A customizable electronic pill capable of delivering medication via wireless commands from inside the body has been developed by researchers at MIT, Draper, and Brigham and Women’s Hospital, all in Massachusetts. As described in a paper published in the December 13, 2018 issue of Advanced Materials Technologies, this ingestible device could provide a system of monitoring and treating medical conditions typically requiring injections or strict dosing regiments such as HIV and malaria. Early signs of disease or adverse reaction could be also detected with onboard sensors in at-risk patients, such as those receiving chemotherapy or immunosuppressants, and medicine dispensed accordingly. Tests of similar devices have begun using pigs, and the researchers estimate human trials to start in about two years.

The electronic pill is a Y-shaped compartmented device whose legs have been folded into a smooth capsule that dissolves once swallowed. After the legs unfold again, it lodges into the stomach where it remains for approximately one month before being broken down and fully digested. The scientists in the study anticipate that the pill’s compartments could be designed to be opened using low-energy wireless communication technology such as Bluetooth to release specified amounts of medication. Further, sensors in the pill could connect to other wearable devices, creating an all-in-one communication tool and treatment system connecting the patient’s health data to theirs or their doctor’s smartphone.

The scientific team used 3D printing to manufacture the pill due to the versatility offered. The layer-by-layer process of the printing technology is complementary to the internal architecture needed for the device to function as intended. It also enables fully customized material to be designed and used for the device’s construction to withstand the environments it would be exposed to inside the human body. 3D printing additionally makes further customization easily accessible as its capabilities expand.

There are several reasons why an ingestible pill would be a desirable option in medical practice despite numerous technologies and treatment methods available for similar purposes. In the case of burn or trauma patients, limiting skin contact in vital sign monitoring would be an important improvement, especially in cases where no contact at all is possible. The challenges of collecting accurate data from external sensors to diagnose problems like abnormal heart rhythms or breathing problems could be also overcome by an ingestible device, especially those where patients must monitor themselves without direct medical assistance.

The researchers in this study were previously involved with other ingestible technologies, one having been a capsule specifically designed to detect heart and breathing rates in a digestive system environment. A tiny microphone component packed inside a silicone capsule with electronics for processing utilized the sound waves produced by heartbeats and movement of air through the lungs to gather heart rate and respiratory rate data. The successful experiment provided a foundation for the medication delivery version to build on.

Liu Tao, co-CEO of IM Motors, has publicly apologized to Tesla China for comments he made in 2022 suggesting a Tesla vehicle was defective following a fatal traffic accident in Chaozhou, China. 

Liu said later investigations showed the accident was not caused by a brake failure on the Tesla’s part, contrary to his initial comments.

IM Motors co-CEO issues apology

Liu Tao posted a statement addressing remarks he made following a serious traffic accident in Chaozhou, Guangdong province, in November 2022, as noted in a Sina News report. Liu stated that based on limited public information at the time, he published a Weibo post suggesting a safety issue with the Tesla involved in the crash. The executive clarified that his initial comments were incorrect.

“On November 17, 2022, based on limited publicly available information, I posted a Weibo post regarding a major traffic accident that occurred in Chaozhou, suggesting that the Tesla product involved in the accident posed a safety hazard. Four hours later, I deleted the post. In May 2023, according to the traffic police’s accident liability determination and relevant forensic opinions, the Chaozhou accident was not caused by Tesla brake failure.

“The aforementioned findings and opinions regarding the investigation conclusions of the Chaozhou accident corrected the erroneous statements I made in my previous Weibo post, and I hereby clarify and correct them. I apologize for the negative impact my inappropriate remarks made before the facts were ascertained, which caused Tesla,” Liu said. 

Investigation and court findings

The Chaozhou accident occurred in Raoping County in November 2022 and resulted in two deaths and three injuries. Video footage circulated online at the time showed a Tesla vehicle accelerating at high speed and colliding with multiple motorcycles and bicycles. Reports indicated the vehicle reached a speed of 198 kilometers per hour.

The incident drew widespread attention as the parties involved provided conflicting accounts and investigation details were released gradually. Media reports in early 2023 said investigation results had been completed, though the vehicle owner requested a re-investigation, delaying the issuance of a final liability determination.

