About

Muhammad Hamidullah is a leading researcher in microelectromechanical systems (MEMS), with a focused expertise in developing miniaturized force sensors for biomedical applications, particularly in minimally invasive surgery (MIS) and interventional cardiology. His major contributions center on the design and fabrication of tri-axial force sensors that can be seamlessly integrated into surgical tools like guidewires and needles. Notably, his 2012 work on a MEMS tri-axial force sensor with an integrated mechanical stopper for guidewire applications has garnered 31 citations, establishing a foundation for tactile feedback in catheter-based procedures. He advanced this concept in 2014 with a ring-shaped sensor using silicon nanowires (SiNWs) as piezoresistive elements, achieving a compact 200 µm × 200 µm sensor area—a design that enables smart integration on distal guidewire tips. Hamidullah’s research directly addresses the critical need for quantitative tactile feedback in robotic-assisted MIS, as demonstrated in his 2012 study on a sensorized surgical needle. His work bridges the gap between MEMS fabrication and clinical tool design, offering surgeons enhanced haptic perception during delicate procedures. Through these innovations, Hamidullah has significantly impacted the field of smart medical instruments, paving the way for safer and more precise interventions.
