Engineers use the heart’s energy to self-charge a bio-implant device
Engineers from Dartmouth College have created a dime-sized device that could allow implanted biomedical devices to be charged indefinitely using the natural kinetic (motion) energy of the heart. In a study conducted over the last three years and published in the journal Advanced Materials Technologies in January this year, an implant with piezoelectric materials was combined with a pacemaker to convert heartbeats into electricity. Considering the 5-10 year replacement requirement for the average battery-powered implantable biomedical device, this invention could soon mean a significant reduction in invasive and risky surgeries.
Piezoelectricity is mechanical stress converted into electricity. Pressure, sound waves, and other vibrations coming into contact with piezoelectric materials cause the materials’ atoms to shift, creating positive and negative charges. In the Dartmouth invention, moving heart tissue squeezes a flexible container with piezoelectric material inside, creating charges which are sent through the pacemaker’s lead wire back to its battery. This continuous charging cycle, in theory, would enable any biomedical implant where motion was a component of the device’s location to last for the lifetime of a patient.
The project’s engineers have two more years of National Institutes of Health (NIH) funding to complete a pre-clinical and regulatory approval process, and a commercially available version is expected to be about five years away. The potential for the device has already been recognized by significant players in the biotech industry. Andrew Closson, one of the study’s authors, explained in a news article about the device, “There is already a lot of expressed interest from the major medical technology companies…[and we are]…moving forward with the entrepreneurial phase of this effort.”
The idea of harvesting heart energy is not a new one. A team of researchers from the University of Illinois demonstrated a proof-of-concept in 2014 using a flexible, piezoelectric patch on anesthetized sheep. After stitching multiple patches in an optimal orientation on the sheep’s heart, the voltage produced was found to be sufficient to power a standard pacemaker. Other devices that could be powered by this type of technology include cochlear implants and implantable defibrillators.
Implantable electronic medical devices are frequently seeing improvements in the field of biotechnology and thus directly relevant to the Dartmouth engineers’ invention. In November of last year, a study was published demonstrating the effectiveness of a spinal implant used to amplify brain signals. After epidural electrical stimulation was delivered to the spinal cords of three paralyzed participants, all were able to regain motion in their lower limbs. Piezoelectric functionality in a device like this one would be a natural inclusion.

Tesla preps for a harsh potential reality if Musk comp vote doesn’t go to plan
A successful vote for Tesla would see the compensation package get approved. But there is always the possibility of a rejection, which would likely see Musk leave the company.
Tesla could be forced to look for a new CEO in the coming months, as a crucial November 6 Shareholder Meeting vote will determine whether Elon Musk will stick around.
A major vote is coming up at the 2025 Tesla Shareholder Meeting, as investors will determine whether Musk should be given a new compensation plan that would award him up to $1 trillion and more than one-fourth of the total voting power within the company.
Tesla board chair reiterates widely unmentioned point of Musk comp plan
A successful vote for Tesla would see the compensation package get approved. But there is always the possibility of a rejection, which would likely see Musk leave the company.
“My fundamental concern with regard to how much voting control I have at Tesla is if I go ahead and build this enormous robot army, can I just be ousted at some point in the future? That’s my biggest concern,” Musk said at last week’s Earnings Call. “That’s what it comes down to in a nutshell. I don’t feel comfortable wielding that robot army if I don’t have at least a strong influence.”
Tesla Board of Directors Head Robyn Denholm has been on somewhat of a PR tour over the past few days, answering questions about the compensation plan, which is among the biggest issues currently for the company.
Denholm told Bloomberg yesterday that Tesla investors need to be prepared for Musk to abandon ship if the package is not approved, which brings on a new question: Who would take over the CEO role?
That is a question Denholm also answered yesterday, bringing forth the conclusion that Tesla would not look for an outside hire if Musk were to leave the company. Instead, it would promote someone internally.
The way it was reported by Bloomberg and Reuters seems to make it seem as if Tesla is preparing for the worst, as it states the company “is looking at internal CEO candidates,” not preparing to do so.
Of the executives at Tesla who immediately come to mind as ideal candidates for a potential takeover should Musk leave, Tesla China President Tom Zhu and Head of AI Ashok Elluswamy both come to mind. Zhu has monumental executive experience already, as he was appointed to the role of Senior VP of Automotive back in December 2022.
He then returned to China in 2024.
It seems Tesla wants to align its future, with or without Musk, on the same path that it is currently on, and internal candidates might have a better idea of what that looks like and truly means.

