Smart" tablets are implanted into microchips to emit low power signals
Release date: 2010-09-02
A pharmaceutical company in the United States has developed a "smart" tablet that can help patients develop the habit of taking medication on time, and allows doctors to keep abreast of the patient's physical condition. The current tablet is still in clinical trials. Send a text message to remind you of the drug The secret of the "smart" tablet lies in the square microchip. The chip is made of an edible material that emits a low-power digital signal under the action of gastric juice as it enters the stomach.
The receiver attached to the body or implanted under the skin can receive the signal, then decode, transmit the information to the mobile phone, and display the time of the next medication and some health-related data in the form of a short message.
If you forget to take the medicine, the receiver will also send a reminder message to the patient's mobile phone.
In addition to reminding patients to take medication on time, “smart†tablets can send a message to the doctor to let the doctor know the patient's condition, such as whether to take the medication on time and the type of medication.
In addition, the chip can transmit vital signs such as heartbeat and body temperature of the patient, so that the doctor can understand which physiological changes caused by the drug and consider whether it is necessary to adjust the dosage.
The device, called "raisin", showed in the United States that the trial's on-time medication rate increased from 30% to 80%.
The British National Health Service and Imperial College, Royal Berkshire Hospital are preparing to recruit 40 heart patients for a four-month test.
These patients took the same medications during the test period, but the drugs contained chips.
Cardiologist Nicholas Peters said strict medication on time will improve the health of heart patients, reduce the need to go to the hospital and save on medical expenses. If the test results are satisfactory, a one-year test will be conducted on a larger scale in the future. Disintegration of the drug after dissolution of the drug The European Union awarded the "raisin" "CE" mark on the 13th, indicating that it meets food hygiene standards.
In the "raisin" device, a chip is placed in each tablet, and the chip disintegrates shortly after the drug dissolves. Researchers hope to develop chips that can be permanently implanted in the body, and can track the patient's condition for years, not just hours.
Researchers named the more advanced physical condition tracking device "Body 2.0." With the installation of "Body 2.0", the doctor may find signs of a few hours or a few days before the patient's illness.
The prospect of installing a permanent tracking device in the body is good, but it faces some difficulties. For example, how to avoid the tracking device being damaged in the humid environment and the "offensive" of the enzyme and immune system, how to avoid it causing body infection and the like.
