Wirelessly powered electronics developed by KAUST researchers could help to make internet of things technology more environmentally friendly.
« A greener internet of things with no wires attached
Newswise — Emerging forms of thin-film device technologies that rely on alternative semiconductor materials, such as printable organics, nanocarbon allotropes and metal oxides, could contribute to a more economically and environmentally sustainable internet of things (IoT), a KAUST-led international team suggests.
The IoT is set to have a major impact on daily life and many industries. It connects and facilitates data exchange between a multitude of smart objects of various shape and size — such as remote-controlled home security systems, self-driving cars equipped with sensors that detect obstacles on the road, and temperature-controlled factory equipment — over the internet and other sensing and communications networks.
This burgeoning hypernetwork is projected to reach trillions of devices by next decade, boosting the number of sensor nodes deployed in its platforms.
Current approaches used to power sensor nodes rely on battery technology, but batteries need regular replacement, which is costly and environmentally harmful over time. Also, the current global production of lithium for battery materials may not keep up with the increasing energy demand from the swelling number of sensors.
Wirelessly powered sensor nodes could help achieve a sustainable IoT by drawing energy from the environment using so-called energy harvesters, such as photovoltaic cells and radio-frequency (RF) energy harvesters, among other technologies. Large-area electronics could be key in enabling these power sources.
KAUST alumni Kalaivanan Loganathan, with Thomas Anthopoulos and coworkers, assessed the viability of various large-area electronic technologies and their potential to deliver ecofriendly, wirelessly powered IoT sensors.
Large-area electronics have recently emerged as an appealing alternative to conventional silicon-based technologies thanks to significant progress in solution-based processing, which has made devices and circuits easier to print on flexible, large-area substrates. They can be produced at low temperatures and on biodegradable substrates such as paper, which makes them more ecofriendly than their silicon-based counterparts.
Over the years, Anthopoulos’ team has developed a range of RF electronic components, including metal-oxide and organic polymer-based semiconductor devices known as Schottky diodes. “These devices are crucial components in wireless energy harvesters and ultimately dictate the performance and cost of the sensor nodes,” Loganathan says.
Key contributions from the KAUST team include scalable methods for manufacturing RF diodes to harvest energy reaching the 5G/6G frequency range. “Such technologies provide the needed building blocks toward a more sustainable way to power the billions of sensor nodes in the near future,” Anthopoulos says.
The team is investigating the monolithic integration of these low-power devices with antenna and sensors to showcase their true potential, Loganathan adds.

Metro Board to Consider Locally Preferred Alternative for Sepulveda Transit Corridor Project
Metro Board will consider Modified Alternative 5 as the Locally Preferred Alternative for the Sepulveda Transit Corridor Project on January 22, 2026, a major step toward improving transit between the San Fernando Valley and LA’s Westside.
On Thursday, January 22, 2026, at 10:00 AM, the Metro Board will consider selecting a Locally Preferred Alternative (LPA) for the Sepulveda Transit Corridor Project. This milestone could significantly improve mobility options between the San Fernando Valley and the of Los Angeles.
Proposed Alternative
After a technical evaluation and reviewing more than 8,000 public comments from the Draft Environmental Impact Report (Draft EIR) period, Metro staff has proposed Modified Alternative 5 as the LPA. This underground heavy rail line would run between the Van Nuys Metrolink Station and the E Line Expo/Sepulveda Station with a key connection to the G Line at Van Nuys Boulevard.
Modified Alternative 5 combines the benefits of Alternative 5—high ridership, frequent service, and shorter station construction sites—while avoiding geographic challenges in the Santa Monica Mountains. It also incorporates connectivity advantages from Alternative 6 along Van Nuys Boulevard, reducing the overall project length and anticipated costs, and increasing direct connections to Metro’s growing transit network.
