Investigation of photoplethysmography and arterial blood oxygen saturation from the ear-canal and the finger under conditions of artificially induced hypothermia [PDF]
Pulse oximeters relay on the technique of photoplethysmography (PPG) to estimate arterial oxygen saturation (SpO2). In conditions of poor peripheral perfusion such as hypotension, hypothermia, and vasoconstriction, pulse oximeters become inaccurate or ...

Pleomorphic adenoma presenting with conductive hearing loss in the ear canal: a case report and review of the literature [PDF]
INTRODUCTION: Pleomorphic adenoma accounts for 65 percent of all salivary gland tumors. It has been identified in several anatomical regions, but pleomorphic adenoma arising in the ear canal, first described in 1951, is extremely rare. CASE PRESENTATION:

Cochlear-bone wave can yield a hearing sensation as well as otoacoustic emission
A hearing sensation arises when the elastic basilar membrane inside the cochlea vibrates. The basilar membrane is typically set into motion through airborne sound that displaces the middle ear and induces a pressure difference across the membrane.

Squamous papilloma in the external auditory canal
Squamous papilloma is a benign neoplasm and most commonly occurs in the oral cavity or larynx but rarely in the external auditory canal. Human papilloma virus is thought to be the cause. The effective treatment is surgical excision.

Reconfigurable Magnetic Soft Microrobot for Acoustically Triggered Targeted Bacterial Sterilization
Reconfigurable magnetic soft microrobots integrate in situ‐grown piezoelectric zinc oxide nanorods that produce reactive oxygen species upon acoustic excitation. Combining magnetically guided transport with thermally induced planar reconfiguration, the microrobots achieve targeted delivery and enhanced bacterial sterilization through efficient on ...

In-ear photoplethysmography for central pulse waveform analysis in non-invasive hemodynamic monitoring [PDF]
In recent years, the analysis of the photoplethys-mographic (PPG) pulse waveforms has attracted much research focus. However, the considered signals are primarily recorded at the fingertips, which suffer from reduced peripheral perfusion in situations ...
