These slides use concepts from my (Jeff Funk) course entitled analyzing hi-tech opportunities to analyze how wireless healthcare are becoming economic feasible. Improvements in microprocessor and transceiver ICs, MEMS, photo-sensors, and other electronic components are making wireless healthcare economically feasible. These slides show how improvements in these components are making capsule endoscopy, smart drug delivery, and digital pills economically feasible. Capsule endoscopy involves sending a small device through the body, particularly the digestive system, to take images. Further improvements in electronic components are needed to further reduce the size of these devices. Drugs can be dispensed through smart pills at programmed times or can be triggered by sensors that detect the correct location. Digital pills send signals to mobile phones or other devices when the pills have been taken. The slides conclude by discussing the role of mobile phones in increasing the number of wireless healthcare applications.