Next Steps
If approved, Metro would advance project development for the LPA, including:
- Evaluating phasing and the Public/Private Partnership (P3) delivery model
- Identifying value engineering opportunities
- Refining designs to allow G Line connection at Van Nuys Boulevard
- Continuing environmental review and community outreach
Public Participation
Residents, businesses, and institutions are encouraged to provide feedback:
- Attend in person: Sign up on the tablets in the Metro Headquarters lobby before 9:45 AM.
- Email comments: BoardClerk@metro.net (comments received before 5 PM on January 21, 2026, will be sent to the full Board)
- Watch live: boardagendas.metro.net
Why This Matters
The Sepulveda Transit Corridor Project will connect the San Fernando Valley to the Westside, addressing the natural barrier of the Santa Monica Mountains and relieving congestion on the I-405. It will provide a fast, safe, and reliable alternative to the freeway and strengthen LA’s regional transit network.
Disclaimer: Station locations and construction timelines are subject to change. Project availability may vary. Public input is encouraged before final decisions are made.
Continuing Coverage: STM Daily News will continue to follow developments surrounding the Sepulveda Transit Corridor Project, including Metro Board decisions, environmental review updates, community input opportunities, and the project’s long-term impact on transportation across Los Angeles.

Major Popeyes Franchisee Sailormen Files for Chapter 11 — What It Means for Restaurants and the Economy
Sailormen Inc., a major Popeyes franchisee operating 130+ locations in Florida and Georgia, filed for Chapter 11 on Jan. 15, 2026 amid rising costs and heavy debt. Many restaurants are expected to remain open as restructuring continues.
A major Popeyes Louisiana Kitchen franchise operator is heading to bankruptcy court — but the headline does notmean Popeyes corporate is filing, or that every restaurant involved is about to close.
Sailormen Inc., a Miami-based Popeyes franchisee that has operated in the system since 1987, filed for Chapter 11 bankruptcy protection on Jan. 15, 2026. The company operates more than 130 Popeyes locations across Florida and Georgia (some industry coverage puts the count at 136), making it one of the chain’s largest franchise groups in the region.
Franchisee filing, not a Popeyes corporate bankruptcy
This case involves Sailormen (the operator) — not Popeyes corporate and not parent company Restaurant Brands International.
In a message referenced in industry reporting, Popeyes leadership said Sailormen’s filing does not reflect the overall health of the Popeyes brand, and that a large majority of Sailormen’s restaurants are expected to remain open while the company restructures.
What pushed Sailormen into Chapter 11
Court-related summaries and industry coverage point to a familiar mix of pressures hitting restaurant operators:
- Inflation and higher operating costs (food, labor, and day-to-day expenses)
- Higher borrowing costs as interest rates climbed
- Liquidity strain, including reports of falling behind on rent and facing pressure from landlords and vendors
- Legal disputes, including vendor-related claims tied to unpaid balances
The failed store sale that worsened the situation
One key detail: Sailormen reportedly tried to sell 16 Georgia restaurants to stabilize finances. That deal fell through, and the company remained responsible for lease guarantees tied to those locations — a liability that can linger even if other stores are performing.
The debt and the lender pressure
Industry reporting describes Sailormen as carrying a heavy debt load — cited at about $130 million overall.
More detailed figures cited in coverage include:
- Over $112 million in unpaid principal loan balance
- Over $17 million in accrued interest and fees
Reporting also points to pressure from BMO (BMO Bank), described as Sailormen’s largest lender. In December 2025, BMO reportedly sought to appoint a receiver, a move that can displace management and take control of a company’s assets. Sailormen’s Chapter 11 filing allows the company to continue operating as a debtor-in-possession while it attempts to reorganize.
Why this matters for “Food” and “Our Economy”
This isn’t just a Popeyes story — it’s a snapshot of what happens when restaurant operators face higher costs, value-conscious consumers, and more expensive debt at the same time.
Chapter 11 is designed to reorganize a business, not automatically liquidate it. For customers, the near-term impact may be limited if most locations stay open.
STM Daily News will follow this story as it develops, including any updates on store operations, restructuring plans, and potential sales of locations.
