire’s pressure from the wheel, we could get data from other sensors for the smart, connected wheel of the future. These pressure sensors run on a tiny coin-cell battery with a lifetime of anywhere from eight to 10 years-nobody thinks much of it. Most modern cars come equipped with a tire-pressure monitoring system that displays four simple two-digit numbers on the dashboard. This article outlines two technological solutions that are set to revolutionize the industry and our lives in 2022. These solutions provide critical functionality in connectivity, IoT systems, healthcare, robotics, energy, user experience, and mobility, well beyond the component level.īut without certain electronic components, many solutions we take for granted these days might never have come about.
