#Edible batteries could power smart medicine pills A flexible biodegradable battery just may be what the doctor ordered.
What happens when you forget a dose of medication your doctor has prescribed for a condition that relies on the timed delivery of your medicine?
Enter the#smart pill, a sensor-equipped capsule that you only need to take just once.
The smart pill releases medicine on a schedule or as your body needs it. But what would power that pill?
The answer is simple: an edible#battery.####Obviously, creating smart pills with their own sensors to regulate medicine in the body is a great idea,

The scheme hopes to become self-sustaining by requiring milestone payments as drugs move from laboratory to clinic and from additional partnerships and screening services."

when drugs or neurotransmitters lock into the receptors from outside the cell, they trigger the release of other chemicals inside the cell.
Some drugs bind at more than one receptor, setting off not-fully-understood reactions that can produce unwanted side effects.
To avoid this, researchers want to fine-tune drugs so that they activate only the desired signalling pathway.
some drugs that activate the 2b receptor have been thought to cause heart problems3, and have been withdrawn as unsafe.
They triggered both 1b and 2b with the powerful psychedelic drug LSD and one of its precursors, a migraine drug called ergotamine.
