Multi-wavelength Photoplethysmography Enabling Continuous Blood Pressure Measurement with Compact Wearable Electronics.

To fight the "silent killer" hypertension, continuous blood pressure (BP) monitoring has been one of the most desired functions in wearable electronics. However, current BP measuring principles and protocols either involve a vessel occlusion process with a cuff or require multiple sensing nodes on the body, which makes it difficult to implement them in compact wearable electronics like smartwatches and wristbands with long-term wearability.


ns Pulsed Electric Field-Induced Action Potentials in the Circuital Model of an Axon.

Pulsed electric fields with duration in the sub- and ns time scale (nsPEFs) increase the permeability of cell membranes, enabling the transport of normally impermeant molecules into or out of the cell (electroporation). Such effect is associated to intracellular alterations and indicates nsPEFs as a new stimulus to modulate cell functions. In particular, studies dealing with the application of nsPEFs to excitable cells suggest their use for the stimulation/inhibition of cell excitation. In this paper, the c...

Robotic Flexible Electronics with Self-Bendable Films.

Mechanical flexibility introduced in functional electronic devices has allowed electronics to avoid mechanical breakage, conform to nonplanar surfaces, or attach to deformable surfaces, leading to greatly expanded applications, and some research efforts have already led to commercialization. However, most of these devices are passively bendable by external driving forces. Actively bendable flexible thin film devices can be applied to new fields with new functionalities. Here, we report robotic flexible elec...

TSV-integrated thermoelectric cooling by holey silicon for hot spot thermal management.

The trends toward higher power, higher frequency, and smaller scale electronics are making heat dissipation ever more challenging. Passive thermal management based on high thermal conductivity materials or through-silicon vias (TSVs) may not provide sufficient cooling for hot spots reaching 1 kW cm, and active thermal management by thermoelectric cooling (TEC) may require large power consumption or suffer from a large off-state thermal resistance of thermoelectric materials. Here we address these issues by ...

In this paper, we present a 1-dimensional lumped parameter model of the CPUT to study its operation and investigate relevant design parameters for power transfer applications. The CPUT is modeled as an ultrasound driven piston coupled ...

The sit-to-stand muscle power test: An easy, inexpensive and portable procedure to assess muscle power in older people.

Skeletal muscle power has been demonstrated to be a stronger predictor of functional limitations than any other physical capability. However, no validated alternatives exist to the usually expensive instruments and/or time-consuming methods to evaluate muscle power in older populations. Our aim was to validate an easily applicable procedure to assess muscle power in large cohort studies and the clinical setting and to assess its association with other age-related outcomes.

A Three-Dimensional Printed Poly(vinyl alcohol) Substrate with Controlled On-Demand Degradation for Transient Electronics.

Electronics that degrade after stable operation for a desired operating time, called transient electrons, are of great interest in many fields, including biomedical implants, secure memory devices, and environmental sensors. Thus, the development of transient materials is critical for the advancement of transient electronics and their applications. However, previous reports have mostly relied on achieving transience in aqueous solutions where the transience time is largely pre-determined based on the materi...

Michel Foucault and the Problematics of Power: Theorizing DTCA and Medicalized Subjectivity.

This article explores Foucault's two different notions of power: one where the subject is constituted by power-knowledge relations and another that emphasizes how power is a central feature of human action. By drawing out these two conceptualizations of power, Foucault's work contributes three critical points to the formation of medicalized subjectivities: (1) the issue of medicalization needs to be discussed both in terms of both specific practices and holistically (within the carceral archipelago); (2) we...

Impact of consumer power on consumers' reactions to corporate transgression.

We addressed how individuals' power influences their judgments regarding corporate transgressions. Based on the Situated Focus Theory of Power, which theorizes that powerful people respond more in accordance to circumstantial factors, we tested the interaction of power and the type of corporate discourse offered by the accused company. Across two studies (overall N = 216), we experimentally primed power (Study 1) and manipulated participants' sense of direct control over the company (Study 2). We consistent...

Electronics of a Wearable ECG with Level Crossing Sampling and Human Body Communication.

In this paper, the human body communication (HBC) and level crossing sampling (LCS) are combined to design electronics for a wearable ECG. The ECG signals acquired by capacitively coupled electrodes are sampled with LCS in place of conventional synchronous sampling. In order to transmit signals through HBC at low frequencies (100 kHz, 1 MHz), an electric field sensor with high input impedance is adopted as the front end of the HBC receiver. The HBC channel gain is enhanced by more than 30 dB with the electr...

Laser Power Stabilization beyond the Shot Noise Limit Using Squeezed Light.

High levels of laser power stability are necessary for high precision metrology applications. The classical limit for the achievable power stability is determined by the shot noise of the light used to generate a power control signal. Increasing the power of the detected light reduces the relative shot noise level and allows higher stabilities. However, sufficiently high power is not always available and the detection of high laser powers is challenging. Here, we demonstrate a nonclassical way to improve th...