The case resurfaced later in 2023 following a defamation lawsuit filed by Tesla China against a media outlet. According to a court judgment cited by Shanghai Securities News, forensic analysis determined that the fatal accident was unrelated to any malfunction on the Tesla’s braking or steering systems. The court also ruled that the media outlet must publish an apology, address the negative impact on Tesla China’s reputation, and pay a penalty of 30,000 yuan.

SpaceX is reportedly exploring new products tied to Starlink, including a potential Starlink-branded phone. 

The update was reportedly shared to Reuters by people familiar with the matter. 

A possible Starlink Phone

As per Reuters’ sources, SpaceX has reportedly discussed building a mobile device designed to connect directly to the Starlink satellite constellation. Details about the potential device and its possible release are still unclear, however.

SpaceX has dabbled with mobile solutions in the past. The company has partnered with T-Mobile to provide Starlink connectivity to existing smartphones. And last year, SpaceX initiated a $19.6 billion purchase of satellite spectrum from EchoStar.

Elon Musk did acknowledge the idea of a potential mobile device recently on X, writing that a Starlink phone is “not out of the question at some point.” Unlike conventional smartphones, however, Musk described a device that is “optimized purely for running max performance/watt neural nets.” 

Starlink and SpaceX’s revenue

Starlink has become SpaceX’s dominant commercial business. Reuters’ sources claimed that the private space company generated roughly $15–$16 billion in revenue last year, with about $8 billion in profit. Starlink is estimated to have accounted for 50% to 80% of SpaceX’s total revenue last year.

SpaceX now operates more than 9,500 Starlink satellites and serves over 9 million users worldwide. About 650 satellites are already dedicated to SpaceX’s direct-to-device initiative, which aims to eventually provide full cellular coverage globally.

Future expansion of Starlink’s mobile capabilities depends heavily on Starship, which is designed to launch larger batches of upgraded Starlink satellites. Musk has stated that each Starship launch carrying Starlink satellites could increase network capacity by “more than 20 times.”

The Federal Communications Commission (FCC) has accepted SpaceX’s filing for a new non-geostationary orbit (NGSO) satellite system of up to one million spacecraft and has opened the proposal for public comment. 

The move formally places SpaceX’s “Orbital Data Center” concept into the FCC’s review process, marking the first regulatory step for the ambitious space-based computing network.

FCC opens SpaceX’s proposal for comment

In a public notice, the FCC’s Space Bureau stated that it is accepting SpaceX’s application to deploy a new non-geostationary satellite system known as the “SpaceX Orbital Data Center system.” As per the filing, the system would consist of “up to one million satellites” operating at altitudes between 500 and 2,000 kilometers, using optical inter-satellite links for data transmission.

The FCC notice described the proposal as a long-term effort. SpaceX wrote that the system would represent the “first step towards becoming a Kardashev II-level civilization – one that can harness the Sun’s full power.” The satellites would rely heavily on high-bandwidth optical links and conduct telemetry, tracking, and command operations, with traffic routed through space-based laser networks before being sent to authorized ground stations.

FCC Chairman Brendan Carr highlighted the filing in a post on X, noting that the Commission is now seeking public comment on SpaceX’s proposal. Interested parties have until early March to submit comments.

What SpaceX is proposing to build

As per the FCC’s release, SpaceX’s orbital data center system would operate alongside its existing and planned Starlink constellations. The FCC notice noted that the proposed satellites may connect not only with others in the new system, but also with satellites in SpaceX’s first- and second-generation Starlink networks.

The filing also outlined several waiver requests, including exemptions from certain NGSO milestone and surety bond requirements, as well as flexibility in how orbital planes and communication beams are disclosed, as noted in a Benzinga report. SpaceX noted that these waivers are necessary to support the scale and architecture of the proposed system.

As noted in coverage of the filing, the proposal does not represent an immediate deployment plan, but rather a framework for future space-based computing infrastructure. SpaceX has discussed the idea of moving energy-intensive computing, such as AI workloads, into orbit, where continuous solar power and large physical scale could reduce constraints faced on Earth.