Tesla Full Self Driving (FSD) is nearing approval in a new country
As per the official, Tesla’s Full Self-Driving system could be enabled in Israel in the near future.
It appears that Tesla FSD (Supervised) is heading to a new country soon, at least based on comments from Israel’s Transport and Road Safety Minister Miri Regev.
As per the official, Tesla’s Full Self-Driving system could be enabled in Israel in the near future.
Israeli drivers are pushing for FSD rollout
While Tesla’s FSD is already operational in markets like the U.S., Canada, and Australia, Israeli owners have long been unable to use the feature due to regulatory barriers. Despite its premium price tag, however, numerous Tesla owners in Israel have noted that the technology’s safety benefits, at least when approved for real-world use in the country, justify its cost.
It was then no surprise that nearly 1,000 Tesla owners in Israel have already petitioned the government to greenlight FSD’s domestic release in Israel. In a post on X, Regev seemed to confirm that FSD is indeed coming to Israel. “I’ve received the many referrals from Tesla drivers in Israel! Tesla drivers? Soon you won’t need to hold the steering wheel,” she wrote in her post.
FSD’s regulatory support in Israel
Regev stated that her Ministry views promoting innovative technologies as essential to improving both road safety and smart mobility. A working group led by Moshe Ben-Zaken, Director General of the Ministry of Transportation has reportedly been tasked to finalize the approval process, coordinating with regulatory and safety agencies to ensure compliance with international standards.
In a comment to Geektime, Israel’s Ministry of Transportation and Road Safety noted that Regev is indeed supporting the release of FSD in the country. “Minister Regev sees great importance in promoting innovative technologies, and in particular in the entry of advanced driving systems (FSD) into the Israeli market, as part of the ministry’s policy to encourage innovation, safety, and smart transportation,” the Ministry stated.

Bank of America raises Tesla PT to $471, citing Robotaxi and Optimus potential
The firm also kept a Neutral rating on the electric vehicle maker, citing strong progress in autonomy and robotics.
Bank of America has raised its Tesla (NASDAQ:TSLA) price target by 38% to $471, up from $341 per share.
The firm also kept a Neutral rating on the electric vehicle maker, citing strong progress in autonomy and robotics.
Robotaxi and Optimus momentum
Bank of America analyst Federico Merendi noted that the firm’s price target increase reflects Tesla’s growing potential in its Robotaxi and Optimus programs, among other factors. BofA’s updated valuation is based on a sum-of-the-parts (SOTP) model extending through 2040, which shows the Robotaxi platform accounting for 45% of total value. The model also shows Tesla’s humanoid robot Optimus contributing 19%, and Full Self-Driving (FSD) and the Energy segment adding 17% and 6% respectively.
“Overall, we find that TSLA’s core automotive business represents around 12% of the total value while robotaxi is 45%, FSD is 17%, Energy Generation & Storage is around 6% and Optimus is 19%,” the Bank of America analyst noted.
Still a Neutral rating
Despite recognizing long-term potential in AI-driven verticals, Merendi’s team maintained a Neutral rating, suggesting that much of the optimism is already priced into Tesla’s valuation.
“Our PO revision is driven by a lower cost of equity capital, better Robotaxi progress, and a higher valuation for Optimus to account for the potential entrance into international markets,” the analyst stated.
Interestingly enough, Tesla’s core automotive business, which contributes the lion’s share of the company’s operations today, represents just 12% of total value in BofA’s model.
