Title

Wearable Biosensor in Earring Form Factor

Abstract

Disclosed is an earring form factor for a wearable biosensor with a disposable microelectro-mechanical system/nanoelectro-mechanical system (MEMS/NEMS)-based sensing electrode.

Problem

In the field of wearable devices and biosensors, most available wearables are in a visible bracelet form factor and are not fashionable. This often excludes women from widely adopting wearable technologies.

Medical sensors require direct contact with skin, blood, or other bodily fluids; however, placement and foreign body responses limit a sensor's useful life. Cost, accuracy, and power limitations to most biosensors also limit usage. In addition, radio frequency (RF) communication and batteries increase the cost of disposable sensors, which makes the technology cost-prohibitive for the general consumer.

Other devices on the market may not provide continuous direct contact with the user's skin and are not capable of continuous monitoring of various health parameters including pulse, heart rate, oxygen saturation in blood, hemoglobin level, and blood sugar level.

A biosensor system is needed that is cost-effective, discreet, fashionable, and allows continuous blood-based bio-sensing.

Solution/Novel Contribution

The novel contribution is an earring form factor with a disposable microelectro- mechanical system/nanoelectro-mechanical system (MEMS/NEMS)-based sensing electrode on the earring back. This is a good solution because jewelry worn on the ear is in immediate contact with skin, allowing the chip to continually monitor the user's vital signs. A permanent earring back can be used with multiple earring fronts either in push or screw-in format.

The novel design includes a disposable sensing element, a battery, and storage and communication devices on the earring back. The design places no limitations on the style of the front of the earring. MEMS/NEMS-based disposable sensing element structures enable blood-based bio-sensing. The design also includes structures and methods of attachment for the disposable sensing elements. The structure and method for battery recharging utilize the hole in the earring back as a point of electrical contact with the battery charger. Wi-Fi transmittal is also a feature.

Method/Process

The primary structure incorporates the battery, storage, and/or communication devices. On the opposite side of the earring back stud is the sensing element. This is not
