Tiny heat pump that relies on changing ambient temperature could be key to powering IoT devices and sensors without batteries forever — Nanoparticles are critical to the process, posit scientists

[ad_1]

As IoT technology progresses, the question of how to power these devices, particularly in locations where reliable electrical sources are scarce, presents a significant challenge. 

Researchers at the University of Utah’s College of Engineering have pioneered a new form of battery that could help solve this dilemma. The solution, which is at the proof of concept stage, comes in the form of a pyroelectrochemical cell (PEC).

Sennheiser Momentum Sport wireless earbuds that track heart rate and body temperature finally started shipping this week after their big reveal in January at CES 2024.

Heart rate and body temperature sensors were expected in AirPods Pro (2nd generation), launched in September 2022, but didn’t end up in the product (yet).

Sennheiser Momentum Sport wireless earbuds

Sennheiser first unveiled Momentum Sport at CES 2024, but then took a while to start shipping them.

The new Momentum Sport true wireless earbuds are optimized for fitness via real-time biometric feedback. Integrated photoplethysmography (PPG) heart rate and body temperature sensors output data to popular fitness apps and devices.

Heart rate data connects with popular sport devices and apps, according to the company. Devices and apps include Apple Watch/Health, Garmin Watch/Connect, Strava, Peloton and others.

“For the first time ever in a non-Polar product, users will be able to enjoy full access to Polar’s elite biosensing capabilities and data analytics — including Body Temperature — offering real-time insights during training and deeper offline analysis via the Polar Flow app ecosystem,” Sennheiser noted. Polar joined forces with Sennheiser in January.

Top features per Sennheiser:

  • To minimize footstep noise, breathing and other body-borne distractions, the earbuds feature an acoustic relief channel and semi-open design for natural environmental awareness.
  • An adjustable Transparency mode, Anti-wind mode, and Adaptive Noise Cancelling mode let the wearer easily adapt as their surroundings change.
  • The all-new acoustic system features a redesigned transducer that handily delivers the best sound quality yet in a Sennheiser sport earbud.

Momentum Sport details:

  • Colors: colors: polar black, burned olive and metallic graphite
  • IP55 sweat and water resistance
  • Shock-proof chassis
  • Clog-resistant ear tips
  • IP54-rated, Qi-enabled carrying case stores up to three additional earbud recharges (up to 24 hours of playtime).
  • 10 minutes of USB-C quick-charging provides up to 45 minutes of playback.
  • Cost: $329.95

What is the best temperature for sleep?

[ad_1]

When you’re curled up on your best mattress, it can feel like the rest of the world simply disappears. But as comfortable as your bedding cocoon might be, if you want to get the best night’s sleep, then it’s important to consider your entire sleep environment – and that includes the temperature in your bedroom. 

“We suggest maintaining a cool bedroom temperature for optimal sleep,” says James Higgins, founder and CEO of Ethical Bedding. “It supports the body’s natural dip in core temperature that occurs during sleep, promoting deeper and more restful sleep cycles.” In the bedroom, this translates to an ambient temperature around roughly 65 degrees Fahrenheit / 18 degrees Celsius.
