Researchers have developed a 3D-printed pen containing magnetic ink that will assist establish Parkinson’s illness by means of handwriting evaluation. The system captures movement patterns that might point out the presence of the neurodegenerative dysfunction, in accordance with a examine revealed in Nature Chemical Engineering. The pen incorporates a silicone tip embedded with magnetic particles and ink with magnetized floating particles that produce electrical indicators when used for writing.
The workforce from the College of California, Los Angeles examined the pen with individuals drawing wavy traces, spirals, and writing each on surfaces and within the air. Utilizing machine studying fashions to investigate the info from 16 individuals, together with three with Parkinson’s, one mannequin achieved a mean accuracy of 96.22% in distinguishing sufferers with the situation from wholesome people.


“It is rather cost-effective and totally accessible for decrease revenue international locations,” stated Prof Jun Chen, co-author of the examine, noting that the system would hook up with a telephone app for evaluation. Chen added, “We’re utilizing the handwriting-generated electrical sign to quantify the tremor throughout [writing].”
Consultants not concerned within the analysis expressed cautious optimism. Chrystalina Antoniades from the College of Oxford described the strategy as “fascinating and intriguing” however emphasised that additional testing is required. She famous that handwriting adjustments symbolize simply one in every of many Parkinson’s signs, stating, “It may be complementing what we already discovered, selecting up one thing that is likely to be tough to see.”
Becky Jones from Parkinson’s UK welcomed the work whereas highlighting the examine’s restricted scope. “Whereas this examine could be very small, involving simply three individuals with Parkinson’s, it presents a brand new mind-set about prognosis by measuring adjustments in handwriting, which will be an early symptom,” Jones stated. She referred to as for bigger, extra various research to higher perceive the tactic’s potential for supporting earlier and extra correct diagnoses.
Greater than 10 million individuals worldwide are estimated to be residing with Parkinson’s illness. Present diagnostic strategies both depend on subjective remark of motor signs or require specialised tools and highly-trained professionals to investigate biomarkers. Early prognosis may also help sufferers entry remedies and assist sooner, although there may be at present no definitive check or remedy for the situation.
