The Role of Wireless Technologies in Shaping Digital Healthcare

【Abstract】

Viral pandemics, exemplified by COVID-19, underscore the increasing importance of non-contact, remote patient monitoring via wireless medical devices. These systems collect medical health metrics and vitals, such as blood pressure, heartbeat, respiration rate, hydration levels and various biomarkers of different diseases from the user’s devices. Typically utilizing medical wearables and mobile applications, users transform their smartphones into portable laboratories for advanced diagnostics and continuous disease tracking. In this talk, I will discuss the wireless, flexible devices such as an implantable cardiac monitor, and different non-invasive platforms to improve the digital healthcare system, overcoming spatial-temporal gaps in current healthcare provision.

病毒大流行,以COVID-19为例,突显了通过无线医疗设备进行非接触式、远程患者监测的重要性日益增加。这些系统收集医疗健康指标和生命体征,如血压、心跳、呼吸率、水分水平以及不同疾病的各种生物标志物,从用户的设备中获取。通常利用医疗可穿戴设备和移动应用程序,用户将他们的智能手机转变为便携式实验室,用于高级诊断和持续疾病跟踪。在本次演讲中,我将讨论无线、柔性设备,如植入式心脏监测器,以及不同的非侵入性平台,以改善数字医疗系统,克服当前医疗提供中的空间-时间差距。

Shedding light on precision biosensing: from wearable bioelectronics to single-particle detection

【ABSTRACT】

Optical-based biosensing platforms have the potential to enhance our insights into personalized, real-time diagnostics. Wearable bioelectronics are essential in the development towards such patient-centered technologies, yet current limitations in biosensing also emphasize the need of understanding the fundamentals of biosensing on a single molecule level. In this talk, I will discuss our efforts in the development of soft, flexible wearable optical-based bioelectronics for the monitoring of cerebral hemodynamics on one of the most fragile patient populations: neonatal and pediatric patients. The discussion will then be followed by our work on an aptamer-based biosensor for the real-time, optical detection of endotoxin, a deadly pyrogen. We demonstrate the regeneration and reusability of the sensor suitable for repeated endotoxin measurement. The single molecule detection mode is enabled by dark field microscopy. These platforms have the potential to advance biomarker detection to safeguard the whole value chain: from healthcare products to the health of our patients for real-time detection and diagnostics.

基于光学的生物传感平台有潜力增强我们对个性化、实时诊断的洞察力。可穿戴生物电子设备在发展以患者为中心的技术中至关重要,然而当前生物传感的局限性也强调了在单分子水平上理解生物传感基本原理的必要性。在本次演讲中,我将讨论我们在开发柔软、灵活的可穿戴基于光学的生物电子设备方面的努力,用于监测脑血流动力学,特别是在最脆弱的患者群体中:新生儿和儿科患者。接着,我将讨论我们基于适配体的生物传感器的工作,用于实时、光学检测内毒素,这是一种致命的热原。我们展示了传感器的再生和可重复使用性,适用于重复的内毒素测量。暗场显微镜使单分子检测模式成为可能。这些平台有潜力推进生物标志物检测,以保障整个价值链的安全:从医疗产品到我们患者的健康,实现实时检测和诊断。

Wearables for Continuous Hemodynamic Monitoring and Classification

【ABSTRACT】

Heart failure occurs in approximately 64 million people annually and is one of the leading causes of death globally. Characterized by periods of stability punctuated with life-threatening spells of instability, patients periodically travel to clinics for cardiac assessments. While vital, these visits incur extensive resources and only provide data during the time of evaluation. Wireless, non-invasive, monitoring devices (i.e. wearables) are gaining popularity with patients and clinicians for providing data in between hospital visits – allowing for improved insight and early, timely intervention. However, many of these devices are still limited to heart rate, pulse oximetry, and activity levels.

Here, we summarize our recent progress towards comprehensive cardiovascular monitoring and status classification by utilizing multiple, custom, time-synchronized wearables. Through wearable spectrometers and pulse arrival time models, we target independent correlates of hemodynamic function that not just estimate blood pressure, but also the regulatory mechanisms by which it is maintained or modulated. When applied to remote patient management, we posit that this will enable clinically actionable insights via the ability to classify and monitor types of heart failure and its progression in remote environments.

心力衰竭每年影响约6400万人,是全球主要的死亡原因之一。它以稳定期和生命威胁的不稳定期为特征,患者需要定期前往诊所进行心脏评估。虽然这些访问至关重要,但它们消耗了大量资源,并且仅在评估期间提供数据。无线、非侵入式监测设备(即可穿戴设备)因其能在医院访问之间提供数据而受到患者和临床医生的欢迎——这有助于提高洞察力并实现早期及时干预。然而,许多这些设备目前仍仅限于监测心率、脉搏血氧饱和度和活动水平。

在这里,我们总结了我们在利用多个定制的、时间同步的可穿戴设备进行全面心血管监测和状态分类方面的最新进展。通过可穿戴光谱仪和脉搏到达时间模型,我们针对血流动力学功能的独立相关因素,不仅估计血压,还包括维持或调节血压的调节机制。当应用于远程患者管理时,我们认为这将通过能够在远程环境中分类和监测心力衰竭的类型及其进展,从而提供临床上可行的洞察。
