Graphene device monitors blood pressure continuously


C&EN: new blood pressure monitoring device made from graphene could help people keep better track of their cardiovascular health. The array of stick-on graphene sensors, dubbed graphene electronic tattoos, can measure blood pressure continuously over the course of hours. Data from this device would give doctors a better overall picture of blood pressure than using measurements from a blood pressure cuff taken a few times a day.

“Blood pressure provides a holistic view of our cardiovascular system,” says Roozbeh Jafari, a biomedical engineer at Texas A&M University who led the development of the new device along with Deji Akinwande of the University of Texas at Austin. By monitoring blood pressure over the course of hours, rather than in once- or twice-daily measurements, healthcare professionals can eliminate noise in their data—like blood pressure spikes caused by the stress of a doctor’s visit. Also, Jafari says, the graphene device is thin and weightless. It doesn’t squeeze like a traditional blood pressure cuff; it’s simply worn on the forearm (Nat. Nanotechnol. 2022, DOI: 10.1038/s41565-022-01145-w).

The first sphygmomanometer—the device that is the basis for modern blood pressure cuffs—was invented in 1881. While there have been improvements to the device, the technology is essentially the same, Jafari says. The new graphene-based device uses an entirely different process for monitoring blood flow.

Graphene—a material that consists of one or a few sheets of carbon atoms strung together like chicken wire—has the perfect properties for a blood pressure monitor, Jafari says. It can make close contact with skin and has ideal electronic properties. The graphene sensors used in the device were first reported in 2017 (ACS Nano,

DOI: 10.1021/acsnano.7b02182). In the new blood pressure monitor, the carbon tattoos inject small electrical currents into the arm and then measure voltage, which correlates with changes in blood volume.

The team developed a computer algorithm that translates those changes in blood volume to the traditional systolic and diastolic blood pressure measurements. Read More …

Opinion: My wife/Editor found this post and asked if I thought this could have a connection to Bible Prophecy.

I hesitated in answering as I wanted to make sure I wasn’t overreaching to make a connection to God’s word, so I asked our back-up editor for his opinion and he said this:

“Anything that monitors/surveils your vitals can be used in nefarious ways. This is just a very small puzzle piece to a much larger picture of an authoritarian system.”

I agree, so here we go.

In my Saturday interview with Jimmy DeYoung Jr. on Prophecy Today Radio, we spoke of how Central Bank Digital Currencies are almost here. We spoke about how intrusive government could become by knowing the spending habits of every citizen, and we spoke about the unlimited dictatorial power that authoritarian government leaders will have when money is able to be programmed.

We also spoke about while Europe is pushing back on digital euros, the US is strangely quiet.

Once money is controlled:

  • Healthcare insurance will depend on your food, alcohol and tobacco purchases
  • Transportation will be confined to government approved vehicles/busses
  • Air-conditioning and heat will be controlled by government thermostats
  • Purchases of guns and ammunition will be strictly prohibited
  • Red Flag laws will encourage families to report on each other
  • Free speech will be limited to what government bureaucrats approve of, already started by social media outlets

Wearable digital devices as the writer of the article points out will be a benefit for a while, but as our friend VS said “they can be used in nefarious ways”.

When he appears on the world stage, Antichrist will require a ‘mark’ (Rev. 13:16-17) of some sort that will enable a person to buy or sell. A graphene electronic sensor or something similar just may be the answer.
