Microchips to be imbedded in pills?

Yes, it’s true. Proteus Biomedical has announced that they will be launching a innovative product that imbeds microchips in pills so that patients can be monitored by their health care professionals and even their families.

The purpose of the monitoring is to be sure that patients are taking their medications properly and on time and to also monitor a range of additional patient information including respiration rate, heart rate, temperature, sleep patterns and physical activity. It is estimated that up to 50% of all patients take their medication improperly so this will assist health care professionals and family member with the patient’s drug regimen.

The sensors are about the size of a grain of sand. The sensor-enabled tablets are called Helius. The Helius can be taken with pills or incorporated into medications by the drug manufacturers. Once ingested, the sensors are activated by stomach acid. Each sensor contains a very small amount of copper and magnesium which react with stomach acid to create the power necessary to generate a digital signal. Through an adhesive patch on the skin, the digital signal is read and and the data transmitted through the patient’s cell phone.

Don’t look for the microchipped pill just yet. Proteus Biomedical will be introducing their new product in the UK first.

What are breadboards?

Plastic BreadboardBreadboards are a simple solution for circuit building, especially when you need to prototype or test a circuit. Constructed of plastic, a solderless breadboard contains hundreds of spring-loaded connection sockets (also called tie points) which connect the leads for through-hole electronic components and 22 AWG wire to form an electronic circuit. One key feature of breadboards is that they require no solder to connect your components making testing or prototyping a circuit very quick and painless.

How do breadboards work?

A breadboard is constructed on hundreds of holes arranged in vertical and horizontal rows. The outer rows which run lengthwise across the circuit board are generally reserved for the circuit’s power supply. The interior rows of holes are where the electronic components are inserted. Each row of holes forms a node; that is, any components that reside on the same node will be connected when they are inserted into a hole in that same row, or node. This is because under each row is a copper plate that connects the holes to each other.
