Purpose/Objectives: Wearable devices and mobile health applications are gaining consideration in the healthcare market. Apple Inc. has received much attention after its release of the Apple Watch and healthcare applications (Apps) for the iPhone. In 2004, we had developed Wearable Pulse Sensor as a part of our Wireless Wearable Physiological Monitors (WWPM) project (Ohyanagi, 2007; Miyazaki, 2008; Miyazaki 2012). In this project, we developed non-invasive wearable wireless monitors to provide physiological information to promote the wellness of society in a cost effective and efficient manner. At the time, the health care industry was not ready to incorporate information and communication technologies data in continuing care or homecare. The objective of this presentation is to show how the WWPM system, invented in 2004, can be adapted for the Apple Watch and iPhone for use in homecare. Examples include pulse and heart rate monitoring. Methodology/Approach: The WWPM system consists of three components: Wireless Physiological Sensor, Wireless Station and Central Server. The Wireless Physiological Sensor looks and functions like a watch, measures pulse rate, displays messages, and sends client's responses to health professional. The Wireless Station is located in a client's home and works as a gateway between the Wireless Physiological Sensor and the Central Server. The Wireless Station communicates with the Wireless Physiological Sensor and the Central Server using Bluetooth technology and the Internet, respectively. The Wireless Station provides audio reminders a client, for example, to take medicine and check blood sugar level. The audio reminder can be programmed with a family member's voice and in a client's native language. The Central Server is a web server and used to customize a client's schedule of the Wireless Physiological Sensor and the Wireless Station. The data are uploaded to the Central Server. To compare the technology's ability to measure pulse and heart rates, the first author wore both devices on his left wrist and measured his pulse and heart rates simultaneously. Finding/Results: We adapted the WWPM system so that: (a) the Apple Watch is used in place of the Wireless Physiological Sensor; (b) the iPhone is used in place of both the Wireless Station and part of the Central Server; (c) a calendar service is used for making a schedule for each client; (d) Apps for iPhone and Apple Watch use notifications as bi-directional communication tools. The pulse and heart rates measured by the Wireless Physiological Sensor and the Apple Watch were different by two or less values but Apple Watch could show the first rate about six seconds earlier than the Wireless Physiological Sensor. Furthermore, the pulse and heart rates were inaccurately measured if the subject moved his left arm during the measurement, as disclosed by Apple Inc. on its support page. We confirmed it by using Polar Bluetooth smart H7 heart rate sensor with the Wireless Physiological Sensor and the Apple Watch. Conclusion/Implications/Recommendations: The WWPM system can be adapted for use in with innovative consumer health products that use telecommunication, such as the Apple Watch and iOS Apps. 140 Character Summary: This paper presents our Wireless Wearable Physiological Monitors system adapted for use in with innovative health consumer products such as Apple Watch and iPhone.
