Exploring the Acceptability and Feasibility of Remote Blood Pressure Measurements and Cognition Assessments Among Participants Recruited From a Safety-Net Emergency Department (Reach Out Cognition): Nonrandomized Mobile Health Trial

Exploring the Acceptability and Feasibility of Remote Blood Pressure Measurements and Cognition Assessments Among Participants Recruited From a Safety-Net Emergency Department (Reach Out Cognition): Nonrandomized Mobile Health Trial

Bluetooth-enabled BP cuffs offer advantages such as automatic transfer of readings to smartphone apps, graphical displays, and gamification to increase engagement. While small-scale studies have shown promise, the effectiveness of Bluetooth-enabled BP cuffs in larger, more diverse populations still needs to be tested [12].

Pilot Evaluations of Two Bluetooth Contact Tracing Approaches on a University Campus: Mixed Methods Study

Pilot Evaluations of Two Bluetooth Contact Tracing Approaches on a University Campus: Mixed Methods Study

While traditional contact tracing relies on interviewing cases and contacts in-person or by telephone, several countries augmented data collection using individual-level GPS data [15], Bluetooth technology [16], and other personalized data sources [17]. One technology in particular, Bluetooth, gained widespread attention in both the press [18] as well as scientific literature [19].

Predicting Depressive Symptom Severity Through Individuals’ Nearby Bluetooth Device Count Data Collected by Mobile Phones: Preliminary Longitudinal Study

Predicting Depressive Symptom Severity Through Individuals’ Nearby Bluetooth Device Count Data Collected by Mobile Phones: Preliminary Longitudinal Study

Mobile phone technology provides an unobtrusive, continuous, and cost-efficient means to capture individuals’ daily behaviors and statuses using a number of embedded sensors, such as accelerometers, GPS sensors, and Bluetooth sensors [6]. The embedded Bluetooth sensor can be used to record individuals’ local proximity information, such as the nearby Bluetooth device count (NBDC) that includes the Bluetooth signal of other phone users [7].

Measuring Mobility and Room Occupancy in Clinical Settings: System Development and Implementation

Measuring Mobility and Room Occupancy in Clinical Settings: System Development and Implementation

Indoor localization has seen significant technological improvements in recent years [2]—the relatively inexpensive Bluetooth low energy (BLE) beacons and Apple’s i Beacon standard have brought indoor localization closer to mainstream use. Most of the applications in hospitals and clinical settings have focused on process mining [3] or real-time localization [4], that is, locating people or assets quickly and accurately.

COVID-19 Contact Tracing and Data Protection Can Go Together

COVID-19 Contact Tracing and Data Protection Can Go Together

Unlike the contact point system, it only requires users to enable Bluetooth on their phone. Pan-European Privacy-Preserving Proximity Tracing (PEPP-PT) by the European consortium [3], as well as Google and Apple’s recently announced joint initiative [4], are following a very similar concept. We present a slightly modified version below. In order to detect whether two people have come into close enough physical proximity to risk an infection, one can use Bluetooth low energy technology.

Continuous Temperature-Monitoring Socks for Home Use in Patients With Diabetes: Observational Study

Continuous Temperature-Monitoring Socks for Home Use in Patients With Diabetes: Observational Study

The sensors embedded in the socks are connected to a small tag on the sock, which encases a microcontroller unit, battery, and Bluetooth chip (see Figure 1 A). The six sensors take temperature measurements at 10-second intervals to track temperature increases at the bottom of the user's feet, specifically at the hallux; metatarsal points (MTPs) 1, 3, and 5; midfoot; and heel (see Figure 1 B). The data are stored in the tag and sent via Bluetooth to the phone paired with each pair of socks.
